An updated evaluation of space TWT gain change over life
TWT gain variation over life continues to be of major interest to telecommunication satellite operators. A study was published for IVEC 2007 [1], demonstrating that under certain conditions, such gain change could be detected using available spacecraft level telemetry. This paper provides an update, with two areas of concentration: Area 1: Comparison of measurements in 2011 against the projected performance using data in 2007. Area 2: Evaluation of newer space TWTs to determine if similar trends are seen.
