International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The desire to acquire large quantities of high speed vibration and acoustic data during
aircraft testing is usually satisfied through on-board high speed recording methods.
However there is often a need to have some of this data instantly available at the
ground station for flight safety and other purposes.
A Data Processor (DP) has been developed allowing an airborne data acquisition
system to acquire large amounts of wideband analog data, process the data in real-time,
and develop reduced bandwidth information from high bandwidth channels. The
reduced data can be inserted into a Pulse Code Modulation (PCM) stream and
telemetered via a Radio Frequency (RF) link with a potential for a 2000:1 reduction in
bandwidth.
This on-board processing capability also lends itself to additional tasks such as the
generation of a reduced bandwidth marker channel which can flag critical time periods
of data activity. This flagging technique can be used to facilitate ground station
analysis of specific segments of data, resulting in significant cost and time savings.
