Interferometric orbit determination for geostationary satellites [PDF]
The final publication is available at link.springer.com via http://dx.doi.org/10.1007/s11432-016-9052-y Future GeoSAR missions are expected to provide higher resolution radar images featuring shorter revisit times by locating a radar payload on-board of a geostationary satellite. One of the main challenges in GeoSAR processing is accurately determining

Modeling and Analysis of Battery Thermal Control in a Geostationary Satellite
Battery technology has been used for geostationary satellites since the first satellite sputnik-1 was launched in 1957. The majority of larger geostationary satellite’s lives range from 7 to 15 years. During the lifetime of satellites, the batteries used

Pioneering evaluation of GaN transistors in geostationary satellites [PDF]
AbstractIn this paper, we present the results of a 6-year experiment in space that studied the effects of radiation in Gallium Nitride (GaN) electronics in geostationary orbit. Four GaN transistors in a Colpitts oscillator configuration were flown in the Component Technology Test-Bed aboard the Alphasat telecommunication satellite. A heuristic analysis
