GBS IOTE Feed Measurements

摘要

The Ka-Band (30/20 GHz) terminal was used to conduct I, O, T, and E of the Global Broadcast System (GBS) package on UHF Follow-on (UFO) satellites, flights 8, 9, and 10. This terminal has been transferred to Lincoln Laboratory through the Milsatcom Joint Program Office at the USAF Space and Missile Center (AFSMC). At Lincoln Laboratory, the terminal is to be evaluated for possible use in on-orbit checkout/experimentation with the Ka-band portion of the Wideband Gap Filler Satellites (expected to launch in 2004). These satellites use the government 20.2-21.2 GHz (downlink) and 30-31 GHz (uplink) frequency allocations. This report describes the test and evaluation of the Ka-Band Terminal dual frequency feed at Lincoln Laboratory's Antenna Test Range and identifies some deficiencies that will need to be addressed prior to use with the Wideband Gapfiller system.
