The invention discloses a satellite navigation system baseband signal processing system and a method, which is suitable for the fusing of signal processing of multiple satellite navigation systems by a receiver. The system comprises medium frequency signal interface modules which are connected with radio frequency front ends of multiple satellite navigation systems and are used for receiving medium frequency signals in different types for conversation to obtain medium frequency signal in the same type; an allocation module for storing the medium frequency signal in the same type according to a preset allocation rule; a memory for storing the medium frequency signal in the same type; a distribution module for distributing the medium frequency signal in the same type according to a preset distribution rule; and a channel gathering module which comprises a plurality of channels and is used for tracing and processing the medium frequency signal in the same type distributed by the distribution module. The processing system and method in the invention can perform fusion processing for various satellite navigation systems, has small circuit scale, meets the requirement of compatibility for the existing satellite navigation systems, and saves cost.
Description
technical field [0001] The invention relates to a satellite navigation system receiver, in particular to a baseband signal processing system and method in the satellite navigation system receiver. Background technique [0002] Global Navigation Satellite System (GNSS) is a general name for a standard satellite navigation system that provides autonomous geospatial positioning around the world. GNSS allows small electronic receiving devices to measure their position (including longitude, latitude and altitude), speed and time by regularly receiving radio wave signals emitted by satellites within the range along the line of sight. [0003] So far, the US Navigation Star (NAVSTAR) Global Positioning System (GPS) is the only GNSS that has been fully implemented. Russia's GLONASS navigation system is currently in the process of being repaired and is expected to be fully operational in 2010. The European Union's Galileo positioning system (Galileopositioning system) is still in t...
