Exelis Tests Air Force GPS III Transmitter Assemblies; Mark Pisani Comments

Exelis-logo, ExecutiveMosaicExelis has demonstrated six transmitter assemblies that are built to function as payload components for the U.S. Air Force's first set of GPS satellites.

The transmitters were tested in a simulated space environment for random vibration, pyroshock and thermal vacuum to qualify for the GPS III's mission requirements, Exelis said Tuesday.

McLean, Va.-based Exelis built the transmitters to send GPS signals between space and Earth for military, commercial and civilian users.

Mark Pisani, vice president and general manager of positioning, navigation and timing business area for Exelis Geospatial Systems, said the navigation payload transmitters will be replicated for the next space vehicles.

The GPS III team led by the Air Force's GPS directorate is developing the navigation payload in Clifton, N.J.

NASA Picks Luna’s RIO Laser for Navigation Doppler LiDAR

NASA has selected a Luna Innovations-built semiconductor laser for use in its Navigation Doppler LiDAR system. “To precisely measure the vehicle speed, direction, and distance, our NDL system uses both Doppler shift and laser beam travel time, which requires a highly stable single-frequency laser source,” said Farzin Amzajerdian, NDL principal investigator from NASA Langley Research Center. “The RIO laser from Luna Innovations has met NASA’s requirements for high reliability, low noise, and ultra-narrow linewidth.”
