Abstract
A system and method for providing navigation through an underground space. The method includes receiving ephemeris data of a plurality of satellites in orbit at a location of the underground space, determining a schedule of the plurality of satellites in orbit, obtaining location of a plurality of pseudolites within the underground space, and determining satellite parameters to configure each of the plurality of pseudolites. Satellite parameters are determined based on the obtained location of each pseudolites and the determined satellite schedule. Also, the satellite parameters include at least a signal modulation parameter and a broadcast data parameter. The method also includes configuring each of the plurality of pseudolites with the respective satellite parameters, and controlling the plurality of pseudolites to broadcast satellite signals based on the determined satellite parameters. The broadcasted satellite signals simulate locations of the plurality of satellites in orbit.
