Metstar - Ground-Based Navigation Satellite Integrated Sounding System for Water Vapor and Ionosphere

Tracking signal: BDS, GPS, GLONASS and Galileo navigation satellite system signals, with BDS3 PPP-B2b   data receiving and processing functions. Observation function: Observation data include dual-frequency ranging code, dual-frequency carrier phase value and four system satellite broadcasting ephemeris BDS/GPS/GLONASS/Galileo, etc. ZTD and PWV will generate hourly and minute-level products in real time. Detect the satellite   ionospheric TEC?ROTI and ionospheric scintillations to  generate hourly products and minute-level products in real time. The total electron content (), ionospheric perturbation (ROTI) and ionospheric scintillation were detected, and hourly and minute level products were   generated in real time.
