JY1SAT launch information & Dashboard

by on November 15, 2018

JY1Sat is an enhanced 1U FUNcube. It has been developed for the Crown Prince Foundation in Jordan. The spacecraft has been named in honour of the Crown Prince’s grandfather, King Hussein, who operated using his personal amateur radio callsign which was simply JY1.jy1-sat-cubesat

 In addition to the usual suite of FUNcube capabilities it will also be capable of downlinking images in SSDV format.  This image format, developed by Phil Heron, MI0VIM, for use in High Altitude Balloons, is now also being used from lunar orbit by AO-94.

The telemetry downlink frequency is 145.840 MHz, this will use the usual FUNcube standard 1k2 BPSK format. For the linear transponder the frequencies will be downlink 145.855-145.875 MHz and uplink on 435.100-435.120 MHz. The transponder is inverting so LSB should be used on the uplink.

A new Dashboard has been developed for this mission and is available from  download here:

This will operate in exactly the same manner as those developed for previous missions and general set-up information can be downloaded here: Dashboard Guidance

A brand new Data Warehouse has also been created. This can be used to view the telemetry from ALL of the FUNcube missions. This can his can viewed here http://data.amsat-uk.org

This mission will be one of the payloads on the Spaceflight SSO-A mission which is now expected to launch from the Space Launch Complex-4E at Vandenberg Air Force base in California on Monday, Dec. 3, with a launch window of 18:32 UTC. to 19:01 UTC .  This launch is expected to have more than sixty other payloads. The deployment time for JY1SAT has been advised as 4 hours 31 minutes and 54.5 seconds after launch. This means that, allowing for the pre-programmed delay of 30 minutes between deployment from the POD and the release of the antennas, the first downlink signals cannot be expected until approximately 23.34 UTC on Dec 3rd.

Here is the final telemetry data pack JY1SAT_Data_budget with tlm equations 2F for those who wish to develop their own decoders.

These are provisional pre-launch TLEs for the revised launch date. They should be accurate for at least the first few orbits.

Initial indications are that the spacecraft will be over NE Australia at power-up.

The start-up mode, as usual, is low power telemetry only and we will be really looking forward to receiving reports  and telemetry. So please, either upload the data from the Dashboard to the Warehouse in the usual way, or send a quick email to operations@funcube.org.uk
