Satellite Operating in TX Factor Show

Amateur radio satellite operating featured in episode 12 of the popular TX Factor Show.

In this episode Bob McCreadie G0FGX teaches Mike Marsh G1IAR a thing or two about amateur satellite operating.

The show highlights the book – Getting Started with Amateur Satellites – which is available from the AMSAT-UK shop at http://shop.amsat-uk.org/

Amateur Radio BIRDS CubeSat Constellation

BIRDS CubeSat Engineering Model integration test

The BIRDS constellation, planned to deploy from the ISS in 2017, will consist of four 1U CubeSats (BIRD-B, BIRD-J, BIRD-G and BIRD-M). They are made of the exactly same design including the radio frequencies to be used and will be deployed together.

BIRDS CubeSat Project LogoThe main mission of the constellation is to do experiments on radio communication with a CubeSat constellation via a network of UHF/VHF amateur radio ground stations all over the world.

The challenge is to distinguish each satellite from the four satellites transmitting with the same frequency, hand over operation of a satellite from one ground station to another and assemble the satellite data, such as housekeeping telemetry, music and the Earth images, obtained at different ground stations.

Amateur radio enthusiasts are asked to join the network to assist in the data downlink and reconstruction of the patchy satellite data into one meaningful data. Orbit information and operational plan of each satellite will be made available to the amateur radio community in the world. Software to decode the satellite data will be also made available.

The respective amateur ground stations that can successfully decode the telemetry data, music and the Earth images, shall receive a QSL card from the BIRDS team. The data reconstructed by the effort of the amateur ground station network will be made public to share the sense of satisfaction and achievement.

BIRDS CubeSat NationsA particularly interesting mission of BIRDS project is the SNG mission that exchanges music via a digi-singer. It is an outreach-oriented mission. First, music in MIDI format is uploaded from ground. Then the MIDI file is processed on-board using a vocal synthesizer. Finally, the processed music is sent back to Earth using UHF antenna as voice FM data.

During organized events on space utilization with schools or general public, music could be heard using a common hand-held receiver and hand-made Yagi antenna positioned to track the satellite at each given pass over the region. This has a tremendous effect on awareness of radio communication among school children and general public, especially in the countries participating in the BIRDS project, Japan, Ghana, Mongolia, Nigeria and Bangladesh.

Proposing to use CW, 1k2 AFSK FM, audio FM and 9k6 GMSK downlinks. Planning a JAXA sponsored deployment from the ISS during 2017.

The ARRL reports Slow-scan television (SSTV) transmissions will be made from the International Space Station (ISS) on August 15-16, 2016.

The MAI-75 Experiment will transmit SSTV images on 145.800 MHz FM over the course of a few orbits as the space station passes over Moscow. Operators in Europe and South America will have the best chances to receive images. Operators along the US East Coast may have one chance on August 16.

The story behind $50SAT, a new approach to amateur satellite design which became the world’s smallest operational satellite, built for £125 in a garden shed.

On Saturday, August 6, Stuart Robinson GW7HPW gave a presentation on the amateur radio satellite $50SAT to the Electromagnetic Field event EMF 2016 in Guildford.

Talk Description: If you are building an Amateur satellite the simple choice would be to assemble a device with all the latest satisfyingly advanced and complex tech. The $50SAT team made a decision to go against convention and produce a design with the minimum of components.

$50SAT was the first of a new class of satellite pioneered by Professor Bob Twiggs KE6QMD; the PocketQubes, designed to be small and light so they would be cheap to launch. $50SAT was launched in November 2013 using a Dnepr rocket from Dombarovsky Air Base in Russia and remained working in orbit for 20 months, the team had only expected it to last for a month at best.

Dave Rowntree 2E0DVR, drummer in the rock-band Blur, gave a presentation on amateur radio satellites at the Electromagnetic Field event EMF 2016 in Guildford.

Talk description: There are about a dozen communications satellites orbiting the earth that were designed and built by teams of amateur enthusiasts. Dave talks about what they are, how they got there, and how you can build simple equipment to listen to their transmissions.

Due to the massive interest in amateur satellite operating generated by both Dave’s talk and the recent TX Factor Show video the book Getting Started with Amateur Satellites 2016 has completely sold old. A new print run is underway and the book should be back in stock in the AMSAT-UK online shop on August 14.
