Building a Distributed Satellite Ground Station Network

There was a presentation on building a distributed satellite ground station network at the Chaos Communication Congress held December 27-30 and the video is now available.

The AMSAT-UK FUNcube Dongle VHF/UHF Software Defined Radio gets a brief mention at 39:26 into the video.

The video kicks off with an appearance by Nick Farr then the presentation by Gregor Jehle (Hadez), Armin Bauer and Andreas Hornig gets underway.

Students working on the Aalto-1 CubeSat have released a 4 minute video showing a visualization of the launch and deployment of the satellite.

Aalto-1 is a student satellite project of Aalto University, Finland. When launched, it will be Finland’s first satellite.

It is planned to operate at VHF-UHF and there will also be an S-band transmitter. Up to 8 watts of power will be available from the Solar panels.

The main payload of the satellite is a novel tiny Fabry-Perot imaging spectrometer, developed by VTT, Finland. The primary scientific goal of the mission is to demonstrate the feasibility of MEMS Fabry-Perot spectrometers for space applications. This miniature technology can be used in nanosatellites for large a variety of remote sensing applications in the future.

High spectral resolution images can be used for water quality monitoring and land use classification.

Vega rocket ready for first flight

Vega rocket ready for first flight

19 January 2012
Final checkout of Europe’s new Vega launcher was completed last Friday, marking another milestone towards its maiden flight from Europe’s Spaceport in Kourou, French Guiana.

The first Vega launch campaign began in November with the installation of the P80 first stage on the launch pad. The two solid-propellant second and third stages were added to the vehicle, followed by the AVUM – Attitude & Vernier Upper Module – liquid-propellant fourth stage.

All four stages have undergone final acceptance, including the testing of the avionics, guidance, telemetry, propulsion, separation pyrotechnics and safety systems.These steps culminated on 13 January with Vega’s ‘synthesis control checks’, where all systems were put into launch mode for the vehicle’s final acceptance. This included pressurising the AVUM propulsion systems that actuate the thruster valves.

The rocket’s elements were switched on from the control bench to simulate the launch countdown. The onboard software then took over and simulated the different stages of a flight. The interfaces between the vehicle and the control bench were also tested.

The test review confirmed that everything ran as expected and that the launcher is ready for flight.

What’s next?

The ‘upper composite’ – the fairing and payload – will be integrated, followed by final checkout of the fully assembled launcher and the countdown rehearsal.

The first launch, VV01, is targeted for 9 February. It will carry nine satellites into orbit: the Italian space agency’s LARES and ALMASat-1, together with seven CubeSats from European universities.

This mission aims to qualify the Vega launch system, including the vehicle, its launch infrastructure and operations, from the launch campaign to payload separation and disposal of the upper module.

A flexible system

Vega is designed to cope with a wide range of missions and payload configurations in order to respond to different market opportunities and provide great flexibility.

In particular, it offers configurations able to handle payloads ranging from a single satellite up to one main satellite plus six microsatellites.

Vega is compatible with payload masses ranging from 300 kg to 2500 kg, depending on the type and altitude of the orbit required by the customers. The benchmark is for 1500 kg into a 700 km-altitude polar orbit.

More information on Vega and updates are now available on the new launch website here.

QRP APRS Packet Radio to the ISS

International Space Station

Doug Cook KD5PDN’s article about contacting the International Space Station with a few watts and a shoestring budget antenna is now available.

The article “QRP to the ISS” appeared in the February, 2012 issue of QST magazine and, with permission from the ARRL, can be downloaded from Clint Bradford K6LCS’s website.

Doug walks the reader through building a simple tape measure beam, and how to successfully work the ISS with it and a handheld radio.

Read the article at http://www.work-sat.com/Work-Sat/Misc_files/QRP-ISS.pdf

A video by author Doug Cook KD5PDN shows the tape rule antenna and how to set up a Yaesu VX-8R for ISS APRS packet data sending and receiving and other aspects to make a digital contact with the International Space Station. You can also learn how to interpret the audio prompts when packet data is being received.

Student D-STAR Satellite to Launch in 2012

Students at workStudents at the University of Liege are hoping their D-Star GMSK satellite OUFTI-1 will be launched towards the end of this year.

An update on the satellite is published in the January 2012  issue of the OUFTI-1 newsletter at
http://www.leodium.ulg.ac.be/cmsms/uploads/OUFTI-1%20Newsletter%204.pdf

The satellite will have uplinks in the 145 MHz band and downlinks on 435.015 and 435.045 MHz.

Sounds From Space website looking for additional sounds

 Matthias, DD1US, would like to draw your attention to a collection of audio recordings, the ‘Sounds From Space‘ collection on his website at http://www.dd1us.de. This features a collection which has also a section dedicated to recordings of amateur radio satellite signals.

Please have a look at it. The idea is to give older radio amateurs the chance, to listen to signals of satellites which are already gone and the might have worked in the past, and to younger people interested in ham radio, to get them more excited in satellite communication.

In spite of the fact that the collection now has close to 1000 recordings he is still missing recordings from some amateur radio satellites.
If anyone of you would be willing to contribute recordings to these satellite he would highly appreciate it. He has and always will give full credit to the source of the recordings. Please have a look in your older tapes and recordings!
