CSSI’s Enhanced2 GPS Monitoring Unit (E2GMU)
The Enhanced2 GPS Monitoring Unit (E2GMU) is utilized to support the RVSM monitoring program and is manufactured by CSSI for commercial sale.
​
CSSI jointly designed and developed the E2GMU with the FAA’s North American Approvals Registry and Monitoring Organization (NAARMO) as the next generation monitoring equipment. The FAA granted CSSI exclusive approval to produce the E2GMU for commercial sale for the continued support to the RVSM monitoring program. The E2GMU utilizes the latest in tablet computing devices, an open-source software operating system foundation, and the latest GPS receiver specifications. The E2GMU system also features an integrated Altitude Recording Device (ARD) to capture aircraft pressure altitude with Mode C. The E2GMU is classified as a portable electronic device and is powered completely independently from aircraft systems with contained rechargeable batteries. The E2GMU features a custom designed tablet software interface controller, which allows the user to transfer all recorded data from the tablet by using the device with a Wi-Fi or Bluetooth connection after the testing has completed. These components are contained in a custom case which meets airline standards for carry-on luggage.
The E2GMU uses an onboard GPS Receiver manufactured by JAVAD, Inc. and receives GPS radio signals via two (2) GPS antennas placed on aft and starboard interior aircraft windows secured with suction cups. The E2GMU GPS receiver is calibrated for positional accuracy during the installation inside the aircraft while the aircraft is stationary on the ramp. The Altitude Recording Device (ARD) is calibrated by the operator by entering the four digit Transponder Code of the aircraft to be monitored for RVSM performance. Once the RVSM Monitoring flight is completed the GPS data is submitted to CSSI and is processed using a Differential GPS Correction software method to correct the errors in the GPS data. For flights completed in the Africa region (AFI Region) and for aircraft registered in North America (NAARMO) CSSI is authorized to calculate the Altimetry System Error (ASE) and submits those results to the respective ICAO Regional Monitoring Agency (RMA) for final RVSM approval for the aircraft.
