Five concrete measures to shorten work time with RTK

RTK is being adopted across many sites as a method for obtaining high-precision positional information in a short time. In conventional work, observations by multiple personnel, equipment setup, securing lines of sight, and repeated re-observations tend to take a lot of time, and more work hours were spent on preparation and verification than on the act of measuring itself. Introducing RTK can greatly reduce some of these burdens, but simply bringing in the equipment does not automatically make work faster. In practice, the amount of time that can be saved varies greatly depending on the accuracy of pre-work preparation, how control points are handled, the planning of on-site movements, the way verification procedures are organized, and the division of roles across the team.

On site, there are many cases where how operations are organized affects work time more than the RTK system’s performance itself. Time spent waiting for positioning to stabilize, time spent returning because of coordinate mix-ups, time spent retracing steps due to a poor travel route, time spent redoing work because of insufficient checks, and time lost when different operators use different procedures and cause confusion—all these small losses add up and can greatly inflate the total work time. Conversely, if you carefully reduce each of these losses one by one, the way work progresses can change dramatically even with the same number of people and the same equipment.

In this article, we organize and explain five concrete measures to shorten working time with RTK. Focusing on the core practical areas—preparation, control point management, movement efficiency, verification procedures, and team operations—we delve into the points that truly produce time savings on site, rather than merely providing equipment descriptions. This will be useful not only for those planning to review RTK operations but also for those who have already implemented RTK and feel it isn’t delivering the expected speed.

Introduction

A major attraction of RTK is that it allows you to proceed with work while checking coordinates on the spot. Because you can determine positions without waiting for post-processing, it is well suited to situations that demand immediacy in a variety of tasks such as surveying, layout, as-built verification, site-condition assessment, and inspection records. However, what matters in practice is not whether RTK is fast, but how much it can reduce waste within the overall workflow on site.

For example, if you consider the sequence of turning on the equipment, connecting to correction information, waiting for positioning to stabilize, moving to the target point to observe, checking the recorded data, and heading to the next point, the time spent on the observation itself is only a part of the process. Rather, peripheral tasks—such as connection troubles caused by inadequate preparation, failure to verify known points, poor observation sequencing, recording errors, and misunderstandings among personnel—tend to drive up the overall time.

Therefore, when considering time savings with RTK, it is insufficient to look only at positioning accuracy. You need to identify where work tends to stall, which decisions take time, and which processes are producing rework, and then redesign the workflow. On-site time savings begin not with flashy innovations but with creating a state in which work can proceed without hesitation at the same quality every time.

In particular, on sites where multiple people are involved, operations that depend on individual experience tend not to result in time savings. If work is fast only when experienced personnel are present but slows down when the person in charge changes, stable productivity cannot be achieved. It is important that whoever is assigned can start with the same workflow, verify against the same standards, and record in the same format. RTK is a high-performance tool, but to fully leverage its capabilities, on-site operational design is essential.

From here, I will explain, in order, five specific measures that are particularly effective at shortening work time, so you can visualize how to implement them on site.

Specific Measure 1 Standardize pre-site preparations to speed up the start of on-site work

If you want to shorten work time with RTK, the first thing to reexamine is your preparation before arriving on site. On many sites, people tend to blame time-consuming delays on on-site positioning or movement, but in reality insufficient organization before departure causes the biggest losses. If you enter the site with necessary information or settings unclear, confirmations will concentrate immediately after work begins, forcing you to stop during the time when you most need to be focused.

What's important in advance preparation is not just gathering the items you'll need. You must decide beforehand the assumptions for the work — the purpose of the observations, the coordinate system to be used, the locations of reference points, the priority of observation targets, and the rules for storing data. If these are left unclear, personnel on site will start consulting with one another and time will be lost even before any measurements are taken.

First, one of the most effective measures is to standardize the preparation items for each site. Even when sites differ, the items to be checked are largely common. If you prepare in advance the things to be checked each time—such as equipment charging status, verification of communication methods, connection conditions for correction services, maps of the work area, the presence or absence of known points, rules for record names, and the destination for saving results—the quality of preparation will be less likely to vary even when the person in charge changes.

Next, it is also important not to rely too much on paper or verbal information brought to the site. If the list of target points, the work sequence, caution points, entry routes, and access restrictions exist only in the person in charge’s head, on-site decisions will be delayed. Organizing drawings, point lists, and site notes in advance so that anyone can make the same judgments will reduce hesitation during movement and observations.

Initialization of settings is another point that is easy to overlook. If the previous site’s settings remain in place, the connection targets, projection conditions, and recording formats may differ, and work can proceed without anyone noticing. These kinds of mistakes are hard to detect on site and can result in major rework later, making them losses you most want to avoid. Simply organizing the settings used for each site and making them quick to check before starting can greatly reduce the likelihood of rework.

