TerraStar is a global, high accuracy positioning service which is robust and effective in all locations--including areas of high ionospheric disturbance--and is ideal in precision applications where communications infrastructure is either unreliable or not available.
TerraStar-C is a correction service currently available for Ag Leader GPS 6500 receivers that offers improved accuracy and faster convergence, with the ability to quickly regain full accuracy when GNSS signal is temporarily lost. TerraStar-C offers worldwide centimeter level accuracy, delivered via satellite. Seven independent L-band satellites in constellation ensure a minimum of dual beam coverage anywhere in the world. 1.5" pass to pass accuracy.
