Published flight manifests indicate that the Chinese amateur radio
satellite ASRTU-1 has been scheduled for launch in November of this year
aboard a Russian rocket. As always, launches are subject to a wide variety
of variables, and space agencies are not always 100% forthcoming about
their activities. So while you may not want to mark the calendar just yet,
hopeful signs are pointing toward a launch in the coming months.
*ArtistâÖs sketch of ASRTU-1*
ASRTU-1 is a 12U Cubesat mission designed by Russian and Chinese university
students for education and amateur radio. Harbin Institute of Technology
has successfully developed several amateur radio satellites, including
LilacSat-2 (CAS-3H), LilacSat-1 (LO-90), DSLWP-A (LO-93) and DSLWP-B
(LO-94). The partner institution is Bauman Moscow State Technical
University, which constructed two satellites, Baumanets-1 in 2006 and
Baumanets-2 in 2017, both of which unfortunately failed to reach orbit due
to launch failures unrelated to the satellite payloads.
The amateur radio station onboard ASRTU-1 will provide FM and telecommand
uplinks, as well as FM, telemetry, and digital image downlinks. A new SDR
based transceiver was developed to provide communication and experimental
resources to radio amateurs, including a V/U FM transponder, a UHF
telemetry downlink, and a 10.5G image downlink.
The repeater uplink will be on 145.875 MHz FM using a 67 Hz CTCSS (PL)
tone. Downlink will be on 435.400 MHz FM. The telemetry beacon will be on
436.210 MHz using 9k6 bps BPSK.
In addition to the FM repeater, the satellite will also provide an open
telecommand system to allow radio amateurs to send commands to control the
satellite to take and download images. X Band image downloads using 1
Mbps/10mbps QSPK will downlink on 10.460 GHz.
ASRTU-1 has been scheduled for a Roscosmos launch from Vostochny
Cosmodrome, Asiatic Russia, in Q4 2024 into a 530 km Sun-synchronous Orbit
(SSO). Downlinks and the repeater uplink have been coordinated by the
International Amateur Radio Union (IARU).
