GPS Sensor Meets Or Exceeds ADS-B Out Positioning Source Requirements
CMC Electronics has completed development and testing of a customized version of their CMA-5024 SBAS GPS for B777 aircraft under license with Boeing. This tailored version (P/N 100-601967-121) has been installed on several B777-200 aircraft with major airlines wherein the CMA-5024 fully integrates with the on-board avionics, including AIMS.
The CMA-5024 is an approved TSO-145/146 SBAS GPS sensor that meets or exceeds ADS-B Out positioning source requirements and easily pairs with any RTCA/DO-260B transponder. The CMA-5024 offers B777 aircraft a cost-effective ADS-B Out solution and a high performance SBAS navigation sensor for all phases of flight. This high performance navigation solution can enable RNP0.3 or better.
CMC Electronics president Robin St-Arnaud had this to say about this licensing arrangement with the world’s largest commercial aircraft manufacturer: “We are delighted with the Boeing licensing arrangement and we look forward to serving the industry. Our CMA-5024’s quality, versatility and reputation are well known; it is a proven solution that can be relied on.”
CMC has a certified service bulletin to replace the existing GPSSU (GR-550 or HG2021GP01) with the CMA-5024 and is currently developing an STC for MMR equipped B777 aircraft. As bolt-on solution, installation involves minimal aircraft modifications with a turn-around time in less than a day.
The CMA-5024 also provides a built-in, standalone LP/LPV capability that can enable B777 aircraft to take advantage of SBAS LPV approach capability with minimal effort. An LPV approach is the highest precision SBAS instrument approach available that does not require specialized crew training as it is an ILS look-alike. With this LPV capability, air carriers can expand their operations to airports that are not equipped with ILS.
The CMA-5024 meets the requirements for an instrument flight rules, civil certified global navigation satellite system (GNSS). The European Geostationary Navigation Overlay Service (EGNOS), a component of SBAS, augments GPS to provide an extremely accurate navigation solution that will support all flight operations from en route to localizer performance with vertical guidance (LPV) CAT-l equivalent approach. The CMA-5024 is compliant with and completely supports all SBAS implementations (WAAS, EGNOS, GAGAN, …), from departure, en-route navigation, and all SBAS LPV precision approaches.
