Method for acquiring GNSS signals for a satellite and receiver suitable 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.
