SB SAT @ AMSAT $ANS-187.01 ECHO Progress Update - 05 July 2004 AMSAT News Service Bulletin 187.01 From AMSAT HQ SILVER SPRING, MD. July 5, 2004 To All RADIO AMATEURS BID: $ANS-187.01 The first sets of Whole Orbit Data (WOD) from the satellite have been collected and analysis is continuing. Jim White, WD0E, says, "We have looked at the WOD collected after we adjusted the solar panel set point to what we determined would be close to the optimum point. It resulted in nearly double the peak power input from the panels on the following orbit." Currently the solar panels are producing nearly 20W peak, 16W average in the sun. The WOD shows that ECHO's attitude motion is complex. The torque rod is clearly magnetized with the polarity that has the -Z down in the northern hemisphere. The Command Team would like to thank everyone that has sent in ECHO telemetry to date. The data has already proven useful in the commissioning effort. A new web page is now available for submitting telemetry data. The web page also includes options for retrieving and graphing archived telemetry data. The new ECHO telemetry archive web page is http://www.coloradosatellite.com/echo The TlmEcho program has an updated coefficients file available and version 1.03 will be available for downloading on 06 July 2004 from http://www.amsat.org/amsat-new/echo/tlm_decode.php [ANS thanks Jim, WD0E and Mike, KE4AZN for the above information] /EX
