AMSAT-UK test ESEO payload command uplink

AMSAT-UK are providing an amateur radio 1260/145 MHz FM transponder and a
145 MHz BPSK telemetry beacon for the* European Student Earth Orbiter*
(ESEO) satellite

Over the weekend of April 22-23, 2017, AMSAT-UK members met at the Surrey
Space Centre to conduct some final testing of the command uplink on the
Engineering Model of their payload which will launch on the European Space
Agency ESEO mission.

The payload, which will transmit 1k2 and 4k8 BPSK telemetry on 145.895 MHz,
was set up in the Arthur C Clarke building, with the AMSAT-UK team sending
commands on L-band (1260 MHz) from some distance away in the university
grounds.  A large string of attenuators simulated the path loss to low
Earth orbit, while the VHF telemetry confirmed the level of signal received
at the 'spacecraft antenna' and that the commands had been executed
correctly.

With the lab and range testing declared a success, work now begins on
constructing the Flight Model hardware. This is due for delivery by the
middle of the summer so that it can be integrated into the 50 kg microsat.
ESEO is expected to be launched late this year or in the first quarter of
2018.
