Upcoming ARISS-Russia Voice Greetings, SSTV Transmissions from the ISS

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:  437.05 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 437.05 and/or 145.80 MHz.

The next SSTV image downlinks are planned for June 29-July 1.  These images will commemorate the various satellites that the ARISS team has developed and hand-deployed from the ISS.  These will include the first satellite deployment from ISS:  SuitSat-1/Radioskaf-1 which was deployed in February 2006.  More details on this will be forthcoming as the date draws near.

CAMSAT Submits Frequency Coordination Requests for 3 Satellites Scheduled for September 2018 Launch

CAMSAT, the Chinese Amateur Satellite Group, has submitted requests to the IARU for frequency coordination for three new amateur satellites.

CAS-5A is a 6U CubeSat with several amateur transponders: A 30 kHz wide 15 meter to 10 meter linear transponder, a 15 kHz wide 15 meter to 70 cm linear transponder, a 30 kHz wide 2 meter to 70 cm linear transponder, and a 2 meter to 70 cm FM repeater. The satellite also has 10 meter and 70 cm CW beacons as well as a 70 cm 4.8k / 9.6k GMSK telemetry downlink.

CAS-5B is a 90 mm L x 80 mm W x 50 mm H 0.5 kg femtosatellite with a 70 cm CW beacon.

CAS-5A and CAS-5B are scheduled to launch in September from Jiuguan Launch Center into a 539 km x 533 km 97.5 degree inclination orbit.

CAS-6 is an amateur payload aboard a 50 kg microsatellite with a 20 kHz wide 70 cm to 2 m linear transponder, a VHF CW beacon, and a 4.8k GMSK telemetry downlink. Launch is planned from a Sea Launch Pad from the China Academy of Launch Vehicle Technology in September into a 579 km x 579 km 45 degree inclination orbit.
