The BeiDou Satellite Navigation System (BDS) has been developing since 1999. Currently, more than 35 BDS satellites are in orbit, including Geostationary Orbit satellites (GEO), Inclined Geosynchronous Orbit satellites (IGSO), and Medium Earth Orbit satellites (MEO). BDS can provide global and regional positioning, navigation, and timing (PNT). In this section, we used an IGS multi-GNSS station MAYG to estimate sea level changes. This station is near the Indian Ocean’s Mayotte. The MAYG station is equipped with a TRIMBLE NETR9 geodetic receiver and a TRM59800.00 antenna. (Latitude: −12.78°, Longitude: 45.26°, Height: −16.35 m). As MAYG is a multi-system GNSS experimental station, it can not only receive GPS and GLONASS signals but also receive tri-frequency BDS signals (L2, L6, L7). We used five available BDS satellites (PRN6-10) to estimate the sea level changes and its local tides from January 2015 to June 2015. In suit sea level data collected by radar sensors at a sampling rate of 1 min were provided by the Intergovernmental Oceanographic Commission (IOC).

摘要

The BeiDou Satellite Navigation System (BDS) has been developing since 1999. Currently, more than 35 BDS satellites are in orbit, including Geostationary Orbit satellites (GEO), Inclined Geosynchronous Orbit satellites (IGSO), and Medium Earth Orbit satellites (MEO). BDS can provide global and regional positioning, navigation, and timing (PNT). In this section, we used an IGS multi-GNSS station MAYG to estimate sea level changes. This station is near the Indian Ocean’s Mayotte. The MAYG station is equipped with a TRIMBLE NETR9 geodetic receiver and a TRM59800.00 antenna. (Latitude: −12.78°, Longitude: 45.26°, Height: −16.35 m). As MAYG is a multi-system GNSS experimental station, it can not only receive GPS and GLONASS signals but also receive tri-frequency BDS signals (L2, L6, L7). We used five available BDS satellites (PRN6-10) to estimate the sea level changes and its local tides from January 2015 to June 2015. In suit sea level data collected by radar sensors at a sampling rate of 1 min were provided by the Intergovernmental Oceanographic Commission (IOC).
