Abstract:	The usefulness of GPS technologies for various remote sensing applications is well known. Both ground-based and space-based receivers are used for a variety of applications including monitoring the Earth’s ionosphere, the troposphere, ocean characteristics, accurate geoid characterization, and so on. Use of satellite-borne receivers in conjunction with ground-based receivers provides superior reconstructions of the ionosphere and the troposphere. For ionospheric reconstruction, additional information is also available from low frequency beacon satellites. Plans for several such satellites are currently being developed. We present the results of simulation where these integrated observations are used for reconstruction of the 3-D ionosphere. Details of receiver systems suitable for satellite-borne monitoring, GPS and low frequency beacons are presented. These satellite-borne receivers are currently being fabricated at CRS under the sponsorship of ONR. The flexible architecture allows these receivers to be used for a variety of other missions.
