09/23/2010 - NASA Chooses Spirent Federal for GPS L1/L5 and GPS/Inertial Testing

Spirent Solves Critical Test Needs for Space Applications

Yorba Linda, California - (September 23, 2010) - Spirent Federal announced today that NASA has chosen Spirent simulators for their Range Technologies Development Lab at Kennedy Space Center. NASA selected a GPS L1/L5 and inertial test system, and a portable simulator for in-the-field GPS L1 testing.

A key element of spacecraft development and verification is testing GPS and satellite-based augmentation system (SBAS) receivers. Spirent simulators offer comprehensive test capabilities, such as modeling of spacecraft orientation, antennas, and the ionosphere, as well as multiple RF output configurations for platform attitude testing.

The modernized GPS L5 signal will be particularly useful in reducing ionospheric errors and enabling precise landings of air and spacecraft, even in high multipath environments. "While full L5 coverage won't be available until GPS modernization is complete, we've offered L5 testing capability since 2003, helping development teams prepare today for GPS modernization," stated Jeff Martin, director of sales for Spirent Federal. "We are pleased to be able to provide NASA the advanced testing technology needed to get the job done."
