JY1SAT (JO-97) carrying the FUNcube-6 amateur radio transponder and ESEO with the FUNcube-4 transponder were launched on December 3, 2018.

JY1SAT – Although not finally confirmed, good tracking results are being obtained using the TLEs for object 2018-99AX / 43803, the 1200 bps BPSK telemetry beacon is on 145.840 MHz.

Commissioning of the spacecraft is continuing and there may be some changes to the operating modes over the next couple of weeks. Please continue to let the Data Warehouse have as much data as possible. In that regard, an updated version of the JY1SAT Dashboard (ver 1189) has just been released. This fixes a couple of buggettes relating to Doppler tracking over multiple orbits and the graph displays now no longer start at zero. This update v1189 JY1 Dashboard can be downloaded from https://download.funcube.org.uk/JY1Sat_Dashboard_v1189.msi

ESEO – In a similar manner to JY1SAT, the official confirmation has not been received, but the best TLEs are currently 2018-99AL / 43792. The 9600 bps downlink signal on 437.00 MHz is quite strong and reports and recordings are welcomed. Please continue to check the https://www.esa.int/Education/ESEO website for the latest updates from ESA.

We can confirm that the AMSAT payload with a downlink on 145.985 MHz has not yet been activated and that DK3WN and EA4GPZ, working with other collaborators, have developed a decoder for the 437.00 MHz downlink signals.

It is hoped that a UI, to show the actual telemetry values, will also be available soon.
