A navigation bit boundary determination apparatus and a method thereof

摘要

A navigation bit boundary determination apparatus and a method thereof is disclosed. The navigation bit boundary determination apparatus includes a Beidou satellite signal receiving module, a position receiving and clock calibration module, a calculation module, and a determination module. The Beidou satellite signal receiving module receives a Beidou Geostationary Earth Orbit (GEO) satellite signal, determines and records a local receiving time of the Beidou GEO satellite signal. The position receiving and clock calibration module receives a GPS time signal and a position of the navigation bit boundary determination apparatus. The calculation module calculates a transmitting time for the Beidou GEO satellite signal. The determination module determines a navigation bit boundary of the Beidou GEO satellite signal.
