Navigation Laboratories makes two basic types of GPS Constellation Simulator products: LabPro -- high end and targeted for R&D activities and LabMate -- entry level and more applicable to manufacturing activities. A Constellation Simulator generates an RF signal that emulates those received from the entire 24-satellite GPS constellation. This emulation includes modeling of the GPS satellite orbits and perturbations, telemetry data up-link, earth horizon and masking effects, propagation through the atmosphere, effects of special and general relativity, etc. A Constellation Simulator also models motion and dynamics of the simulated host vehicle that receives the GPS signal. The Navigation Laboratories' simulator includes effects due to vehicle masking, auxiliary support sensors such as inertial measurement units, antenna models, multi-path, etc.

The Navigation Laboratories GPS products will be sold in a stand-alone fashion and as an integrated part of the recently acquired Racal Instruments Wireless Solution (RIWS) test systems.
