Sentinel - Crash Survivable Memory Unit is an optional unit design for all our Airborne Data Recorders, if you need a crash protected module (CPM) for your applications like flight testing, to be sure to recover data in case of a serious accident. This CPM has been design to meet all the performance and survivability requirements of EURO CAE ED-155 or ED- 112 normalization.
To take an example you can have a mission recorder in the cockpit with removable cartridge and have a sentinel unit in the tail of the plane connected to the mission recorder who recorded exactly the same things or add on parameters.
Sentinel CSMU is available in two types of Version CSMU-ED155 light version and CSMU-ED112 more rugged version. An optional underwater acoustic beacon is available to facilitate the location of the recorder
You can configure the recorder to meet your specific requirements for your air vehicle. The all in one solution package that weighs ~5Kg (11lbs) with Nano airborne recorder.
Sentinel recorder can be designed on your specific requirement, you no longer have to compromise on what you want or spend your limited engineering resources to modify an existing system.
