ASIST Product Brief:

Advanced System for Integration and Spacecraft Test (ASIST) provides complete off-the-shelf COTS satellite telemetry and command processing for integration and test (I&T) and operations environments.

ASIST has successfully supported many missions in I&T and/or Flight Operations throughout the aerospace community, including: WMAP, EO-1, FUSE, ST-5, GLAS, IMAGE, TRMM, XTE, CIRS, ATRO-E(XDS), HST, Landsat-7, EOS-Aura, JWST, and X37.

ASIST has logged hundreds of thousands of hours in both I&T and Flight Operations, and because of its superior design and track record, ASIST has recently been selected (over all other competitors) as the STANDARD ground system at NASA Goddard for all Flight Software testing and development. The designAmerica ASIST Engineering Team is the best in the business, and has won many awards at NASA for its superior product support.

The ASIST product suite is a completely integrated, extensible, and easy to interface system, consisting of 3 parts, FEDS, DHDS, and the ASIST W-S:
