Bulgarian First CubeSat Deployed from ISS

Bulgaria's first CubeSat, EnduroSat One, was launched to the International Space Station on the cargo resupply OA-9 mission during May 2018 from the Mid-Atlantic Regional Spaceport in Virginia, USA  

On 24th May 2018 the Cygnus capsule docked to the Station and the satellite was taken on board the ISS and will be deployed 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

ISS SSTV Active Early June

The International Space Station (ISS) amateur radio Slow Scan Television (SSTV) transmissions on 145.800 MHz FM are expected to be activate 6th and 7th June 2018

The Inter-MAI-75 SSTV experiment should be active on:
• Wednesday 6th June 2018 from 12:30-16:30 UT
• Thursday 7th June 2018 from 11:50-15:25 UT

The SSTV images will be transmitted on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is expected they will use the PD-120 SSTV format.

Linear transponder CubeSat Deployed from ISS

JAXA has announced three CubeSats, Irazu (Costa Rica), 1KUNS-PF (Kenya) and UBAKUSAT (Turkey) were deployed from the International Space Station on Friday 11th May 2018 between 1030-1040 GMT

All the CubeSats carry amateur radio payloads, Irazu and 1KUNS-PF have telemetry beacons while UBAKUSAT carries a linear transponder for amateur radio SSB and CW communications in additional to CW and telemetry beacons.

 

Irazu is a 1U CubeSat developed by students at the Costa Rica Institute of Technology Telemetry - Beacon 436.500 MHz

1KUNS-PF is a 3U CubeSat developed by students at the University of Nairobi - Telemetry Beacon 9600bps 437.300 MHz

UBAKUSAT is a 3U CubeSat developed by students at the Istanbul Technical University

CW Beacon 437.225 MHz
Telemetry Beacon 437.325 MHz

Linear Transponder

• 435.200-435.250 MHz downlink
• 145.940-145.990 MHz uplink
