Definitions for "Pseudolite"
pseudo-satellite, a ground-based transmitter that mimics a GPS satellite. Intended to improve geometric solutions in a local area. The data portion of the signal may also contain differential corrections that can be used by receivers to correct for GPS errors.
A ground-based differential GPS receiver which transmits a signal like that of an actual GPS satellite, and can be used for ranging.
A ground-based differential GPS receiver that simulates the signal of a GPS satellite and can be used for ranging. The data portion of the signal may also contain differential corrections that can be used by receivers to correct for GPS errors.
