8. SatNav Systems
10. GPS Satellite Constellation
11. Satellite Navigation Systems A system of satellites that provide autonomous geo-spatial positioning with global/regional coverage that allows small electronic receivers to determine their location (longitude, latitude, and altitude) to high precision (within a few metres) using time signals transmitted along a line of sight by radio from satellites. – Global: GPS, GLONASS, Galileo (2020) – Regional: BeiDou, NAVIC, QZSS
12. Environment and Accuracy • Line-of-sight to horizon is required for improved accuracy • Weather, time of day, precipitation affect radio signal, and may cause it to vary. • Radio chip is also a significant factor
15. Issues
