SiriusSat-2 (SXC1-182) RS14S beacon 435.670 MHz
(signal reported Aug 15 https://network.satnogs.org/observations/?norad=99971)

Tanyusha SWSU №3 RS-8 beacon 437.050 MHz 9k6 FSK or FM voice
(signal reported Aug 15 https://network.satnogs.org/observations/?norad=99974)
Tanyusha SWSU №4 RS-9 beacon 437.050 MHz 9k6 FSK or FM voice
(signal reported Aug 15 https://network.satnogs.org/observations/?norad=99973)

The Tanyushka SWSU CubeSats are also referred to as Tanyusha-YuZGU or Tanusha. The Cryillic spelling is Танюша-ЮЗГУ.

Was ТNS-0 №3 (Technologicesky Nanosputnik) deployed along with the four CubeSats?

BIRDS-2 CubeSats to deploy from ISS August 10

BIRDS CubeSat Project LogoMasa JN1GKZ reports JAXA has announced three BIRDS-2 CubeSats with APRS digipeaters will deploy from the International Space Station at about 0945 GMT on August 10, 2018.

BHUTAN-1, MAYA-1 and UiTMSat-1 will transmit 30 minutes after deployment. Initial mode looks CW on 70cm.

They use same frequency 437.375 MHz and transmit in the order of BHUTAN-1, MAYA-1 and UiTMSat-1. Each CubeSat also has an APRS digipeater on 145.825 MHz.

Watch BIRDS-2 deployment live broadcast at https://www.youtube.com/watch?v=pwS5uE5RStw

Satellite      Country      ID             Call Sign
BHUTAN-1  Bhutan       BIRD-BT   JG6YKL
MAYA-1      Philippines  BIRD-PH  JG6YKM
UiTMSat-1  Malaysia     BIRD-MY  JG6YKN

The live broadcast will open on 0915-1010z August 10. Deployment will be done around 0945z.

Initial operation plan is announced as following.
T=0  deployment form ISS
T+30  V/U antenna deployment
T+32  437.375MHz CW beacon start transmitting

So, CW beacon will start 1017z. The location is over Central Asia. Satellites go towards the east and pass through China, Japan, Pacific Ocean, South America, Africa and Europe. Check the orbit with ISS keps.

Masa JN1GKZ reports JAXA has announced that nine CubeSats will deploy from the International Space Station on Friday, July 13.

The nine CubeSats are RainCube, Radix, CubeRRT, HaloSat, TEMPEST-D, EnduroSat AD, EQUISat, MemSat and RadSat-g.

EnduroSat AD, EQUISat and MemSat will operate in the amateur bands. The IARU Amateur Satellite Frequency Coordination Status pages show these frequencies:
• EnduroSat AD 437.050MHz CW, GFSK 9k6
• EQUISat 435.550MHz CW, FSK 9k6
• MemSat 437.350MHz BPSK 9k6

Happy chasing!

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
