Does my location matter in relation to your reference stations?

For TerraStar-M, the accuracy will depend on the distance between the user location at the nearest reference station(s). All other TerraStar services are based on precise point positioning (PPP) in which corrections are applicable anywhere that the GNSS satellites are in view.  These corrections are independent of any specific reference station.  Users may experience variations in the accuracy of their solution, but this is typically due to local conditions, including the atmospheric activity in the region, rather than any variation in the correction service.
To receive corrections over geostationary satellites a user must have visibility of these signals, which is typically possible to a latitude of around 80 degree in unobstructed areas. TerraStar signals can only be used on land (see Geogating for further details).