Another key point of advance preparation is to decide the actions to take immediately after starting. If, upon arriving on site, you spend time deciding where to power up the equipment, in what order to check the known points, and where to begin the main observation, the first 30 minutes or so after starting will be the most inefficient. Conversely, if the actions for the first 10 minutes are decided, startup will be faster and the entire day's work will be more stable.

In practice, when a problem occurs first thing in the morning, that delay drags on all day. Issues such as being unable to establish a connection, not finding known points, or having different assumptions also erode workers' concentration. That is why shortening RTK setup time should start not with trying harder after arriving on site, but with creating a state in which you can act without hesitation the moment you arrive.

Standardized pre-preparation is not merely for checking; it’s a mechanism to speed up the start of work on site. The more thorough the preparations, the less you have to think on site, allowing you to focus on the observations and decisions that should properly take your time. If you are using RTK but it isn’t as fast as you expected, an effective first step is to review whether there is room for improvement in the preparations made the day before going to the site.

Specific Measure 2: Review Reference Point Operations to Reduce Hesitation and Re-measurements

When considering a reduction in work time using RTK, reviewing the operation of reference points is extremely important. On site, even if the observations themselves are fast, if the reference is ambiguous the whole workflow comes to a halt. In particular, if you begin the main work without sufficiently verifying known points, coordinate consistency can break down halfway through, resulting in the greatest loss of time.

A common problem in managing reference points is that, even when you know reference points exist, it is not clear which one to use. Even if multiple points are shown on the drawings, some are easier to verify in the field than others. Changes in the surrounding conditions can make them harder to find, and work vehicles or temporary structures can make them difficult to approach. If you have to start searching for reference points on site each time, the tempo for starting work is disrupted.

To prevent this problem, it is effective to organize the reference points to be used in advance with a prioritized order. If you decide on a second choice in case the first candidate cannot be used, decision-making on site will not be delayed. Furthermore, by keeping photos of the reference points, surrounding landmarks, and approach directions, even personnel entering the site for the first time can reach them in a short time. Designing operations to include not only the accuracy management of the reference points themselves but also their ease of finding will lead to time savings.

Also, rather than treating the reference-point check like an initial ritual, it is important to view it as the starting point that stabilizes the day’s work. Because RTK provides positions immediately, there are cases where the initial reference check is taken lightly. However, if that first check is insufficient, doubts will remain about all subsequent observations. When there is doubt, operators increase rechecks at key points and become overly cautious, which in turn wastes time. Establishing a state of confidence in a short time at the outset is ultimately faster.

One thing that makes reference point management even more effective is being strategic about how you use check points on site. In addition to formal known points, choosing a few markers to use for consistency checks during operations allows you to verify the status quickly after long-distance moves or when resuming work. This eliminates the need to start from scratch each time and helps you detect anomalies in the positioning state or in coordinates sooner.

Positional discrepancies become more critical the later they are discovered. If inconsistencies are only found when everything is checked at the end, much of that day’s work can be invalidated. Conversely, if the management of reference points is well organized, you can carry out the necessary and sufficient checks at the beginning, during, and at the end, and proceed without unnecessary doubt. This is not merely quality assurance; it is a mechanism to reduce re-surveys and keep to schedule.

At some sites, the handling of reference points is left to experienced staff. When which points to use and how much deviation warrants stopping work become tacit knowledge, efficiency drops the moment the person in charge changes. That is precisely why reference-point procedures should be formalized as site rules rather than treated as an individual’s skill. Creating a state in which anyone can follow them without hesitation ultimately leads to both time savings and consistent quality.

At sites where RTK work is fast, it’s not just that observations are good; the handling of reference points is also clear. Whether operations use a reference point as the starting point, start without hesitation, avoid unnecessary pauses midway, and can finish with confidence has a major impact on work time.

Specific Measure 3: Increase travel efficiency to reduce time spent on non-observational activities

When considering time savings from RTK, movement efficiency is surprisingly easy to overlook. On site, the time spent traveling to the next point, searching for a route, avoiding obstacles, or reconsidering the order of tasks can exceed the time spent measuring points. Especially on large sites or sites with significant elevation differences, poor movement planning alone can greatly increase the total man-hours.

Because RTK requires comparatively less constant attention to line of sight than a total station, it gives the impression that you can move around more freely. However, precisely because you can move freely, visiting points in nearest-first order without thinking often leads to back-and-forth trips or backtracking. A common on-site pattern is to observe targets in the order they catch your eye, then realize partway through that some points haven't been measured and have to return a long way. This repetition is less noticeable with RTK, where each point is measured quickly, and you can end up wasting time before you realize it.

