The scintillation and tomography receiver in space (CITRIS) instrument will orbit the earth near 560 km altitude to detect signals from the array of 56 DORIS UHF/S-Band radio beacons located at sites around the world by the French CNES. CITRIS will record ionospheric total electron content (TEC) and radio scintillations with a unique ground-to-space geometry. New algorithms have been developed to study the ionosphere using data obtained with the UHF and S-Band radio transmissions from the DORIS beacons. Numerical models are used to predict the DORIS signals measured by CITRIS. The data from the space-based CITRIS receiver will help update and validate theories on the generation and effect of ionospheric irregularities known to influence radio systems. By using simultaneous beacon transmissions from DORIS on the ground and from low-earth-orbit beacons in space, the concept of reciprocity in a non-bilateral propagation medium like the ionosphere will be tested.
