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

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.

AMSAT-UK at the UK Space Conference July 4/5th 2011

UK Space Conference 2011AMSAT-UK will have a presence at the first ever UK Space Conference taking place at the Univeristy of Warwick on July 4/5th. This is being organised by the UK Space Agency which was formally commenced in April this year.

We have been sponsored by a member to have a small stand “booth” in the exhibtion area and will be amongst  some very illustrious company.

We will be displaying FUNcube models and demonstrating the educational outreach possibilities that we will have with the telemetry and Fitter message download systems when matched with a simple groundstation – the FUNcube dongle.

We will also  be presenting short papers in the educational and cubesat streams during the event.

Rosetta’s hibernation mode starts today (8th June 2011) and will last until January 2014, during which time the spacecraft will reach its maximum distances from the Sun (about 800 million kilometres) and Earth (about 1000 million kilometres). UK scientists and engineers involved in this exciting mission are hoping Rosetta will unlock the hidden secrets of comets and teach us more about the origin of these huge, dirty snowballs.

Rosetta’s primary mission hasn’t even started yet but since the launch in 2004 it has been on a non-stop cosmic ‘road-trip’ Continue reading
