Headline Details: Comprising of a 3U CubeSat, the Triton-2 mission is a radio science mission which aims to test an experimental advanced AIS (Automatic Identification System)receiver. Telemetry downlinks will be 9k6 RC-BPSK on VHF(145MHz) and 38k4 RC-BPSK on S Band (2400MHz). A telemetry format specification will be made available which will allow amateurs to decode housekeeping and payload telemetry. The satellite includes two secondary amateur radio payloads: A single channel mode U/V (435-145MHz) FM to DSB transponder. Note: since the uplink frequency for the transponder is shared with one of the 2 redundant command uplinks, its frequency will be published after the 3 months of science mission. A single channel mode U/S (435-2400MHz)FM to FM transponder. Note: since the uplink frequency for the transponder is shared with one of the 2 redundant command uplinks, its frequency will be published after the 3 months of science mission. Possibly (power budget permitting), both payloads may be switched on at the same time. Mission duration: Science mission: 3 Months - Amateur radio mission: as long as possible after the science mission finishes. Expected to launch late 2012 on a DNEPR from Yasny together with Triton-1, UKube-1, Delfi n3Xt, Trio-Cinema 1& 2 and other spacecraft using frequencies in the amateur satellite service. The following downlink frequencies have been coordinated: Main Downlink 145.860MHz & Backup Downlink 145.815MHz. The S-band downlink will be 2408.00MHz - The Uplink frequencies will be announced by the project team after launch.
Application Date: 28 Dec 2011   Freq coordination completed on 06 Jan 2012
