The TA-12 is the industry's first standalone P(Y) code Global Positioning System (GPS) sensor to receive TSO certification for both military Precision Positioning Service (PPS) and commercial Standard Positioning Service (SPS) aviation operations.

The announcement was made at the Institute of Navigation GPS '99 Conference.

"For military aircraft, FAA certification for navigation systems is an emerging requirement," said Jeff Tonnemacher, Trimble's director of military and advanced systems. "Trimble is proud to be the first and only supplier of a 12-channel, FAA TSO'd GPS sensor that addresses this market need."

Trimble's TA-12 was designed for military and commercial aviation applications requiring a robust GPS receiver for integration with existing or new Flight Management Systems that require Instrument Flight Rules (IFR)-certified operations.

The TA-12 is a dual frequency, all-in-view, 12-channel GPS receiver that meets key GPS Receiver Applications Module (GRAM) requirements. It corrects for Selective Availability (SA), incorporates Receiver Autonomous Integrity Monitoring (RAIM) and Fault Detection Exclusion (FDE), and protects against spoofing. The TA-12 has interface capabilities to dual FMS, IRS and Air Data installations using ARINC 743 standards. It also provides users with an upgrade path to WAAS and SAASM.
