Advanced Techniques for Lossless Compression of Target Vehicle Telemetry
We propose to create a unique on-board software platform that will compress without loss a wide variety of telemetry data, including health and status information of vehicle body components, kinematic information, and visible and IR imagery. Different sub-systems treat encrypted and original data. The encoding software will meet the specifications of low complexity, fast computation, and low latency. It will be easily portable to other processors and reconfigurable in hardware. The uniqueness stems from the use of a single compression algorithm, SPIHT (Set Partitioning in Hierarchical Trees), to encode all the numerical data, regardless of dimension. The compression techniques therefore inherit the properties of spatial and rate scalability inherent to SPIHT. No other compression system has the flexibility of the proposed system and meets the specifications of low complexity, fast computation, and low latency.
