16:40 GMT, February 26, 2010 FORT LAUDERDALE, Fla. | Rockwell Collins has successfully conducted UHF SATCOM and HF waveform Functional Qualification Testing (FQT) on the Joint Tactical Radio System (JTRS) vehicular Ground Mobile Radios (GMR). This testing is conducted to ensure that the Software Communications Architecture compliant waveforms met all allocated JTRS requirements.

FQT reasonably simulates the production environment. Successfully conducting FQT verifies that the UHF SATCOM and HF waveforms will provide expected operational waveform functionality before GMR systems are fielded. The waveforms can then be used to support the Production Qualification Testing phase of the GMR program.

"We are very excited about bringing this important communications capability to the warfighter," said Bruce King, vice president and general manager of Surface Solutions for Rockwell Collins. "JTRS GMR will enable warfighters to do what they've never been able to do with a single communication device - communicate with each other seamlessly in an ad hoc network using next generation waveforms, such as WNW and SRW, while also utilizing legacy HF and UHF SATCOM capabilities."

Like all JTRS Operational Requirement Document waveforms in the 2 MHz to 2 GHz frequency range, the UHF SATCOM and HF waveforms can run in any of the GMR system's four reprogrammable Universal Transceivers.

Rockwell Collins is a member of the Boeing-led GMR team whose vehicular JTRS radio design is based on the Rockwell Collins Modular Communications Platform - a unique Software Defined Radio packaging concept which partitions hardware modules according to function at the lowest operational level. This innovative approach substantially improves mission effectiveness and simplifies testing, repair and upgrades in the field, while the design reduces total life cycle cost for platforms on the battlefield.
