Abstract
Systems, methods, devices and subassemblies for creating and delivering a GNSS augmentation service include one or more reference stations for receiving signals transmitted by navigation beacons and an augmentation server coupled to the reference stations. At least one of the reference stations is able to receive at least one of the signals from a low earth orbit satellite. Each of the reference stations determines first navigation observables based on the received signals and transmit information associated with the first navigation observables to the augmentation server. The augmentation server is configured to determine and distribute augmentation information to a receiver. The augmentation information is based on the received information associated with the first navigation observables, locations of the reference stations, and computational models. The distributed augmentation information is usable by the receiver to determine a high-precision position, velocity, and time solution for the receiver based on second navigation observables associated with the receiver.
