Method for satellite-based determination of position of satellite receiver for mobile device, involves applying distance estimation for position determination on detecting intervisibility between satellite receiver and satellite

摘要

The method involves detecting whether the satellite receiver has intervisibility with the satellite, and applying distance estimation generated based on a delay locked loop algorithm for position determination when the intervisibility between the satellite receiver and the satellite is detected. The distance estimation generated based on an estimation algorithm, particularly particle receiver algorithm for position determination is applied when the intervisibility between the satellite receiver and the satellite does not exist. The detection of intervisibility with satellites is carried out by measuring the strength of the satellite signal, and the intervisibilty is recorded when the strength of the satellite signal exceeds a predetermined threshold.
