Product Overview and Main Content
Global Navigation Satellite System(GNSS)
- GNSS is a radio navigation system that can determine the user's exact location using timing information and navigation data sent from navigation satellites in orbit of approximately 20,000 km.
- Major GNSSs in operation worldwide include GPS of the United States, Galileo of Europe, GLONASS of Russia, and BeiDou of China.
- Recently, combined GNSS receivers that can receive GPS and Galileo signals are being used in the precision orbit determination of LEO and GEO satellites.
- GNSS is being used in a variety of areas, including civilian, aerospace, and defense, where precise location information is required, and is a key technology that will lead to the development and innovation of future societies.
Product Highlights
- Using the navigation information of the combined GNSS receiver for satellites, it is possible to determine the orbit of the satellite more quickly and accurately, thereby reducing the cost of satellite tracking and extending the life of the satellit
-
Combined GNSS receiver for LEO satellites (heritage securing phase)
- Development of a qualification model for the combined GNSS receiver for LEO satellites.
- Manufacture of a flight model for the combined GNSS receiver for next-generation small satellite No.2.
- In order to secure space heritage, it is being operated on the next- generation small satellite No. 2 launched in May 2023.
-
Combined GNSS receiver for GEO satellites (qualification model development phase)
- Currently developing a qualification model for the combined GNSS receiver for GEO satellites.
- Currently developing navigation solutions in environments with limited visible GNSS satellites and their weak signals reception.
- Currently developing a TRL 7-level product that meets the requirements of NASA's product assurance regulations.

Business Results
Market Outlook
- Combined GNSS receivers for satellites are high value-added products and have high technical barriers to entry, which require a long period of time to develop commercial products, and can have global competitiveness if space heritage is secured.
- In the New Space era, the domestic and international space markets in the commercial and defense areas are expanding on a large scale, resulting in significant economic benefits.
Commercialization Plans
-
- The GPS/Galileo integrated receiver for low-earth orbit satellites which is currently under space heritage review can be used for satellites for scientific missions, next-generation small and medium satellites, low-orbit broadcast satellites, low-orbit earth observation satellites, etc.
- The GNSS integrated receiver for geostationary orbit satellites, which is expected to finish development in 2024, can be used for next-generation geostationary orbit communications satellites, next-generation geostationary orbit marine/meteorological satellites, etc.
