Description

technical field [0001] The invention belongs to the technical field of global navigation satellite systems, and in particular relates to a satellite signal transponder that provides accurate transponder positions in real time. Background technique [0002] The Global Navigation Satellite System (GNSS) is a space-based radio navigation and positioning system that can provide users in the earth's surface or near-Earth space with precise three-dimensional coordinate positioning, speed measurement, and timing services. The global satellite navigation system (GNSS) is mainly composed of GNSS satellites distributed in the sky and GNSS receivers on the ground. GNSS satellites continuously transmit navigation messages (GNSS signals), and GNSS receivers receive navigation messages (GNSS signals) to calculate and obtain time , location coordinates and other information. The GPS satellite navigation system (Global Positioning System) of the United States, the GLONASS satellite navigat...

Problems solved by technology

[0007] Existing scheme one can provide accurate forwarding position coordinates, but the forwarding position can only be fixed on the geodetic standard point, when the receiving antenna of the satellite signal transponder device moves, it cannot provide accurate forwarding position coordinates in real time; the existing scheme two The satellite signal forwarding device can provide real-time forwarding position coordinates when its receiving antenna moves, but because the GNSS receiver in the satellite signal repeating device obtains the forwarding position coordinates by single-point positioning, the accuracy of the forwarding position coordinates cannot be guaranteed. Provides forwarded location coordinates with meter-level accuracy
