Esterline’s CMA-5024 GPS/SBAS landing system sensor unit (Esterline)
Esterline Avionics Systems and PMV Engineering have received EASA approval for the upgrade of the older generation GPSSU by CMC’s CMA-5024 GPS/SBAS Landing System Sensor Unit (GLSSU) on the Airbus A320 family of aircraft.
The CMA-5024 is an approved DO-260B ADS-B positioning source that may be paired with any DO-260B transponder. It can be coupled with ADS-B Out STCs from PMV Engineering or others to meet the ADS-B Out requirements mandated worldwide.
The PMV Engineering solution offers the unique advantage of reduced install and downtime for the A320 family of aircraft since it involves a form, fit and function replacement of the existing GPS unit without the need to perform any structural modifications. The CMA-5024 also allows the entire aircraft to take advantage of SBAS navigation throughout all phases of flight. Localizer performance with vertical guidance (LPV) approach capability may be added with additional certification effort.
Similar solutions are ongoing for Boeing 747-400 and B777-200 aircraft.
Esterline is exhibiting at the Farnborough Airshow at Hall 1, Booth 1180.
