ARISS-Russia FM transmissions from Space Station

A Tanusha CubeSat

On June 20 and 21, the Tanusha satellites will be connected to an antenna on the ISS Russian Service Module and transmit voice messages on 437.050 MHz FM with 145.800 MHz FM relay.

The AMSAT-NA website says:

ARISS-Russia, in collaboration with the Southwest State University in Kursk, Russia, are developing a series of educational CubeSat satellites called Tanusha.

Two Tanusha CubeSats were developed by students at Southwest State University and were hand-deployed by cosmonauts during an August 2017 extravehicular activity. These two CubeSats are performing cluster flight experiments through communications links.

A second set of CubeSats, Tanusha 3 & 4 were launched earlier this year and are currently on-board ISS. Tanusha 3 & 4 are planned to be hand deployed by Cosmonauts in August. They will perform even more comprehensive cluster flight objectives than Tanusha 1 & 2.

On June 20, Tanusha 3 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on 437.05 MHz. These FM transmissions will include greetings from students in several languages, including Russian, English, Spanish and Chinese.

On June 21, Tanusha 4 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on the same frequency: 437.050 MHz.

The ARISS-Russia team plan to also retransmit these signals on the standard ARISS 2-meter downlink, 145.80 MHz using the JVC Kenwood D700 radio that is still on-board ISS. All are invited to listen to the CubeSats from ISS on 437.050 and/or 145.800 MHz FM.

Note: the Doppler shift for the 437.050 MHz signal will be +/-10 kHz.

Ofcom Consultation: World Radiocommunication Conference 2019

Ofcom has published a consultation on the UK’s preparations for the World Radiocommunication Conference 2019 (WRC-19) of the International Telecommunication Union.

WRCs are held approximately every four years, and take decisions concerning the identification and international harmonisation of spectrum bands. Ofcom represents the UK at WRCs.

The next conference will take place between October 28 and November 22, 2019. It will consider a wide range of issues across a number of sector interests including mobile broadband, maritime, aeronautical, satellite and scientific use of spectrum.

The public consultation closes on September 13, 2018, details at

Russian SiriusSat CubeSats to be deployed during spacewalk

SiriusSat-1 RS13S and SiriusSat-2 RS14S CubeSats

SiriusSat-1 (RS13S) and SiriusSat-2 (RS14S) CubeSats

It is planned that two Russian CubeSats will be deployed from the International Space Station in August during a spacewalk (EVA).

SiriusSat-2 (SXC1-182) call sign RS14S beacon 435.670 MHz

The satellites are at RSC Energia, where they are undergoing additional checks before being sent to the International Space Station. A launch is planned for July 10 on a Progress cargo vehicle to the ISS with deployment in August during a spacewalk.

Bulgarian CubeSat EnduroSat on ISS awaiting deployment

EnduroSat One

EnduroSat One

Bulgaria’s first CubeSat, EnduroSat One, was launched to the International Space Station on the cargo resupply OA-9 mission on May 21, 2018 from the Mid-Atlantic Regional Spaceport in Virginia, USA. On May 24 the Cygnus capsule docked to the Station and the satellite was taken onboard the ISS.

The satellite will be deployed from the ISS in the coming weeks.

The mission aims to popularize the Radio Amateur activities in Bulgaria and it will include cooperation with Bulgarian Federation of Radio Amateurs (BFRA), including workshops and additional educational activities.

The spacecraft has been completely built in Bulgaria. This first educational mission aims to inspire young Bulgarians and give them the chance to participate in a real space program!

The Space Challenges and EnduroSat teams have invested considerable resources, time and effort in preparing the Bulgarian CubeSat. In order to support the Radio Amateur community, the satellite emits in frequencies which are readily available for receiving by anyone with basic communication skills and radio equipment.

It is hoped the mission will help more young Bulgarians learn the basics of satellite communications through practical exercises empowered by the orbiting satellite.

Radio amateurs from around the Globe will be able to listen to the satellite beacon and to receive telemetry data from the satellite on a regular basis. They will be able to connect to the satellite, receive detailed telemetry information and receive a confirmation from the satellite for every established connection which will serve as QSL card.

Beacon: 437.050 MHz CW and 9600 bps GMSK AX.25
