Satellite-based GNSS Augmentation System Market Size

Satellite-based GNSS Augmentation System Market size was over USD 10.66 Billion in 2023 and is set to cross USD 24.47 Billion by the end of 2036, witnessing more than 6.6% CAGR during the forecast period i.e., between 2024-2036. In the year 2024, the industry size of satellite-based gnss augmentation system is estimated at USD 11.29 Billion. GNSS or Global Navigation Satellite System provides positioning, navigation and timing services on a global or regional basis. Market growth is primarily driven by constant breakthroughs and advancements in technologies such as GPS systems. Moreover, increasing investment by governments and private institutions in developing advanced satellite-based services is estimated to further drive the market growth. According to the United Nations Office for Outer Space Affairs (UNOOSA), the International Navigation Systems Commission (ICG) is working to establish interoperability between global systems. It allows GNSS users to receive signals from multiple satellites for navigation and positioning. Moreover, rising security concerns related to civil aviation may also boost the market growth.

GNSS augmentation systems use a combination of ground-based and space-based infrastructure to improve the accuracy, integrity, availability, and continuity of GNSS signals. They may employ techniques such as differential correction, precise point positioning, and real-time kinematic (RTK) positioning to reduce errors and improve positioning accuracy to centimeter-level or even millimeter-level. The market includes various components, such as ground-based reference stations, communication links, processing centers, and user receivers, as well as related software and services.

It is a method of improving navigation system characteristics such as accuracy, reliability, and availability by integrating extended external information from the Global Navigation Satellite System (GNSS) into the calculation process. There are many such systems, and they are commonly named or described based on how the GNSS sensors receive external information. Some systems transmit additional information about the cause of the error (clock drift, ephemeris, ionospheric delay, and others), others provide a direct measurement of how strong the signal has failed in the past, and a third Groups provide additional vehicle information that is integrated into the calculation. Satellite-based augmentation systems (SBAS) use supplemental satellite broadcast messages to support long-range or regional augmentation. Using the measurements from the ground station, a correction message is created and sent to one or more satellites for transmission to the end user as a difference signal. SBAS is sometimes synonymous with WADGPS (Wide-Area Differential GPS).

In addition to this, cloud-based digital services have grown worldwide over the years. For instance, cloud-based services are expected to grow by 30% in 2023 and are estimated to grow even more during the forecast period. Hence, it is also estimated to boost the global satellite-based GNSS augmentation system market growth significantly during the forecast period.
