Surveying has long been a cornerstone of construction, land development, and engineering. For years, traditional tools like manual total stations, levels, and theodolites were the go-to equipment for surveyors. These instruments offered precision and reliability but came with limitations, particularly in terms of speed and efficiency. In recent years, GPS and GNSS (Global Navigation Satellite System) technologies, including RTK (Real-Time Kinematic) GPS systems, have transformed the landscape of surveying.
At Benchmark, we’ve helped surveyors all across North America transition from conventional tools to state-of-the-art GPS/GNSS equipment. For those who are still considering the switch, this article delves into the advantages of RTK GPS, compares it to traditional survey methods, and highlights how surveyors like Jim have successfully made the leap.

Traditional surveying relies on tools that have stood the test of time. Instruments such as manual total stations and levels are staples of the profession. I am sure most of you have had the pleasure of using them through school or as the main instrument in your toolbox. These (overwhelmingly optical) instruments are particularly effective for measuring angles and distances, performing boundary surveys, and setting out points for construction. They are widely regarded for their precision and reliability, especially in experienced hands.
Despite their strengths, traditional surveying methods are not without their drawbacks. Setting up a total station or leveling equipment can be time-consuming, particularly on large or complex sites. Moreover, these methods often require multiple personnel, with one operator handling the instrument while another sets targets or collects measurements. Environmental factors, such as uneven terrain, dense vegetation, or urban structures, can also interfere with line-of-sight measurements, further complicating the process. Traversing through rough terrain, and cutting sight lines can dramatically slow down surveys.
RTK GPS systems have brought a revolutionary shift to the surveying profession. Unlike traditional methods, RTK GPS uses satellite data to provide real-time corrections, enabling centimeter-level accuracy in positioning. By integrating satellite signals with a base station and a rover unit, surveyors can achieve precise results quickly and efficiently.
One of the most significant advantages of RTK GPS is the speed it offers. Surveying tasks that might take hours with traditional methods can often be completed in minutes. Additionally, the technology simplifies workflows, reducing the need for manual calculations and enabling a single operator to manage tasks independently. RTK GPS is also incredibly versatile, excelling in a variety of applications, from boundary surveys and topographic mapping to construction staking and infrastructure monitoring.
With RTK, users do not need to rely on line of sight to perform their measurements. By using communication methods that broadcast corrections over 10s of kilometers surveyors can cover much larger areas much faster than they ever would with total stations. This also means you avoid the issues that come with traversing, including the compounding of error.
Of course, RTK GPS systems come with their challenges. The initial investment is higher compared to some traditional tools, like manual total stations and levels, but are comparable to the more popular robotic total stations. and there is a learning curve for surveyors who are new to the technology. Additionally, satellite signals can be obstructed in areas with heavy tree cover or urban canyons, potentially affecting performance. Although with the latest signals and technology, units like the Hemisphere S631 or Trimble R980 are capable of surveying even in dense canopy.
For surveyors who have spent their careers using manual equipment, the idea of transitioning to GPS technology can be intimidating. Jim, one of our clients from this summer, is a prime example of how this transition can be smoother than expected. A seasoned professional with years of experience using manual total stations and levels, Jim knew his tools well but found them increasingly limiting. He wanted to adopt GPS technology to improve his efficiency but had no prior experience with it.
When Jim purchased his RTK GPS system from me, he was scared about the complexity of the new equipment and how he was going to learn how to use it. However, within three hours of receiving the gear, he was ready to begin surveying confidently. This quick turnaround was made possible by Benchmark’s three-tiered approach to training and support.
First, we sent Jim had our online training academy, Survey-Assistant.com, a 24/7 resource designed to help surveyors learn at their own pace. Next, we got him seated in our live Zoom training sessions, where he could interact with Nolan and get real-time answers to his questions. Finally, our on-demand technical support team was available to assist with any challenges he faced in the field. Together, these resources ensured that Jim could integrate RTK GPS into his workflow seamlessly.
Today, Jim is working faster and more efficiently than ever. Operating in a hot climate, he takes advantage of the early mornings to complete his surveys, leveraging the speed and ease of his GPS system to maximize productivity.
The transition from traditional methods to RTK GPS represents more than just a change in tools—it’s a complete evolution in how surveyors approach their work. Traditional equipment, while dependable, is often labor-intensive and time-consuming. In contrast, RTK GPS streamlines workflows, reduces setup times, and allows surveyors to cover larger areas with greater efficiency.
The independence offered by RTK GPS is another major advantage. Tasks that might require a team of two or more people with traditional equipment can often be handled by a single operator using GPS. This not only reduces labor costs but also allows surveyors to take on more projects in less time, enhancing their overall profitability.
While traditional methods may have a lower upfront cost, the long-term benefits of RTK GPS make it a cost-effective choice. Faster project completion times, reduced manpower requirements, and minimized errors contribute to significant savings over time. For surveyors who are willing to invest in their future, the advantages of RTK GPS far outweigh the initial expenses.
Making the switch to RTK GPS involves more than just acquiring new equipment. It requires learning new workflows and ensuring the technology integrates seamlessly into daily operations. At Benchmark, we understand these challenges and are committed to supporting surveyors every step of the way.
