Abstract:
1. An apparatus for transmitting pseudolite signals for navigation, comprising: an integrated pseudolite including at least four pseudolites each configured to generate and output a pseudolite code; at least four geometrically disposed antennas, each corresponding to one of the pseudolites in the integrated pseudolite and configured to transmit a pseudolite signal outputted by the corresponding pseudolite containing the pseudolite code; and a single synchronization clock unit connected to the integrated pseudolite and configured to provide a synchronization clock to each of the pseudolites in the integrated pseudolite, so as to synchronize the pseudolites to the synchronization clock, wherein each of the pseudolites in the integrated pseudolite simultaneously outputs the pseudolite code including a PRN (pseudorandom noise) identification number, pseudolite position information and antenna calibration information through the one of the antennas; the PRNs are used as the pseudolite signals for navigation and are simultaneously transmitted to the antennas, each PRN to one of the antennas corresponding to one of the pseudolites that generates the PRN, and the pseudolites are integrated into a single platform to be synchronized by a single clock as the synchronization clock.
