Abstract
A Geostationary Earth Orbit (GEO) satellite belonging to a constellation of satellites of a BeiDou navigation system is acquired at a GNSS receiver. Conducting the acquisition includes finding the edge of a data bit in a signal carrying a data stream of a given satellite in order to start a locked tracking phase and demodulating the data stream of the GEO satellite. Detecting the edge of the data bit includes performing, at the GNSS receiver, a coherent power accumulation over a constant data cycle, starting from two respective possible initial positions in the sequence of data. Detecting the edge of the data bit also includes computing a tracking ratio parameter as the ratio of the two coherent power accumulations multiplied by a constant value.
