FUNcube-1 Team to Gather for November 21 Launch,
« Dashboard » Software Released
Members of the FUNcube-1 team will gather November 21 – launch day – at the RSGB’s National Radio Centre at London’s Bletchley Park to staff a monitoring station at least for the first couple of days following launch. FUNcube-1 is among more than two dozen small satellites – many of them carrying Amateur Radio payloads – that will be put into orbit by a Dnepr rocket now being readied in Russia
« The first signals from FUNcube-1 should be heard in Southern Africa and then in Hawaii and then Alaska, » said a message on the FUNcube-1 website. FUNcube-1 initially will transmit at about 30 mW (« safe mode »), and telemetry will be on 145.935 MHz. In its normal « educational mode, » the signal should to be about 10 dB stronger. « After that, we hope to hear signals in the UK on a very low pass to the east around 0850 UTC. We will be trying to do our best to keep everyone in touch with what is happening, » the message continued. Part of that effort will include streaming video from the NRC, getting underway at about 0700 UTC the day of the launch. The team also will maintain a presence on the #cubesat IRC channel , as well as via the AMSAT-BB.
The first release of the FUNcube Dashboard User Interface software is now available for download. Information can be found on the web.
This software, when used with a FUNcube dongle or other SSB-capable VHF receiver, will decode and display all 58 telemetry channels, all onboard status flags, and the Fitter messages from the spacecraft. « The FUNcube Dashboard will also enable users to upload the telemetry they are receiving to a central data warehouse, so that others around the world can see what is happening onboard, the launch team said. Details of the telemetry format, which reflects considerable heritage from AO-40, also are available, as is the FUNCube Handbook. The FUNcube-1 team also has released information on how to register your dashboard for use with the data warehouse.
