Airborne Controller for Long-Time Image Data Recording

ASTREC-4 is a rugged, sealed camera controller that supports up to 4 H-EM high-speed streaming cameras.

The unit is equipped with extensive non-volatile memory capacity for recording high-speed events up to hours. Other sensor or data logger may be connected to the recorder upon request. ASTREC-4 with its cameras can record events during a complete mission in high speed for later play back in slow motion for in-depth quantitative and qualitative analysis. Recordings providing a full coverage especially in rotary-wing aircraft provide data for analysis that has not been possible before. Once the system is back the storage bay can be removed for analysis in the lab, which grants fast-turnaround time of the test vehicle.

Typical users are manufacturers of aircraft, and test ranges for rotary and fixed-wing aircraft. However, the ASTREC-4 streaming system fits application for land-based tests as well. The four cameras generate a stunning data rate of up to 3,000 frames a second per camera directly into the non-volatile storage of the controller. By a HD-SDI output a live view is available to see the image data stream while recording in remote places or have it connected to telemetry link for ground station view. For synchronisation of the camera purposes the built in IRIG-B 122 receiver generates time stamps of every frame.

The comprehensive Imaging Studio V4 software is ready for later data analysis, playing back and converting sequences into common movie formats. ASTREC-4 is tested and certified according to EMI 461 / MIL-810 and DO-160.
