Ground stations are invited to continue uploading received telemetry for the life of the satellite. “or the next 72-96 hours at least, as we look for successful startup, watch the general health and function as the satellite begins to acclimate to space, and perform the on orbit checkout,” Buxton said. Telemetry should begin about 55 minutes after deployment. He said AMSAT command stations will want to see voltage and current data to determine that the spacecraft is healthy and to conduct various tests before opening it up for general use. Satellite and experiment telemetry will be downlinked via the DUV subaudible telemetry stream, which can be decoded using FoxTelem software.ĪMSAT Vice-President Engineering, Jerry Buxton, N0JY, said RadFxSat/Fox-1B will automatically come up in beacon mode, transmitting a beacon and voice ID (“RadFxSat Safe Mode”) every 2 minutes, starting about 50 minutes after deployment. It will carry a Fox-1 style FM U/V repeater with an uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz. RadFxSat is a partnership with Vanderbilt University’s Institute for Space and Defense Electronics ( ISDE) and hosts four payloads for the study of radiation effects on commercial off-the-shelf components. RadFxSat is one of four CubeSats making up the NASA ELaNa XIV mission, riding as secondary payloads aboard the Joint Polar Satellite System (JPSS)-1 mission, which will launch from Vandenberg Air Force Base, California. The launch now is scheduled for no earlier than Tuesday, November 14. The launch of the Delta II vehicle carrying RadFxSat (Fox-1B) and other payloads has been delayed, due to a faulty battery on the booster, United Launch Alliance (ULA) announced on November 6.
