1 Different Types of GNSS Correction Service

RTK: Real Time Kinematic (RTK) is a technique used to increase the accuracy of GNSS positions using a fixed base station, that wirelessly sends out correctional data to a moving receiver. Any application that requires centimeter-level accuracy is likely to benefit from having RTK as the source of correctional data. Typical applications include ADAS testing, autonomous vehicle validation, ground truth measurement, and path following.

RTK-PPP: PPP-RTK is a high-precision positioning technology based on the state domain (SSR). PPP-RTK technology is more advanced and is a combination of PPP (precision single point positioning) and RTK (real-time dynamic positioning) technologies. It has the advantages of both, including high accuracy, short convergence time, and wide coverage, Features include short initialization time.

PPP: Precision Point Positioning (PPP) is a Global Navigation Satellite System (GNSS) positioning method that can calculate very precise positions, with errors as small as a few centimeters under good conditions. The user uses a single GNSS receiver to achieve global precision absolute Positioning technology. PPP has two main advantages: First, the broadcast method can simplify the user end; second, it uses far fewer base stations than RTK, which can maintain global consistency in positioning accuracy. Since atmospheric errors are not included in PPP corrections, only a lower accuracy level can be achieved with this method, and a longer initialization time is expected, up to 20-30 min, which may not be practical for some applications. PPP has been traditionally used in the maritime industry and today has expanded to various land applications such as agriculture, as a convenient way to get global GNSS corrections.

2 Global GNSS Correction Service Value by Types (2018-2023)

In 2018, the RTK segment led with a revenue of $171.00 million, showcasing its dominance in providing high-precision positioning solutions, particularly in sectors requiring centimeter-level accuracy such as construction, surveying, and precision agriculture. The PPP segment followed with $152.92 million, highlighting its utility in applications where global coverage is needed with minimal infrastructure. The RTK-PPP segment, being a relatively newer technology, held a revenue of $83.41 million, although it is in the initial adoption phase, with significant potential for growth.

Fast forward to 2023, the revenues for these segments have shifted, the RTK segment reached $255.82 million, maintaining its lead with a substantial increase from 2018. The PPP segment grew to $215.08 million, underscoring its cost-effectiveness and global reach, which are crucial for large-scale projects and international operations. The RTK-PPP segment reached $135.46 million, a significant leap from its 2018 figures, presenting the market’s increasing preference for services that combine the strengths of both RTK and PPP.

Table Global GNSS Correction Service Value (M USD) by Types (2018-2023)

RTK consistently holds the largest share, starting just below 42% in 2018 and showing minimal fluctuation, with a slight increase by 2023 to 42.19%. RTK-PPP, on the other hand, shows a more pronounced decline, starting at around 20.48% in 2018 and decreasing to just around 22.34% in 2023. This suggests a diminishing proportion relative to the other categories.

PPP maintains a stable presence as the second-largest category, with its share slightly decreasing from 37.54% in 2018 to 35.47% in 2023. The overall trend indicates a slight shift in the balance among the three categories, with RTK and PPP remaining the dominant forces, while RTK-PPP’s share is on a downward trajectory.

4 Different Applications of GNSS Correction Service

The GNSS Correction Service market is segmented into various applications that leverage the precision and reliability of Global Navigation Satellite System (GNSS) corrections to enhance operational efficiency, safety, and accuracy across different industries, such as agriculture, construction, GIS and mapping, marine, etc.

Table Different Applications of GNSS Correction Service

Applications	Description
Agriculture	Using GNSS correction services can improve the accuracy of GNSS technology, and high-precision GNSS is widely used in agriculture. A representative application in the field of precision agriculture is agricultural machinery automatic driving systems. After the agricultural machinery’s automatic driving system is combined with high-precision GNSS navigation technology, the agricultural machinery can automatically drive smoothly and accurately according to the preset route, ensuring the quality of the operation.
Construction	There have always been many pain points in the construction site of the construction industry, such as chaotic safety management and many hidden dangers of accidents. It is difficult for managers to fully grasp the progress of the work. Moreover, the larger the scale of project construction, the more likely it is that loopholes that are complex in process and difficult to monitor and manage will occur. This is becoming more and more common. Under more refined management, engineering construction requires more convenient and timely monitoring methods, and these methods are inseparable from high-precision GNSS systems. Therefore, the application of GNSS correction services can greatly improve the current situation of the construction industry. Using GNSS correction services can provide the construction industry with a high-performance and economical solution for high-precision centimeter-level tracking applications. While maintaining low power consumption, it also has excellent integrated positioning performance, enabling accurate positioning even in harsh environments. High-precision GNSS is an ideal choice for smart engineering, inspection, and other application fields in the construction industry.
GIS and Mapping	High-precision GNSS technology provides a reliable data source for ground measurement and mapping. By integrating GNSS receivers with surveying instruments, surveyors are able to accurately measure the coordinates of ground control points. These control points can be used to measure the location and shape of ground objects to generate maps, make 3D models, and perform land management. Compared with traditional measurement methods, GNSS technology using correction services can greatly improve measurement efficiency and accuracy. GNSS technology is also widely used in the GIS field. First, GNSS technology provides the foundation for navigation and positioning services. Devices such as mobile phones, vehicle navigators, and logistics management systems can all use GNSS receivers to determine their location and provide corresponding navigation information. In terms of urban navigation and traffic management, the application of GNSS technology has become common, bringing more convenience to people’s travels. In addition, high-precision GNSS technology plays an important role in disaster monitoring and emergency management. By monitoring crustal movement and seismic activity, GNSS receivers can provide accurate earthquake warnings and surface deformation data. These data are very important for scientists to study the mechanism of earthquakes, predict seismic activity, and take corresponding emergency measures.
Marine	In the marine field, high-precision GNSS applications also play an important role. Through high-precision GNSS positioning analysis, the marine environment can be monitored in real-time, changes in the marine ecosystem can be understood, and marine disasters can be predicted to assist decision-making. High-precision GNSS applications can also provide data support in fields such as fishery and shipping. For example, ships can use GNSS to determine their position, speed, heading, and other information to improve ship safety and transportation efficiency. In addition, GNSS can also provide services such as marine meteorological forecasts and marine environment monitoring, so GNSS correction services are also essential in the future development of the ocean field.
