During weekends\n(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.\n\nWhen the transponder is switched off, the telemetry beacon is on full power,\nwhen the transponder is on the beacon it is on low power. During holidays,\neg Christmas, New Year, Easter, etc, the transponder maybe activated for\nextended periods. Watch AMSAT-BB for announcements which are usually made on\nFriday evenings (UTC)\n\nThe nominal transponder frequencies are:\n\nUplink: 435.150 - 435.130 MHz LSB (Inverting)\nDownlink: 145.950 - 145.970 MHz USB\nTelemetry Tx: 145.935 MHz BPSK\n\n(The passband may be up to 15kHz higher depending on on-board temps. Lower\ntemperatures give higher freqs!)\n\nFUNcube-2 (aka FUNcube on UKube)\n\nThe FUNcube-2 sub-system continues to operate autonomously and, almost\ncontinuously, in amateur mode. The transponder is operational and the\ntelemetry downlink is functioning with about 70mW output. The FUNcube-1\nDashboard does not correctly display the telemetry but it does correctly\ndecode the data and uploads it to the FUNcube Data Warehouse from where it\ncan be examined. Most of the real time data channels are operational and\nthese include battery voltages, temperatures and ADCS data coming via the\nmain On Board Computer (OBC).\n\nThe transponder is interrupted for a few seconds every 2 minutes when the\nother transmitter sends its CW beacon and, occasionally, for a few seconds\nwhen the main OBC reboots (approx seven times each orbit).\n\nThe nominal transponder frequencies are:\nUplink: 435.080 - 435.060 MHz LSB (Inverting)\nDownlink: 145.930 - 145.950 MHz USB\nTelemetry Tx: 145.915 MHz BPSK\n\n(The passband may be up to 10kHz higher depending on on-board temps. Low\ntemperatures give higher freqs!)\n\n\nEO79 FUNcube-3\nDue to power budget constraints the transponder cannot be operational 24/7\nand an orbit specific schedule has been developed. The transponder will\ncommence operation 27 minutes after the spacecraft enters sunlight and will\nstay on for a period of 25 minutes. This schedule may be modified in future\nmonths as a result of experience.\n\nThe nominal transponder frequencies are:\nUplink: 435.0723-435.0473 MHz LSB (Inverting)\nDownlink: 145.946-145.971 MHz USB\n\nFurther detailed info on EO79 transponder frequencies is at:\nhttps://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/\n\n\nEO88/Nayif-1/FUNcube-5\n\nEO88 is presently operating in autonomous mode. The transponder is\noperational when the satellite is in eclipse, ie the solar panels are NOT\nbeing illuminated.\nWhen the transponder is switched off, the telemetry beacon is on full power,\nwhen the transponder is on the beacon it is on low power.\nThe transponder frequencies are:\n\nUplink: 435.045 – 435.015 MHz LSB (inverting)\nDownlink: 145.960-145.990 MHz USB\nTelemetry Tx: 145.940MHz\n\nAll FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very\ngrateful for the assistance given by Innovative Solution In Space Bv, The\nNetherlands.\n\n_______________________________________________\nSent via [email protected].
