More than a million UVQSat telemetry frames received

AMSAT-F have issued an update on the UVQSat CubeSat, they plan to conduct further test on the FM transponder.

In a post to the AMSAT Bulletin Board the AMSAT-F President Christophe Mercier says:

More than 1,200,000 frames have been received on the AMSAT-F experimental database this week https://amsat.electrolab.fr/

It is possible to visualize the data via an online Dashboard:
https://amsat.electrolab.fr/grafana/d/ujwd-SaMz/uvsqsat?orgId=1

These data were collected by more than 50 stations in the world via the UVSQsat decoder software. The software allows to send the data to the AMSAT-F and Satnogs databases. The continuous reception of telemetry is valuable to the project team that is piloting the satellite.

Although the downloading of large amounts of data is done over Europe, this also took place over Japan with the help of Japanese radio amateurs.

It is noted that a new version of the UVSQSAT Decoder software is available with new features (new ASCII telemetry decoded, performance improvement,..)

The commissioning phase has been successfully completed. Now the UVSQsat project team with Radioclub F6KRK and AMSAT-Francophone will conduct further tests on the transponder to ensure that it can be operated over a period of several days without taking any risk to the satellite.

For this we are looking for volunteer radio amateurs to participate in these tests on all continents. If you are interested contact AMSAT-Francophone, email amsatf<at>amsat-f.org

Soyuz‑2.1a launch – Amateur radio satellites deployed

Soyuz 2.1a Launch March 22, 2021 – Credit GK Launch Services

The Soyuz‑2.1a LV was launched from Baikonur in Kazakhstan on March 22, 2021. The following satellites, operating in frequency bands allocated to the amateur satellite service have been coordinated by the IARU Satellite Frequency Coordination Panel:

• Beesat‑5
• Beesat‑6
• Beesat‑7
• Beesat‑8
• FEES
• SMOG
• GRBAlpha
• KSU_Cubesat
• DIY‑1
• STECCO
• CubeSX-HSE
• CubeSX-Sirius-HSE
• Orbicraft-Zorkiy
• NanoSatC-BR2

Operating in frequency bands allocated to the amateur satellite service without IARU frequency coordination is KMSL. Additional satellites may follow.

Operating in frequency bands allocated to the amateur satellite service while the IARU Satellite Frequency Coordination Panel has declined coordination are UNISAT‑7 and WildTrackCube-Simba.

Amateur radio satellites deploy March 14

Eight satellites, all coordinated by the IARU Satellite Frequency Coordination Panel, are planned to be deployed from the International Space Station on Sunday, March 14.

The deployment should be streamed live on YouTube, watch from 09:15 GMT at
https://www.youtube.com/watch?v=vLltILh8SLw

The CubeSats being deployed are:
• OPUSAT-II
• GuaraniSat‑1 (BIRDS‑4)
• Maya‑2 (BIRDS‑4)
• Tsuru (BIRDS‑4)
• RSP-01
• WARP-01
• TAUSAT‑1
• STARS-EC

It is understood the BIRDS-4 satellites are carrying digipeaters and TAUSAT‑1 has an FM transponder. Further information including the IARU coordinated frequencies are at http://amsat.org.uk/iaru/

On Friday, March 5, 2021, the first contact was made via the FM transponder on the UVSQ-Sat CubeSat.

Michel Mahé F4DEY of the F6KRK Radio Club carried out the transponder test from the LATMOS ground station. The first contact was with Peter Goodhall 2M0SQL in Elgin.

After the contact Michel tweeted “Very happy to have been able to operate the Latmos station and do #F6KRKR/P validate the transponder #UVSQSat “on #space” after validation of the satellite at the Lab of #Latmos in October 2020!”

Peter tweeted “Fantastic to be QSO #1 on UVSQ-SATs FM transponder wish the @uvsqsat good luck in their commissioning and it being available more often :)”

23cm band in the spotlight with regulators

RNSS – Credit IARU Region 1

The Chair of IARU Region 1 Spectrum Affairs, Barry Lewis G4SJH, reports on the meeting of the ITU‑R Working Party 4C (WP4C) on February 15-19 which discussed the amateur radio allocation at 1240-1300 MHz.

On the IARU Region 1 site he writes:

During the week February 15–19, the preparatory work for WRC-23 agenda item 9.1b continued in ITU‑R Working Party 4C (WP4C). The WRC agenda item has initiated technical studies on coexistence between the radio navigation satellite service (RNSS) and the amateur services in the 23cm band. As usual, the IARU participated in the meeting and delivered key information on amateur activities in this important microwave band. This information is vital to ensure the amateur services are realistically represented in the studies as they move forward.

It remains vital that national amateur communities present their views on the importance of this band to their national regulators in a consolidated and consistent manner.

To assist with this the IARU-R1 is developing supporting material that member societies can refer to when addressing the topic with their national regulator.

The work on this topic will continue throughout the year and beyond both in ITU‑R and in the regional telecommunications organisations and the IARU is committed to ensure every organisation understands the amateur position on this important microwave band.

The ITU‑R WP4C Summary Meeting Report notes “The only administration that can be considered supportive towards proper treatment of the Amateur Services in this work is Germany”, read the report at https://www.iaru-r1.org/wp-content/uploads/2021/02/Report-from-WP4C_Feb-2021.docx
