CALGARY, Alberta. U.S. Federal Aviation Administration (FAA) officials tasked NoVatel to design, produce, and deliver 40 next-generation Ground Uplink Station (GUS) Signal Generators to support the FAA?s Wide Area Augmentation System (WAAS) navigation service.

Under contract, NovAtel will help modernize the WAAS network by upgrading and extending support for the network’s GUS infrastructure. The next-generation of GUS Signal Generators, which are designed specifically for SBAS ground uplink systems, will include independent L1 and L5 signal paths to precisely control the frequency and phase of L1 and L5 code and carrier for dual-frequency SBAS. A GUS receiver system based on the WAAS G-III receiver platform will also be released along with the Signal Generator to complete the modernized GUS control loop.

The contract also includes ongoing engineering support services of the company's Satellite Based Augmentation System (SBAS) products deployed by the FAA, including the WAAS G-III reference receiver platform.

The WAAS network is a safety-critical navigation aid that allows aircraft to use the U.S. Global Positioning System (GPS) for all phases of flight. Every time an aircraft takes off or lands within the WAAS coverage area, NovAtel technology is generating and processing data that allows aviators to make precision approaches to any airport.
