摘要:Pseudolite is a contraction of the term pseudo-satellite, used to refer to something that is not a satellite which performs a function commonly in the domain of satellites. A pseudolite is installed on the ground, which sends the same waves as those from a GPS satellite to enable positioning in locations where it is difficult to receive the waves from GPS satellite, such as between tall buildings, underground, and indoors. The pseudo-range measurement accuracy of pseudolite depends on the performance of clock synchronization between pseudolite and GPS satellites. This paper proposes clock synchronization algorithm for pseudolite. It is a revision and improvement of the time comparison technique based on GPS code transfer in order to determine the UTC.
