Sounds from Amateur Radio Satellites 2019-2022

 

This section is dedicated to satellites built and operated by Radio Amateurs. Satellites built by AMSAT organizations around the world and were called AMSAT-OSCAR. Those built by Russian Hams and were mostly called Radiosputnik. In order to build and launch the satellites AMSAT needs members and friends to contribute and raise funds. If you are not yet a member of AMSAT please consider to join us and to support the activities. You can find several links to AMSAT on my links page.

CAS-7B (BP-1B) was launched on July 25th 2019 by a Hyperbola-1 launch vehicle from the Jiuquan Space Center, China into a circular orbit with a height of 300km and an inclination of 42.7 degree. This microsatellite was developed by the Chinese Amateur Satellite Group (CAMSAT) in cooperation with the Beijing Institute of Technology (BIT). CAMSAT completed the project planning, design, build, and testing, and manages the on-orbit operation of the satellite. BIT provided the satellite environmental testing, launch support, and financial support. Many students from BIT were involved in the project, learning about satellite technology and amateur radio. The satellite carries a CW telemetry beacon and FM repeater that has been active since launch. Because of the orbital apogee and the size and mass of the satellite, the orbital life of the satellite is expected to be only one week, up to a maximum of one month, which will also provide with an opportunity for hams to track and monitor satellite entering the atmosphere.

The CW telemetry beacon us transmitting on 435.715 MHz (100mW).
The V/U FM transponder uplink frequency is 145.900 MHz.
The V/U FM transponder downlink frequency is 435.690 MHz (100mW)

Constructed by specialists at Information Satellite Systems and Students at Siberian State Aerospace University, DOSAAF-85 was launched together with 3 Gonets satellites and BLITS-M1 on a Rockot/Breeze-KM launch vehicle from Plesetsk Cosmodrome on December 26th 2019. The satellite failed to separate from the upper stage of the launch vehicle and remains attached. The satellite’s name commemorates the 85th anniversary of the Voluntary Society for the Assistance to the Army, Aviation, and Navy (DOSAAF), the organization responsible for the military training of Soviet youth.

Designated RS-44, or Radio Sputnik 44, the satellite carries a 60 kHz wide inverting V/U linear transponder and a CW beacon.

The uplink and downlink frequencies of the inverting transponder are:
Uplink: 145.935-145.995 MHz LSB
Downlink: 435.610-435.670 MHz USB

Beacon: 435.605 MHz CW

It may also have a S-band downlink between 2400 and 2485 MHz.

With an orbit of 1511 km x 1175 km and an inclination of 82.5 degrees, RS-44 is providing a nice footprint given it is a LEO satellite.

The transponder was first time activated on April 30th 2020 for a test period until May 11th 2020. It seems to work very well and hopefully will stay active for a longer period of time.

Its beacon downlink is supposed to be at 435.750 MHz and the linear transponder downlink 435.760-435.790 MHz.

The beacon was never heard but there were a few reports that weak downlink signals were heard on the transponder.

I have contacted those reporters and the responsible people at AMSAT-NA and asked for recordings to add them to this collection but never received any answer.

After 6 months, on July 20th 2021, the satellite was officially released for general use .Maybe now audio recordings might become available.

OPUSAT-2
Hirogari

#47930
(1998-067SG)

OPUSAT-2 (Osaka Prefecture University Satellite) or Hirogari is a 1.4KG nanosatellite that was developed by Osaka Prefecture University. It was developed based on the earlier OPUSAT. The 2U Cubesat was launched on board of Cygnus CRS-15 on an Antares-230+ rocket and was thus delivered to the ISS, from where it was deployed via the JEM airlock.

OPUSAT 2 has two main missions:

The first mission is to demonstrate high-speed data transmission in amateur radio band. The satellite communication system's design and the results of the experiment will be made public.

The second mission is a deployment of a large folded structure. A deployable plastic plate is stored inside the satellite, based on Miura fold. The folding method that will be tested in this mission takes into account the thickness of the plate, unlike the traditional Miura fold. The satellite will optically measure the deployment using a pair of cameras. The team proposes applying this folding method on space-based solar power in the future.

Hirogari uses the following amateur radio frequencies and modes:

Downlinks:
145.900 MHz - CW beacon
145.900 MHz - AFSK 1200bd AX.25 / GMSK 9600-13653bd AX.25

Uplink:

The CAMSAT XW-4 (CAS-10) satellite was launched into the Chinese Space Station on November 12th 2022 aboard China's Tianzhou-5 cargo spacecraft, and was launched by the Long March-7 Y6 launch vehicle from the Wenchang Launch Center in Hainan, China. It is currently planned that the XW-4 (CAS-10) satellite will be separated from the Chinese space station and enter operational orbit at 01:30 UTC on December 18th 2022.

The functions of XW-4 (CAS-10) satellite include UHF CW telemetry beacon, GMSK telemetry data transmission, V/U mode linear transponder and a visible light band space camera.

After the satellite completes the in-orbit test and works normally, the space camera photo download will be open to amateur radio enthusiasts all over the world. When the relevant remote control command is received by the satellite, the GMSK telemetry channel will be used to downlink the photo storage information and photo data, and the telemetry data will stop sending at that time.

XW-4(CAS-10) satellite adopts a 8U CubeSat structure with a mass of about 12kg, an on-orbit envelope size of 1007x790x475mm with four solar array panels and a three-axis stabilized attitude control system is used, long-term power consumption is about 18.3 Watts.
