METHOD FOR ACQUIRING GNSS SIGNALS FOR SATELLITE AND RECEIVER ADAPTED FOR IMPLEMENTING SAID METHOD

摘要

The method involves searching different global navigation satellite system (GNSS) signals from satellites (12). The search is carried-out by cells in a search space, where each cell is attached with a range of code delays and a range of Doppler shifts of the GNSS satellites. The searching process is limited in a first process phase. The cells of the search space are attached with the GNSS satellite and the associated range of Doppler shifts with a high statistical probability of co-occurrence based on an orbital plane of a satellite user positioning system. Independent claims are also included for the following: (1) a global navigation satellite system (GNSS) receiver (2) a computer program comprising a set of instructions a method for acquiring GNSS signals for a satellite.
