RSGB President Dave Wilson M0OBW Presents Louis Varney G5RV Cup to Paul Robinson 2E1EUB

Paul Robinson 2E1EUB will be guest speaker at the Telford and District Amateur Radio Society (TDARS) on Wednesday, March 21, where he will give a talk about amateur radio satellites.

In 2011 Paul was awarded the prestigeous Louis Varney Cup for Advances in Space Communication, which was presented to him at the Telford Hamfest.

Over the years Paul has worked promoting and encouraging the use of amateur radio satellites and perfecting the art of a portable ground station.

Amateur radio satellite communications can be acheived using very simple equipment. You don’t need high power or massive antennas.  If you want to find out more about this fascinating part of the hobby make sure you get to Paul’s talk.

The meeting starts at 7 pm on Wednesday, March 21 at Little Wenlock Village Hall, Malthouse Bank, Little Wenlock, Telford, TF6 5BG.

At the conference, ISIS has managed to write a last-minute resolution which was submitted by a group of countries, led by The Netherlands. The aim of this resolution is to propose an agenda item for the next WRC (2015), which proposes to conduct studies to identify the spectrum needs of nano-and picosatellites, and furthermore to study the associated regulatory constraints. After the discussions at the WRC, the resolution got partially accepted by the conference (only the regulatory aspects will be studied), and not for the WRC-2015 but for the WRC after that, which will be in 2018. The provisional final acts of WRC2012 has been published, I quote:

“2.2 to consider the appropriate regulatory procedures for notifying satellite networks needed to facilitate the deployment and operation of nano- and picosatellites, in accordance with Resolution COM6/10 (WRC-12); ”

TIES users can download the provisional final acts at http://www.itu.int/md/R12-WRC12-R-0001/en

This is very good news, and could mean that the ITU notification process for nano and picosatellites can become greatly simplified in the future. We first of all would like to thank all the supporting administrations for their support and would like to invite the community to, through their administrations, participate in the studies, so that the outcome will be as much as possible line with the needs of the community.

We will continue to work on this subject and keep you updated through these lists and at the various small / nano / picosatellite conferences and workshops.

kind regards,

Lift off of Vega - Image Credit ESA

The first Vega, flight VV01, lifted off at 1000 UT Monday, February 13 from the ESA Spaceport at Kourou in the Caribbean carrying eight student built amateur radio satellites and the LARES Laser Relativity Satellite into orbit.

LARES was put into a 1435 by 1452 km 69.5 degree inclination orbit, while the orbit of the amateur radio satellites is 310 by 1441 km.

At 1153 UT Drew Glasbrenner KO4MA reported hearing signals from the satellites as they went past Florida. Signals were first heard in the United Kingdom at around 1207 UT.

In Germany Mike Repprecht DK3WN copied the satellites at an elevation of just 3 degress at 1209 UT, see http://www.dk3wn.info/p/?cat=83

A recording of PW-Sat made by Wouter Weggelaar PA3WEG at 1207 UT can be heard at http://www.pa3weg.nl/pa3weg/recordings/PW-SAT%20recording%20PA3WEG%2013-02-2012_1207UTC.mp3

In the Czech Republic Mirek Kasal OK2AQ received strong signals from Masat-1 http://www.urel.feec.vutbr.cz/esl/files/Othact/masat1_rev5.wav

Nittin Muttin VU3TYG received PW-Sat at 1246 UT as it travelled over India, his recording is at http://vu3tyg.addr.com/pwsat/pw_sat-%20Feb%2013th.mp3

In Sudan Nader ST2NH received signals from AlmaSat-1 and Masat-1.

KO4MA Screenshot of Vega CubeSats

As of Monday evening signals had been reported from AlmaSat-1, Goliat, Masat-1, PW-Sat, UniCubeSat and XaTcobeo.

All the Vega amateur radio satellite project teams used the IARU amateur satellite frequency coordination panel service. A benefit of IARU coordination was that all the different UHF satellite signals could be simultaneously captured within the typical 192 kHz bandwidth of a modern Software Defined Radio (SDR).

PW-Sat is the only satellite with a downlink in the 145 MHz band. Its 1200bps BPSK signal on 145.900 MHz is receiveable with an SSB radio and an omni-directional antenna.

When PW-Sat has finished its primary scientific mission it will be reconfigured as a 435/145 MHz FM to DSB transponder for general amateur radio communications. The FM to Double Sideband transponder was first pioneered by amateurs on the satellite AO-16.

PW-Sat carries a deployable drag augmentation device known as the tail. The main objective of this experiment is to test the concept of using atmospheric drag to deorbit the satellite. It is hoped to be able to remove the satellite from orbit at a predicted time, about one year after launch.

The other amateur radio satellites have downlinks in 437 MHz. A small 430 MHz  band Yagi antenna may be used to receive the signals. They are expected to have a lifetime of 3-4 years depending on the atmospheric drag which is higher at sunspot maximum.

Watch the launch of Vega VV01

The Masat-1 satellite team have made available software to decode their 437.345 MHz telemetry data via a PC sound card. The software can be downloaded from http://cubesat.bme.hu/en/foldi-allomas/kliens-szoftver/

This video shows the eliptical 310 by 1441 km orbit of the satellites.

The prelimary TLEs, used by tracking software to predict the orbits, were generated by a team lead by Paolo Tortora at the University of Bologna in Italy. They proved to be accurate with the satellites appearing at the expected time.

Student amateur radio satellite downlink frequencies:
(Worst case Doppler shift during pass +/-9 kHz at 437 MHz and +/- 3 kHz at 145 MHz)
+ AlmaSat-1   437.465 MHz 1200 bps FSK, 2407.850 MHz
+ E-St@r        437.445 MHz 1200 bps AFSK
+ Goliat          437.485 MHz 1200 bpx AFSK
+ Masat-1      437.345 MHz 625/1250 bps GFSK, CW
+ PW-Sat       145.900 MHz 1200 bps BPSK AX25, CW
+ Robusta      437.325 MHz 1200 bps FM telemetry – one data burst of 20 secs every 1 min (may be 437.340 MHz)
+ UniCubeSat 437.305 MHz 9600 bps FSK
+ XaTcobeo     437.365 MHz FFSK with AX.25

AMSAT-UK FUNcube Mission Patch

In just 16 months the AMSAT-UK FUNcube Yahoo Group has exceeded a membership of 3000.

The group was created by Rob Styles M0TFO at the end of October 2010 to provide support for the AMSAT-UK FUNcube satellite and the FUNcube Dongle VHF/UHF Software Defined Radio.

The FUNcube satellite project is an educational CubeSat project with the goal of enthusing and educating young people about radio, space, physics and electronics. It will support the educational Science, Technology, Engineering and Maths (STEM) initiatives and provide an additional resource for the RSGB GB4FUN Radio Communications Demonstration Module. The target audience is school pupils in the 8-18 age range.

As well as providing a strong 145 MHz telemetry beacon for the pupils to receive FUNcube will also have a 435/145 MHz linear transponder for Amateur Radio SSB/CW use.

The FUNcube Dongle VHF/UHF SDR was originally developed for educational outreach as part of the ground segment for the FUNcube satellite. However, it was realised it can be used for many other applications as well, so AMSAT-UK developed a Pro version which has a frequency range of 64-1700 MHz.

Similar to a USB TV Dongle, the FCD simply fits into a computer USB port and can be used with freely available Software Defined Radio software. The FCD is all-mode which this means that as well as data, it will also receive many other signals including AM, FM, SSB and CW. It can even receive weather satellite pictures.

You can join the FUNcube Yahoo Group at http://uk.groups.yahoo.com/group/FUNcube/

More information on the FUNcube satellite project is at http://FUNcube.org.uk/overview/

These satellites called “CubeSats”, completely functional, are built by universities for an educational purpose. All 50 CubeSats will be launched out of Murmansk, situated in the Northern Russia, into a circular orbit at 320 km altitude, inclination 79° around the Earth. Due to atmospheric drag, the orbits will decay and progressively lower layers of the thermosphere / ionosphere will be then explored. A network of standard satellites for in-situ measurements can only be realized by using very low-cost satellites, and CubeSats are the only realistic option.

This project includes universities in 30 European countries and universities in Argentina, Australia, Brazil, Canada, Chile, China, Egypt, Israel, Japan, Peru, Russia, South Africa, South Korea, Taiwan, Thailand, Turkey, Ukraine, USA and Vietnam. For many of these countries, CubeSats will be their first satellite in orbit and a matter of national prestige.

The von Karman institute for Fluid Dynamics (VKI) is the lead institute of this consortium and manages this international project which involves over 500 researchers from 50 countries. Jean Muylaert, Director of the Institute and responsible for the project, stresses that it will be the first time that a dedicated CubeSat space mission will be performed for unique atmospheric science and also to demonstrate new in-orbit qualification methods.

Mike DK3WN has developed a simple solution to this perenial problem by using an SDR-IQ receiver and a bit of software.

In the case of Masat-1 he chose a high elevation pass (89 deg) where the doppler shift should be significant and recorded the complete pass with his SDR-IQ without doppler correction. With some software he simulated the entire pass with different TLE’s.

He then chose the TLE that best matched the doppler shift of the audio signal.
