The space-based multi-band CITRIS receiver records total electron content (TEC) and radio scintillations from satellite beacons in low-earth-orbit plus the global network of ground DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite) beacons. The measurement of ionospheric TEC provides inputs for space-weather models over remote regions of the Earth and allows for tracking of ionospheric disturbances. The CITRIS satellite-to-satellite TEC measurement uses the differential phase technique. The CITRIS receiver is currently in orbit at 560 km altitude on the STPSat1 satellite at 35 degrees inclination. CITRIS records TEC and radio scintillations from beacon transmitters on the Taiwan FORMOSAT3 at 150/400/1067 MHz, DMSP/F15, RADCAL, GFO and COSMOS at 150/400 MHz plus other satellites in low earth orbit. The ground-based DORIS geodesy beacons operate at 401/2036 MHz. The innovative satellite-to-satellite measurements provide new capacities. Satellite-to-satellite measurements have three stages: 1) ionospheric occultation at large separations, 2) minimum distance TEC sampling when the beacon passes directly over the receiver and 3) a second occultation. Absolute TEC is obtained by extrapolation to zero satellite separations. In such cases, it is possible to retrieve absolute TEC with less than 0.1 TECU errors. Initial tests using CITRIS data in data-assimilation space weather models shows the value of the technique. We will report on the first year of measurements from the CITRIS receiver. Future space missions would benefit from flying CITRIS receivers to give global radio measurements of the ionosphere at 150, 400, 1067, and 2036 MHz. *Supported by ONR
