Are RTK communication fees expensive? Breakdown of running costs into 4 items

When starting to use RTK on-site, many field operators are concerned about communication fees. Because there is an impression that continuous communication is required to obtain high-precision positioning information, many people worry that costs will increase the longer they use it. In particular, at sites that have so far operated mainly with standalone positioning or conventional surveying equipment, the expected monthly costs after introducing RTK and whether unforeseen communication-related burdens will arise become important factors in decision-making.

However, the operating cost of RTK is not determined solely by communication-line usage. To achieve stable positioning on site, it is necessary to consider how correction information is obtained, device management, and operational systems to prevent work stoppages. Conversely, if you judge whether a solution is expensive or cheap based only on communication fees, you may misjudge the actual operational burden. Even if communication costs themselves are kept low, frequent connection problems that increase re-measurements or return trips can make the overall operation on site more costly.

In this article, we outline the reasons why RTK communication fees often feel expensive, and then break down the running costs you should actually look at into four items. We present this in a clear, practical manner to be helpful both for those considering adoption and for those already using RTK who want to reassess their cost expectations.

Reasons why RTK communication fees are often perceived as high

RTK communication fees tend to be perceived as high because communication is positioned almost as a precondition for achieving positioning itself. With ordinary use of location information, a somewhat unstable connection often does not cause major problems. However, with RTK, positioning is frequently maintained while continuously receiving correction information, so poor communication directly affects accuracy and work efficiency. For that reason, it is often regarded not merely as an issue of a service contract but as a factor that can determine on-site productivity.

Also, the fact that the term "communication fees" is used to lump together multiple costs is another source of misunderstanding. In practice, costs such as line contract fees, the burden associated with using correction information, the effort of device management, and operational costs to guard against connection failures are mixed together. These items should ideally be considered separately, but on-site they occur as a single package, so people tend to perceive the communication fees as being high when viewed collectively.

Furthermore, perceived RTK costs vary depending on how often it is used. The same system feels different when used every day on a large site versus used briefly only when needed. On sites with low usage frequency, the fixed burden of maintaining communications appears relatively heavy. Conversely, on sites with high usage frequency, whether positioning is stable and can shorten working hours becomes more important than a moderate communication cost. In other words, RTK communication fees should be evaluated not just by their amount but by the balance with the benefits gained on site.

Another important point is that the amount of data traffic itself is not necessarily extremely large. In many field sites, large-capacity video or images are not constantly sent and received. The correction information exchanged by RTK is not necessarily heavier than typical business communications, and what tends to become a problem is continuity and stability rather than capacity. In other words, if you imagine communication costs based solely on the sheer amount of data, you may be off the mark. To judge whether costs are high, it is important to check what must be maintained for stable operation rather than focusing on the data volume.

Running Cost 1: Burden of Maintaining Communication Lines

One of the first things to check about RTK running costs is the burden of maintaining the communication lines. This is the clearest item and the part that on-site staff are most likely to think of first when they hear “communication charges.” In RTK, it is common for the rover (mobile unit) to use communications to receive correction information, so the connection needs to be kept in a stable, usable state for that purpose.

What is important here is that the load on the communication line is not determined solely by whether you have a contract. The way you need to think about required stability changes depending on whether the site is in a mountainous area, an urban area, a development site, or an environment with many obstacles. It's important not only whether the signal reaches, but whether the connection stays stable while moving and whether correction information can be received continuously during working hours. In locations with weak radio signals, the same RTK operation can feel substantially more burdensome in practice.

Also, at sites where multiple people use them simultaneously, the way you think about communication lines changes. Whether you give each person an individual communication method or cover needs with shared terminals affects ease of management and on-site flexibility. Providing individual connections makes operations easier, but increases what you have to manage. Using shared devices makes organization simpler, but makes equipment handovers and configuration errors more likely. In other words, the cost of communication lines should be evaluated not just by the contract itself, but including how they are allocated and maintained on site.

Furthermore, communication lines have the characteristic that problems can be hard to detect under normal conditions. Even if things go smoothly shortly after deployment, when the number of users increases during busy periods, the site changes, or connection conditions vary by season or time of day, differences in stability may emerge. At that point, simply having provisioned a line is not enough; what matters is whether operations are set up to ensure stable usability. If you maintain a line but it is often unusable on site, then—even if the apparent communication charges are low—you should consider it costly in practical terms.

When considering RTK communication lines, it is important to prioritize continuity over capacity, on-site suitability over contract terms, and the impact on the overall workflow over individual costs. Even if the load on the communication line appears small at first glance, because it is the foundation that affects positioning stability, neglecting it will later rebound as a burden on site.

Running Cost 2: The Burden of Continuing to Use Corrected Information

In RTK operations, simply having a communications link is not enough. To achieve high-precision positioning, a mechanism that can continuously receive correction information is required. Therefore, as the second running cost, you need to separately consider the burden of maintaining access to correction information.

In practice, when deploying RTK the focus often goes to the hardware, but in reality securing correction information is the key to continued operation. If correction information cannot be obtained reliably, no matter how high-performing the equipment's receiver is, you will not achieve the expected accuracy in the field. Therefore, methods for obtaining correction information and the operational conditions should be regarded as ongoing burdens separate from communication fees.

The reason this burden is easily overlooked is that the correction information is not something visible. Equipment and terminals are physically present, but the correction information exists as a service or an operational framework. As a result, even if it is understood at the time of contracting, after deployment the on-site team may not fully grasp the system. For example, constraints on usable areas, the need to confirm connection conditions, or variations in stability depending on the site—points that would not be problematic if known in advance can surface as burdens after operations begin.

Moreover, the burden of continuously using correction information is not simply whether it can be received. Differences also arise depending on whether on-site personnel understand when a fixed solution is likely to be obtained and under what conditions solutions become unstable. If the system is operated without understanding how it works, situations are more likely to occur where accuracy fails to stabilize despite being connected, or results vary even though corrections are being received. Each time verification tasks and re-measurements increase, hidden running costs accumulate.

To properly assess the burden associated with correction information, it is important before deployment to check whether it fits the area of use and work hours, how much on-site connection verification can be simplified, and whether the personnel can easily understand the system. In other words, the burden of correction information is a matter of ease of operation beyond the communications; if this is overlooked, simply cutting communication fees will not make things easier in the field.

To keep RTK stable and reliable over the long term, it is important not only to be able to continuously receive correction information but also to be able to easily reproduce that state on site. Considering the running costs of correction information, including ease of operation — for example, that procedures do not change significantly when the site changes and that decision criteria remain consistent even if personnel change — will ultimately be the quickest way to reduce unnecessary burdens.

Running Costs 3: Burden of Maintaining Devices and On-site Operations

The third element to consider in RTK running costs is the burden of maintaining the terminals and on-site operations. This may seem somewhat removed from the term "communication fees," but in reality it is a prerequisite for using communications stably. If the condition of the terminals is unstable, the system becomes difficult to use in the field even if the communication environment and correction information are fine.

The first thing to be aware of is that RTK operations cannot be completed by desk-side settings alone. On site, multiple procedures overlap, such as checking the device’s charge level, communication settings, position information, monitoring reception status, and verifying app and device connections. If these depend on the individual operator’s experience, usage will vary each time personnel change, and as a result the time spent on re-checks increases. These time burdens do not show up in the books as communication fees, but they certainly exist as operational costs.

A typical example of when the burden of device management increases is a complex equipment configuration. When receivers, terminals, communication equipment, and power supply units are separated, each must be checked, and preparations before going on site take longer. Even just isolating where the connection problem lies can be time-consuming, delaying the start of work. Before worrying about whether communication fees are high, you need to assess how simple the preparation and recovery required to establish communication are; otherwise you risk misjudging the actual burden.

Moreover, the burden of devices and on-site operations accumulates through day-to-day minor tasks. For example, if connection checks before work take time each time, setup methods vary by operator, or device handovers and reconnections on site are frequent, those small losses per instance add up to a significant loss over a month. RTK is a technology that can streamline work through improved accuracy, but if operational procedures are cumbersome, that advantage will be offset.

Moreover, the training burden cannot be overlooked. Even if administrators and more knowledgeable staff understand the settings during the initial deployment, stable operation across the entire site requires that anyone be able to use the system to a certain standard. If operating procedures are complex and responses to communication problems depend on specific individuals, inquiries and confirmations will arise every time in the field, making it easy for day-to-day operations to come to a halt. This stagnation is a hidden running cost.

Therefore, in RTK terminal operations you should prioritize not only achieving accuracy but also how easy the units are to prepare, how portable they are, how easy they are to reconnect, and whether they help prevent operator confusion. Even when communication fees are similar, a system with well-organized terminal operations will, as a result, reduce on-site burdens and make it easier to lower total costs. For the continued use of RTK, it is important not to treat communications and terminal operations separately, but to view them as a single operational framework.

Running cost 4 The burden of preventing work stoppage and re-measurements

When considering the running costs of RTK, the most easily overlooked yet operationally significant factor is the burden of preventing work stoppages and re-surveys. At many sites, interruptions caused by unstable communications or positioning are a heavier problem than the communication charges themselves.

RTK is highly efficient when positioning is stable. However, if correction information is interrupted, communication conditions worsen, or connection checks take time, the workflow quickly breaks down. As a result, on-site idle time occurs, re-measurements for verification increase, and the effects spread to subsequent processes. Because people and equipment are moving on site, even brief stoppages have a significant impact. Even if you only save on communication costs, if such stoppages increase the overall operation becomes rather inefficient.

