A10: Global Navigation Systems (Overview of the timing techniques in the various satellite systems)

Thursday, August 21  14:40-15:20,  Room #18

Satellite navigation provide autonomous geo-spatial positioning with global coverage. Receivers determine location (longitude, latitude, and altitude) to within a few metres using time signals transmitted along a line-of-sight by radio from satellites. Some systems are localized to a region of the world at present, while other offer world-wide coverage. This session focuses on the additional systems that include NAVSTAR (GPS) and GLONASS as globalsystems. The Chinese regional Beidou navigation system was presented in the tutorial. The European Union's Galileo positioning system is a GNSS in, scheduled to be fully operational by 2020. India, France, and Japan are also in the process of developing regional navigation systems