To improve movement efficiency, it is effective to design the observation order in advance. Taking into account the arrangement of target points, vehicle circulation paths, allowable entry times, footing conditions, and the locations of slopes and structures, it is ideal to proceed in a flow as close to a continuous, one-stroke route as possible. Instead of deciding after arriving on site, deciding beforehand where to enter, where to turn back, and where to insert checks will greatly reduce walking time and hesitation.

It is also important to consciously make preparations for the next task while you are moving. Rather than heading to the next point and then searching for the target, confirm the position on the drawing as you move and note any nearby points of caution so you can begin observations immediately upon arrival. Conversely, an operation that only starts searching for the target after arrival causes small pauses at each point, which add up to a significant difference.

The way you carry equipment and accessories has a direct impact on movement efficiency. On site, carrying a pole, a terminal, a spare power supply, recording tools, and drawings separately will slow you down due to swapping items and repeatedly checking for things you might have left behind. By consolidating only the essentials and arranging them so they’re easy to access while walking, you can reduce small losses in transit. Especially when you need to observe many points in a single day, these minor differences in swapping items add up and affect the total time.

Moreover, travel efficiency is not just an issue within the site. The choice of vehicle parking positions, material storage areas, and entrances and exits is also important. If you park vehicles without being mindful of the starting and ending points, you may end up with long movements at the end. If, in the morning, you plan the layout with an eye on where you will ultimately withdraw from, you can avoid unnecessary back-and-forth during the tiring final stages.

In practice, wasted movement is harder to see than wasted observation. Observation errors are recorded, but repeatedly walking the same location rarely appears in the numbers and is therefore often overlooked as a target for improvement. However, if you truly want to shorten on-site work time, you need to address not only observation time but also reduce walking distance and the number of times workers stop.

The advantage of RTK is that it allows flexible work while moving widely around the site. To maximize that advantage, you need to design movement paths that take advantage of that freedom. When you can convert a state of being able to measure anywhere into a plan of where to go and in what order to move most quickly, RTK’s time-saving effect increases dramatically.

Specific Measure 4: Keep verification procedures concise and standardized to prevent rework

When aiming to shorten work time, you may be tempted to skip verification steps. However, in RTK operations, reducing the number of verifications is not the same as making verifications concise. In fact, the more ambiguous the required checks are on-site, the more operators will repeatedly verify out of anxiety, and as a result they lose time. What matters is not increasing the number of check items, but organizing procedures so that operators can gain assurance quickly.

First, the important thing is to clarify in writing what must be checked before proceeding. For example, you can decide on the minimum items to check on site, such as positioning status, correction reception status, the validity of coordinate values, whether the target point has been misidentified, and confirmation that recording is complete. If this is unclear, the depth of checks will vary between people, widening the gap between faster and slower workers. If the confirmation criteria are aligned, it becomes easier for anyone to work at the same pace.

Next, it is also important to organize the timing of checks. Checking everything to the same depth can actually become inefficient. If you separate what should be checked thoroughly at the start, what can be checked briefly in the middle, and what should be rechecked at milestones, you can spend time only where it is needed. Rather than always conducting checks at full effort, it's important to place them within the flow of work.

Also, the method for checking records directly affects time savings. On site, mistakes such as points you thought were measured not being saved, point names being shifted, or remarks being omitted tend to occur. If these mistakes are discovered after leaving the site they become very troublesome and can force a revisit. That’s why record checks are essential, but inspecting everything too deeply every time takes too much time. Deciding on a quick verification order you can run through in a few seconds—point name, saved status, presence of abnormal values, etc.—lets you maintain reliability without slowing your pace.

Organizing screen displays and input fields is also effective for simplifying verification procedures. Screens with a lot of unnecessary information slow down decision-making. Arranging frequently used items so they are immediately visible, adopting naming rules that prevent confusion on site, and setting up categories that are easy to select when recording will shorten the operation time per point. If operations are complicated, operators become more cautious to avoid mistakes, and as a result the processing of each item becomes more burdensome.

Furthermore, standardizing verification procedures also helps with isolating issues during troubleshooting. When something feels off on site, if the order in which checks should be performed is decided, you can identify the cause more quickly. Conversely, if you check things haphazardly as they occur to you, only time passes and your judgment wavers. Worksites that have a verification flow enabling rapid situation assessment are resilient not only during normal operations but also when abnormalities occur.

A common misconception is that reducing checks will save time. However, in practice, rework caused by insufficient checking is a far heavier burden. What’s important is to ensure checks that are neither excessive nor insufficient, performed in the same order each time and completed quickly. This is not only for work quality but also a measure to prevent rework and protect the overall time.