The burden of re-measurement is not just the time it takes to measure again. It expands to surrounding tasks such as cross-checking with previous data, identifying causes, sharing with stakeholders, and adjusting workflows. In particular, for work where the reliability of coordinates directly serves as the basis for judgment—such as construction management and as-built verification—even a single inconsistency requires careful confirmation. The burden that arises here does not appear in the details of communication contracts, but in reality it represents a significant running cost.

Also, preventing work stoppages or re-measurements requires investment in advance. Before entering the site, you should anticipate communication conditions, check for obstructions and the radio environment, and consider alternative measures as necessary. This may seem tedious, but it will ultimately reduce the burden compared with stopping on site with nothing prepared. The higher the accuracy of RTK, the more noticeable any lack of preparation becomes.

Furthermore, the psychological burden on operators cannot be ignored. A system that they use each time with anxiety—worrying whether it will connect today or whether positioning will be stable—will struggle to take root in the field. Conversely, if they have a sense that it will work reliably, operators are more likely to use RTK as an everyday tool. This difference is large enough to affect the benefits of adoption. In other words, the burden of preventing re-measurements and stoppages is not only technical but also a burden to support operational reliability.

When introducing RTK, attention tends to focus on apparent communication fees, but what you should really compare is how much you have to strain operations to avoid halting work on site. If you can achieve stable positioning, allow staff to operate without hesitation, and make recovery from problems easy, then even with some ongoing costs it can be reasonable overall. Conversely, if you only cut superficial costs but stoppages and re-surveys occur frequently, that is costly to operate.

How to Properly Evaluate RTK Running Costs

As we've seen, when considering RTK communication fees, it is important not to assess them by looking only at the communication line. In practice, running costs consist of maintenance of the communication line, continued use of correction information, management of devices and the operational setup, and preparations to prevent work stoppages or re-surveys. Therefore, whether communication fees are high should be answered not by a simple price comparison but from the perspective of what can be reduced across the entire site.

First, it is important to distinguish between burdens that occur on a fixed basis and those that increase or decrease depending on each site. By separating items that recur monthly, those that change according to usage frequency, and those that only increase during incidents, it becomes easier to see which burdens are truly heavy for your company’s sites.

At sites with high usage frequency, the time-saving effects of stable operations are large, so recurring costs are easier to absorb. On the other hand, at sites with limited usage frequency, it is important to have a system that can operate efficiently without waste.

Next, the criterion should be whether it can be used on site without hesitation, not merely whether the connection can be established. Even if a system is theoretically usable, if it requires checking settings every time and its accuracy varies depending on the operator, it is not suited to long-term operation. RTK only delivers value when it can be handled as a practical tool on site. Therefore, the assessment of communication fees should be based not on low cost but on whether there is assurance of day-to-day ease of use and stability.

Furthermore, at the time of deployment, it is important not to treat equipment selection and operational design as separate matters. If you choose solely based on receiver performance and accuracy, you may face difficulties in actual communications and on-site management. Conversely, if you select with the entire on-site workflow in mind, it becomes easier to reduce preparation time, training burden, and the risk of re-measurement. For RTK, running costs are easier to lower by choosing an operationally convenient setup from the start than by trying to save later.

From the perspective of field personnel, when assessing whether communication fees are high, it’s more practical not to focus on the monthly cost itself but to verify what that cost secures. If elements such as stable positioning, smooth startup, ease of operator proficiency, and minimal on-site downtime are in place, RTK becomes not merely an expense but a foundation that supports work quality and productivity.

Summary

At first glance RTK communication fees may seem high, but in reality they should not be judged solely by the cost of the communication line. To use RTK reliably in the field, it is important to organize running costs from four perspectives: maintenance of the communication line, continued use of correction information, management of terminals and operational systems, and preparations to prevent work stoppages or re-measurement. By separating these four items, it becomes easier to see what is a fixed burden and what can be reduced through operational choices.

What matters to field practitioners is not a superficial comparison of whether communication charges are high or low, but whether the system can be used on site without hesitation, is unlikely to stop, and results in minimal rework. With RTK, the higher the accuracy, the more directly the quality of operations affects the outcomes. That is why it is essential to judge not only by apparent cost but also by the overall efficiency and stability of the site.

If, when introducing or reviewing RTK, you want to simplify communication and operational burdens as much as possible, it is important to consider not just the device itself but also how easy it is to use on site. If you want to make daily positioning work more accessible and make it easier to handle high-precision location information within the flow of operations, it can be effective to consider options that prioritize on-site usability, such as LRTK (iPhone-mounted GNSS high-precision positioning device). Rather than focusing only on communication fees, looking at how to optimize the overall running costs of the site will make the benefits of RTK implementation clearer.
