NASA 1996 SBIR Phase I


PROPOSAL NUMBER : 96-1 06.01-1100

PROJECT TITLE : Hyperspectral Interferometric Data Compression Module (HI-DCM)

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

During a capability exchange briefing at NASA-ARC, SPEC representatives were surprised to learn that programs like the Environmental Research Aircraft and Sensor Technology (ERAST) and Digital Array Scanning Interferometer (HP-DASI) record large amounts of hyperspectral interferometric data without data compression.

This proposal is to apply state-of-the-art compression techniques to NASA data, present the findings, and define requirements with an objective to design and develop a multipurpose compression module to interface with NASA's family of imaging sensors and platforms, i.e. the various RPV's and the NASA NASA-ARC High Altitude Airborne Science Program.

The real-time compression module will provide frame capture, user selectable lossless or lossy data compression, forward error correction, and modulation for 512X512, 10 bit/pixel using existing Interferometric imagery at 10 frames/s, and will be capable of telemetry of 1024x1024, 16 bit/pixel interferometric images at 20 frames/s. The Phase I study will investigate the use of compression; develop optimal forms of both lossless and lossy compression; determine interface requirements to NASA's family of imaging sensors and telemetry transmitters; definition of decompression software; and coordination with NASA-GSFC on the expansion of algorithm work to this application. Phase II will design and fabricate a prototype compression module capable of supporting flight-tests.

POTENTIAL COMMERCIAL APPLICATIONS
As noted above SPEC plans to apply state-of-the-art compression techniques and develop a Hyperspectral Interferometric Data Compression Module for interface to existing NASA sensors and on-board recorders or telemetry transmitters. The commercial application will depend on the requirements definition and the commercial prospects for the existing NASA sensors and transmitters. As part of Phase I SPEC will assess benefits of the to be defined module and how it may interface with SPEC's existing shock hardened data recorder and telemetry transmitters. Most data compression today is performed in software. The new module will be a hardware solution which may open the door to all kinds of commercial data storage devices.
