Sounds from Amateur Radio Satellites 2019-today

 

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.

#44354
(2019-036U)

PSat 2 (ParkinsonSAT) is a student satellite project which is a two way communications transponder for relaying remote telemetry, sensor and user data from remote environmental experiments or other data sources back to experimenters via a global network of internet linked volunteer ground stations. The data transponder also includes all telemetry, command and control for a complete cubesat. The PSat-2 is a 1.5U CubeSat.

The unique features of PSAT-2 are the APRS transponder and the PSK31 transponder, both of which flew on PSAT-1 and the new APRStt (TouchTone)/Voice transponder, for which a prototype flies on the eXCITe (QIKCOM-2) satellite, which lets everyone do APRS using any radio with DTMF keypad, not just those with APRS radios.

The callsigns of PSAT2 are PSAT2-1 when it is in safe-mode with the DIGI switched off and the callsign is PSAT2 when the digi is on.

CAS-7B
BP-1B

#44443
(2019-042C)

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)

#44909
(2019-096E)

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. 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, this is presently the highest orbiting functioning amateur satellite available worldwide.

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.

Dec 26th 2019

On May 5th 2020 at 20:25 UTC Robert DL5GAC and Charly DK3ZL hat a successful contact via RS-44. Recording kindly provided by Charly DK3ZL.

Shortly after, on May 5th 2020 at 20:32 UTC I received DL5GAC calling CQ and having another QSO. As I was using only a short vertically polarized omni-directional antenna the signals were quite weak but readable.

During the same path I also received some Italian stations including Rocco in IN70VH and I95TEPM in a QSO.

Charly DK3ZL also kindly sent me a recording of the CW beacon, which he had received on May 5th 2020 at 14:30 UTC.

(1998-067RL)

Guatemala’s first satellite, a 1U CubeSat called QUETZAL-1, was deployed from the International Space Station (ISS) on Tuesday, April 28th 2020 using the Japanese KIBO module.

Its primary mission is to test a sensor for remote data acquisition for natural resource management, which could be used to monitor water quality in inland water bodies.

The satellite is part of the Japanese Kibo cubesat program, a product of the cooperation between, among others, the United Nations Office for Outer Space Affairs (UNOOSA), Universidad del Valle de Guatemala (UVG), and more institutions. The operational frequencies were chosen through cooperation from Guatemalan radio amateurs and the International Amateur Radio Union (IARU).

#47311
(2021-002C)

RadFxSat-2 was launched on January 17th 2021 on a LauncherOne vehicle.

The satellite carries a telemetry beacon and a linear transponder.

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.
