STPSat-1 Completes One Year in Orbit

PHOENIX - March 23, 2008/Radyne Corporation (Nasdaq:RADN). - AeroAstro, a business unit of Radyne, announced today that the company's STPSat-1 spacecraft has successfully passed its one-year anniversary of on-orbit operations. STPSat-1 began its mission after a successful launch on March 8, 2007 aboard an Atlas V rocket from Cape Canaveral, Florida. Following a rapid checkout period that was completed in less than three weeks, two experiment payloads built by the Naval Research Laboratory (NRL) began nominal operations and have provided valuable science data over the one-year period.

STPSat-1 is the first DoD Space Test Program (STP) mission explicitly designed to utilize the Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) developed by the US Air Force. AeroAstro's STPSat-1 satellite is the first commercially developed spacecraft designed and fully qualified for compatibility with the ESPA.

"The STPSat-1 mission has proven the utility of ESPA as a viable secondary launch opportunity," said the Space Development and Test Wing Space Development Group Commander and STP Director Col. Stephen Hargis. "STPSat-1 was placed in its desired orbit and has fulfilled its mission objectives furthering STP's goal of providing opportunities for innovative space technologies to be proven on orbit. We anticipate more ESPA launches in the future to take advantage of excess EELV launch capacity; STPSat-1 has served as a useful pathfinder for that option. "

STPSat-1's primary payload, the Spatial Heterodyne Imager for Mesospheric Radicals (SHIMMER) is a high-resolution ultraviolet spectrometer pioneering the optical technique of Spatial Heterodyne Spectroscopy (SHS) for satellite applications. With this mission, SHIMMER has successfully demonstrated satellite borne SHS by providing unprecedented hydroxyl (OH) measurements in the middle atmosphere and detecting mesospheric clouds. The SHIMMER instrument performed flawlessly and met its mission objectives.

The secondary payload is the Computerized Ionospheric Tomography Receiver in Space (CITRIS), a four frequency receiver connected to an antenna located on the top face of the STPSat-1 satellite. By taking measurements of the signals emitted from other satellite beacons and ground signal sources, CITRIS provides measurements of satellite-to-satellite and space-to-ground Total Electron Count (TEC) and signal fluctuations. Occultation of the earth's ionosphere can be used to derive electron density profiles from the TEC measurements.

"We are very pleased to have fulfilled the on-orbit requirement for the STPSat-1 mission with excellent results for both the hosted payloads," said Pat Remias, Executive VP and General Manager of AeroAstro's Space business group. "The satellite continues to operate well, and the experience we've gained is directly benefiting the STP's Standard Interface Vehicle (SIV) program, for which we are the bus supplier to Ball Aerospace, and our work in operationally responsive space."
