Mechanisms of Tracer Localizationystem (GPS), the space segment of COMPASS consists of Geostationary Earth Orbit (GEO) satellites, Inclined Geosynchronous Satellite Orbit (IGSO) satellites and Medium Earth Orbit (MEO) satellites, and navigation information is provided by monitoring stations limited in regional area. Besides, attitu

Miscellaneous radiotracer applications,ugmentation System (WAAS) broadcasts a set of ionospheric grids data for authorized single frequency GPS users every 300 s. WAAS uses inverse distance weighting (IDW) algorithm to calculate the vertical total electron content (VTEC) at those ionosphere grid points (IGP). IDW algorithm has good corre

https://doi.org/10.1007/978-94-009-4073-4t. Through the method, the advantage of stable tracking by radio measurements and the advantage of short-range measurement by onboard camera are expect to be fully integrated. The basic idea of the method is as following. First, combined with orbit constraints of a lunar high resolution imaging sate

Biological effects of radiation,biguity resolution (AR) by BeiDou or BeiDou/GPS are analyzed, which are also compared with those by GPS alone. The results show that the BeiDou-only dual-frequency RTK is already feasible, whose single-epoch AR performance and positioning accuracy are compared to those of GPS alone. Furthermore, the
