However, when tasked with selecting the most suitable tool to ensure accuracy, professionals often find themselves at a pivotal juncture, confronting a crucial question: Should they persist with the familiar yet limited capabilities of traditional GPS technology, or should they explore the possibilities of a more advanced option like the SMA20 RTK? This decision is far from straightforward, as the choice between these technologies can significantly influence not only the accuracy but also the overall efficiency and success of a project. In this article, we unpack the complexities of the SMA20 RTK, contrasting it with conventional GPS systems to explore its unique advantages and assess why it may be the optimal solution for addressing the intricate demands of your projects.
What is SMA20 RTK?
The SMA20 RTK is a highly versatile and lightweight GNSS (Global Navigation Satellite System) receiver, meticulously engineered to deliver precise positioning even in the most demanding environments. Unlike traditional GPS, which generally offers meter-level accuracy, the SMA20 RTK employs Real-Time Kinematic (RTK) technology, enabling users to achieve centimeter-level precision. Furthermore, the device is outfitted with an Inertial Measurement Unit (IMU), a sophisticated feature that eliminates the need for manual leveling of the receiver. This enhancement significantly simplifies operations, making the SMA20 RTK particularly valuable for time-sensitive projects that demand both speed and accuracy.
RTK Technology for Enhanced Accuracy
The key to the SMA20 RTK’s superiority lies in its ability to provide real-time positional corrections, allowing users to reach unprecedented levels of accuracy within centimeters. This level of precision is especially crucial in fields like land surveying, where even the slightest measurement discrepancies can result in costly errors. In contrast, conventional GPS, with its typical accuracy range of a few meters, often falls short in projects that require pinpoint precision.
Moreover, the integration of the IMU into the SMA20 RTK elevates its accuracy to a new standard. With the IMU’s support for tilt surveys, users no longer need to meticulously maintain a level device during measurements. This feature not only improves efficiency but also adds a layer of convenience, particularly in challenging terrains where maintaining perfect leveling can be difficult.
Performance in Challenging Environments
The SMA20 RTK excels where traditional GPS often falters, particularly in environments where signal interference is common. Whether operating in urban canyons, dense forests, or remote locations with poor signal coverage, the SMA20 RTK performs consistently thanks to its global signal reach. These features make it an ideal choice for projects that are located in hard-to-access areas, where conventional GPS might struggle with weak or obstructed signals.
SMA20 RTK vs. Traditional GPS
When comparing the SMA20 RTK to traditional GPS, several distinct differences emerge that can substantially affect the outcome of your project. Although both systems depend on satellite signals, the advanced technology behind the SMA20 RTK offers superior accuracy and flexibility, making it the better choice for tasks that require high precision.
Precision and Accuracy
One of the most obvious differences between SMA20 RTK and traditional GPS lies in the accuracy they provide. Traditional GPS receivers typically offer meter-level accuracy, which might suffice for general navigation or low-stakes activities. However, in sectors such as construction, precision agriculture, and land surveying, where exact measurements are paramount, the centimeter-level accuracy provided by SMA20 RTK is indispensable.
For tasks that do not require extreme precision, such as casual navigation or basic location tracking, traditional GPS may suffice. However, projects involving infrastructure layout, property boundaries, or complex site planning demand the enhanced accuracy that only the SMA20 RTK can provide.
Efficiency and User Convenience
Traditional GPS systems often require users to monitor and adjust the bubble level to maintain accuracy during measurements, a process that can be tedious and time-consuming, especially in uneven or rugged environments. In contrast, the SMA20 RTK, equipped with its IMU, removes this hassle entirely. By enabling tilt surveys, the SMA20 RTK allows users to take measurements without needing to worry about maintaining a perfectly level device, significantly improving workflow efficiency, reducing the potential for human error, and ultimately saving valuable time.
Additionally, the SMA20 RTK’s ability to perform optimally in difficult environments—whether in dense urban areas or rural regions with weak signals—gives it a distinct edge over traditional GPS systems, which often struggle in such conditions.
PPK Characteristics of SMA20 RTK
While the SMA20 RTK is primarily recognized for its real-time accuracy through RTK technology, it also includes Post-Processed Kinematic (PPK) capabilities. This feature is particularly useful for projects requiring high precision in areas where real-time signal coverage may be limited or unreliable.
High-Precision Positioning via PPK
One of the key advantages of PPK technology is its ability to compute relative positions with centimeter-level accuracy by post-processing satellite carrier phase data from both reference and mobile stations. This capability allows the SMA20 RTK to deliver highly accurate results, even in locations where real-time data links are unavailable.
Traditional GPS, by comparison, does not offer this level of precision, as it depends entirely on real-time signals, which are susceptible to degradation in challenging environments. PPK technology, on the other hand, ensures accurate results by processing data after collection, making it an ideal solution for environments where real-time precision may be difficult to achieve.
Flexibility in Difficult Terrains
PPK technology also provides greater flexibility and adaptability compared to traditional GPS. Since PPK does not require a real-time data link, it is particularly well-suited for use in environments where signal blockages or poor infrastructure impede connectivity, such as urban canyons, forests, or mountainous regions. In these situations, traditional GPS often falls short, while the SMA20 RTK equipped with PPK technology proves to be the more reliable and efficient choice.
Another significant advantage of PPK is its ability to operate independently of real-time data connections, giving users more freedom and flexibility in remote locations. This ensures that highly accurate measurements can be obtained even in areas where continuous satellite communication is difficult or impossible.
Data Integrity and Robustness
PPK technology also excels in its ability to handle GNSS data collected during operations, making it robust against temporary signal loss or errors. Traditional GPS lacks this robustness, as it relies on uninterrupted real-time signals to maintain accuracy. PPK technology, in contrast, processes data post-collection, ensuring that any temporary signal interruptions do not compromise the final results.
PPK’s ability to safeguard against data loss makes it especially well-suited for long-distance projects, such as highway construction, railroad planning, or pipeline installations. While traditional GPS systems are often limited by communication range, the SMA20 RTK’s PPK capabilities enable it to operate over vast areas without risking data loss.

The high accuracy of the SMA20 RTK ensures that tasks such as planting, spraying, and harvesting are completed with pinpoint accuracy, leading to increased efficiency and profitability. Traditional GPS, with its lower precision, may not meet the needs of modern precision farming techniques.
Construction and Surveying
Construction projects require exact measurements to avoid costly errors. The centimeter-level accuracy of the SMA20 RTK is invaluable for tasks such as laying building foundations, measuring property boundaries, and ensuring that structures are properly aligned. Surveyors also benefit from the device’s tilt survey feature, which eliminates the need for constant leveling and speeds up operations while enhancing accuracy.
Urban Planning and Infrastructure
For urban planners and engineers, precise data is critical to designing and executing infrastructure projects. The SMA20 RTK’s ability to function seamlessly in dense urban environments, where signal interference is common, makes it an ideal tool for tasks such as mapping roads, planning utility networks, or designing transportation systems.
