The proposed effort is to design a space-qualified dual-frequency GPS/GLONASS receiver with enhanced capabilities for atmospheric remote sounding. While such soundings have been performed using GPS-only receivers, a space-based GPS/GLONASS receiver would be superior in terms of coverage and integrity cross-checking, as well as the ability to process the unencrypted GLONASS L2 signal. This design will be based on the company's existing dual-frequency GPS/GLONASS receivers. The company can therefore concentrate its SBIR-sponsored efforts on porting its proven GPS/GLONASS technology to the space environment. Commercial applications:The basic receiver hardware and software will also be applicable to spacecraft navigation and attitude measurement.
