It’s time to get ready for ARISSat-1

It’s time to get ready for ARISSat-1

A few weeks remain before the planned July deployment of ARISSat-1 from the ISS.

ARISSat-1

Here are some reminders to help you get your station ready for ARISSat-1 operation.

145.950 MHz FM Downlink:
FM transmissions will cycle between a voice ID as RS01S, select telemetry values, 24 international greeting messages in 15 languages and SSTV images. One of the messages will be a conversation between Yuri Gagarin and ground control. See the next news item for pointers to get your station ready to receive the SSTV images.

435 MHz – 145 MHz Linear Transponder:
The linear transponder will operate in Mode U/V (70 cm Up, 2m Down).
It is an 16 KHz wide inverting passband and the convention will be to TX LSB on the 435 MHz uplink and RX USB on the 145 MHz downlink. This mode is designed to work with low power transmitters and omni antenna.

145.919 MHz/145.939 MHz CW Beacon:
The CW transmissions will be callsign ID RS01S, select telemetry, and callsigns of people actively involved with the ARISS program.

College congratulated on ISS ham radio link-up

Lough Erne Amateur Radio Club congratulates South West Regional College on its very successful Amateur Radio link up with the International Space Station.

Particular credits to Mamraz Nagi whose initiative secured this ARISS event, the College technicians, and the students who spoke with the Radio Amateur in the ISS, Ronald J Garan, KF5GPO. Among his replies to the Enniskillen students’ questions, he shared very happy memories of a recent visit to Northern Ireland.

David Taylor operated the ground station K6DUE in Maryland USA linking up to the ISS, and Gaston Bertels ON4WF in Belgium, guided the College ARISS team through checks, rehearsals student questions and wrapped up with remarks that brought massive applause from over a hundred present for the radio amateurs in space and on the ground, and all involved in Northern Ireland’s first ever ARISS event.

ARISSat-1 Reception Challenge

ARISSat-1 is scheduled for deployment from the ISS next Wednesday Feb 16 – it has a composite VHF downlink that will easily fit into the FUNcube Dongle receive spectrum. The telemetry is 1 kbit BPSK and can, of course, also be received with a normal SSB 2 metre receiver.

The expected signal levels from ARISSat should be similar to those we expect from FUNcube itself (and also eventually  from UKube) and the team are keen to discover what will be the minimum and best type of antennas for schools to use with a FCD. Therefore user experience with the ARISSat signals will be very valuable in making this determination.