A site that is fast with RTK isn't one that skips verifications. It's one that can complete the necessary checks quickly and reliably. Because the sequence of measuring, checking, recording, and moving on is smooth and decision-making involves little hesitation, it ultimately becomes faster.

Specific Measure 5: Streamline team operations to eliminate time spent waiting for decisions

To genuinely shorten RTK work time, it is essential not only to rely on individual operating skills but also to design operations at the team level. On site, even if the person handling the equipment is excellent, poor coordination with other members frequently leads to waits for decisions and confirmations. Especially on sites where multiple people work together, if it is unclear who decides what, who checks what, and who keeps the records, work will stall at various points.

First, what needs to be reviewed is clarifying the division of roles. Roles such as observer, target verifier, recording assistant, and progress manager do not necessarily require a large number of people, but the functions needed on site should be considered separately. For example, if the observer has to look at the drawings each time to find the target point, choose the record name, and decide the sequence of operations, they will have too many decisions to handle alone and the pace will slow. By separating roles, the observer can concentrate on measuring, and the overall speed will increase.

Next, it is important to always conduct a brief alignment before starting work. If the day's scope, priority areas, reference points, points to note, and completion criteria are shared, there will be fewer detailed confirmations while on site. Conversely, without this sharing, small decisions—such as whether to proceed, whether to postpone, or how far to measure—will need to be consulted each time, causing waiting time.

One of the most effective practices in team operations is to establish decision-making criteria in advance. If you define how much of a discrepancy warrants rechecking, under which conditions work should be halted, what can be corrected on-site and what should be taken back for judgment, those responsible will be less likely to hesitate. Operations that require confirmation from a supervisor or an experienced person every time inevitably slow down on-site work.

Also, rules for call-outs are surprisingly important. At milestones such as target confirmation, observation completion, save confirmation, and movement to the next point, simply using short, standardized phrases makes coordination smoother. On site, common cues are faster and more accurate than long explanations. Especially in noisy environments or when working while moving, simplifying information transmission directly leads to time savings.

Furthermore, when there is a large difference in work speed within a team, it is necessary to devise ways to align the workflow rather than accommodate each individual. If faster people move ahead too far, checks and record-keeping can't keep up and waiting occurs elsewhere. Conversely, if everyone can operate under common procedures, the site will be consistently fast even without standout individual skills. Achieving time savings is more reproducible by raising the average speed of everyone than by relying on the abilities of a few.

Organizing team operations is not the same as adding more people. In fact, the smaller the team, the more roles overlap, and the quality of operations directly determines how time is used. If it is decided who is responsible for what, in what order people should act, and who will make decisions during abnormal situations, even a small team can operate very quickly.

RTK is a technology that is easy for a single person to handle, but on sites involving multiple people, how well the team coordinates has a major impact on work time. If you can eliminate time spent waiting for decisions, confirmations, and instructions, you can achieve time savings greater than those from faster observations. It is important not to attribute slow site progress solely to individual proficiency, but to review it as a team workflow.

Summary

To shorten work time with RTK, it is essential not only to leverage the equipment’s performance but also to streamline the field operations themselves. When thinking about saving time, people tend to focus on ways to speed up observations, but in reality many losses lurk in peripheral processes such as preparation, reference setup, movement, verification, and coordination. If those areas are not reviewed, introducing RTK alone is unlikely to deliver the expected benefits.

The five specific measures introduced here may appear to be independent, but in reality they are closely connected. Because the preparations are in place, reference point checks can begin smoothly; because the standards are clear, it becomes less likely to get lost while moving. If the movement flow is good, checks won't become excessive, and if the verification procedures are standardized, team coordination will be faster. In short, rather than improving any single measure alone, organizing them as an overall flow produces a greater time-saving effect.

To truly shorten time on-site, rather than trying to move faster, it is more effective to adopt the mindset of reducing the causes of stoppages. Don’t be stopped by insufficient preparation, unclear standards, uncertainty about the sequence, excessive checks, or poor coordination. If you can create that state, work will naturally become faster without forcing haste. And that speed will not be speed achieved at the expense of quality, but a stable, reproducible speed.

RTK is a method that, when operated correctly, can greatly increase on-site productivity. However, its effectiveness is not determined by equipment acquisition alone. Only by standardizing pre-site preparations, organizing reference point operations, planning movement flows, simplifying verification procedures, and aligning the roles of the entire team can genuine time savings be realized.

If you're going to work on operational improvements, I recommend first listing where waiting time occurs at your site. If you can determine whether work stops before starting, pauses during movement between locations, halts for checks, or is held up by coordination, the priorities for improvement will become clear. The key to reducing working time with RTK is not just the measuring technology itself but creating operations that keep the entire site running.
