   If you use RTLSDR with demod_asrtu-1_rtlsdr.grc, double click
   on Plan13 CC block to set latitude, longtitude and altitude.
   The software will compensate doppler automaticly.
   Pay attention to frequency offset and gain of RTLSDR.

   If you use a radio with USB IF with demod_asrtu-1_audio.grc,
   select correct audio input device in your system audio config,
   and use a extern software to compensate doppler.

[Re-post from ANS-329] ASRTU-1 Designated ASRTU-OSCAR 123

At the request of Harbin Institute of Technology(Chaina) and Amur State
University(Russia), AMSAT has designated ASRTU-1 as ASRTU-OSCAR 123 (AO-123).

Illustration of AO-123 (Credit: http://nanosats.eu)

ASRTU-1 was launched on November 4, 2024 at 23:18 UTC, on a Soyuz launch
vehicle from Vostochny Cosmodrome, Russia. Built and operated by Harbin
Institute of Technology and Amur State University, the satellite carries a
V/U repeater, UHF SSDV digital image transmitter, and a 10.5 GHz QPSK image
transmitter. All of these payloads have been successfully tested, and the
repeater has been operational for QSOs.

The satellite contains an FM transponder, which is currently operational,
with an uplink of 145.850 MHz (67 Hz CTCSS tone required) and a downlink of
435.400 MHz. After the repeater detects the end of uplink, it will wait for
0.5s. If no new uplink in 0.5s, telemetry will be sent. So make fast QSOs
so the telemetry is less like to interrupt you.

The satellite also contains two cameras with an SSDV downlink for low
resolution images on 436.210 MHz, and a high speed downlink on 10.460 GHz
for high resolution images.

Windows software for decoding telemetry is available at
https://drive.google.com/file/d/1W8nm-P0_h0J1Bd1eif74mLo-EuRdWcjH

Two-Line Keplerian elements (TLEs) may be found at

AMSAT congratulates the Harbin Institute of Technology and Amur State
University, thanks them for their contribution to the amateur satellite
community, and wishes them continued success on this and future projects.

[Re-post from ANS-315] ASRTU-1 Satellite With FM Transponder Launched

On November 4, 2024 at 23:18 UTC, a Soyuz rocket launched from Vostochny
with at least 17 satellites using amateur satellite service frequencies.
Among those launched was ASRTU-1, a 12U CubeSat designed by Russian and
Chinese students and developed by the Harbin Institute of Technology in
Harbin, China, for education and amateur radio.

The satellite contains an FM transponder, which is currently operational,
with an uplink of 145.850 MHz (67 Hz CTCSS tone required) and a downlink of
435.400 MHz. After the repeater detects the end of uplink, it will wait for
0.5s. If no new uplink in 0.5s, telemetry will be sent. So make fast QSOs
so the telemetry is less like to interrupt you.

The satellite also contains two cameras with an SSDV downlink for low
resolution images on 436.210 MHz, and a high speed downlink on 10460.00 MHz
for high resolution images.

On November 7, 2024, the camera system was tested for the first time. N6RFM
uplinked the command and the image was downloaded by Chinese stations using
the UHF SSDV downlink.

Windows software for decoding telemetry is available at
https://drive.google.com/file/d/1W8nm-P0_h0J1Bd1eif74mLo-EuRdWcjH

A Live ISO Linux image is also available for telemetry at
https://drive.google.com/drive/folders/1T6GMNnDNEEavckoe4oPXPIU_SPFXLDd4

A Telegram group has been created for discussing the satellite:
