From: "Patrick Coronado" To: Subject: AQUA GBAD Algorithm ReleaseDate: Thu, 16 May 2002 16:06:06 -0400X-Priority: 3 (Normal)Importance: NormalSender: owner-direct_broadcast_users@listserv.gsfc.nasa.gov Reply-To: "Patrick Coronado" Status: DB Community,The Direct Readout Lab at NASA Goddard is pleased to announce the release of the Ephemeris and Attitude Data Converter (GBAD) software that creates ephemeris and attitude files from data packets in the AQUA spacecraft telemetry downlink. The program reads a CCSDS Spacecraft Bus Telemetry APID957 Packet File and stores the reformatted data in SDP Toolkit-compatible ephemeris and attitude files.This processing step is required by the NASA Aqua Level-1 direct broadcast algorithm.Unfortunately, we have not yet been able to fully test the software, butwanted to provide something that the user can begin to integrate into their processing chain as soon as possible, prior to the initialization of the AQUA direct broadcast. This means that this is a beta version and there will likely be a new version of the GBAD software in the near future. The program has been compiled and executed on a LINUX OS. The make files mayhave to be modified for compilation on other platforms. The GBAD download and document web page is:http://directreadout.gsfc.nasa.gov/gbad_frames.cfm Go to the bottom of the page and select GBAD from the software list. You may also use the menus on the left.Test data sets can be found at: ftp://modis-dbc.gsfc.nasa.gov/testdata/aqua/mission2/gbad/ This folder contains input and corresponding output data sets.
