KN-SAT1 students at ST2UOK Khartoum

Students at the University of Khartoum, Sudan have been eagerly listening for the new amateur radio satellites deployed by the Vega launcher on Monday, Feb 13.

The students are undertaking a CubeSat project KN-SAT1. As part of the project they recently completed the installation of a satellite groundstation at ST2UOK. This was used to track and receive telemetry data from the Vega satellites.

KN-SAT1 is the first CubeSat to be built in Sudan and an aim is to promote space engineering and space science education at other Sudanese educational institutes.

FUNcube group exceeds 3000 members

AMSAT-UK FUNcube Mission Patch Rev4 20100609

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.

Solving the TLE lottery

TLEsWhen amateur radio satellites are initially deployed Two Line Elements (TLE) Keplerian orbital data sets for tracking the satellites are released by NORAD. Unfortunately they are only given object identifiers of A, B, C, D etc not satellite names. Some of the debris from the launch and deployment may also be given alphabetic identifiers. The problem is working out which of the 10 or more objects is the satellite you want to listen to.

Mike DK3WN has developed a simple solution to this perennial 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.

Open Mission Control Software for Satellite & Balloon Projects

Open Mission Control

Open Mission Control

Open Mission Control is open source, open access software for monitoring and controlling small spacecraft or balloon projects.

The software is designed to provide an application and framework that can be adapted quickly and easily to support a variety of spacecraft including CubeSats, myPocketQubs and NanoLab experiments, and sounding rocket and high altitude balloon experiments.

The team include students, space professionals, educators and enthusiasts from around the world, all working together to build a great mission control application for small spacecraft projects.

The Open Mission Control framework consists of the application and graphical user interface which contain the basic structure of the program, and the Open Mission Control toolbox, which provides a number of ready to use functions typically required for mission control applications.

The Open Mission Control application and graphical user interface can be adapted to a project quickly and easily, by populating them with elements from the Open Mission Control toolbox and other standard library elements. This approach allows also users with limited programming experience to create sophisticated mission control software by building on a solid basic implementation.

Designed to work with any spacecraft project, the first flight mission that is expected to use Open Mission Control is myPocketQub442. Developed by UK Students for the Exploration and Development of Space (UKSEDS) myPocketQub442 was selected to fly as a pocket spacecraft attached to UKube-1, the first United Kingdom Space Agency CubeSat. It is expected to be the first mission controlled by Open Mission Control and to demonstrate and verify various use cases:

+ The first use case is for professional monitoring, command and control of a real spacecraft.

+ The second use case involves schools and universities using Open Mission Control to upload their virtual payloads for their OpenSpace365 projects, monitor their experiments as they run and download the data for analysis.

+ The third use case involves the use of Open Mission Control as monitoring software for the various scientific and engineering sub-payloads that will fly on myPocketQub442. The students conducting these experiments will use Open Mission Control to access and store the data from these payload experiments for analysis and research.

+ The fourth use case is communication with engineering models of the real spacecraft which will be made available on the Internet. These engineering models are duplicates of the flight hardware and allow Open Mission Control to command and monitor them and their sub-payloads in real time and to simulate different critical mission phases under real conditions.

The launch of eight student amateur radio satellites from the space center at Kourou in the Caribbean will be broadcast live on the Internet.

The launch should take place between 1000-1300 UT on Monday, February 13 and you’ll be able to watch it at http://www.videocorner.tv/

The student teams have requested reception reports. During the Launch and Early Operations Phase (LEOP) Monday, listeners are encouraged to gather at the IRC “cubesat” channel to exchange all the latest available information. Simply point your browser to http://webchat.freenode.net/ and join the #cubesat channel. In the Nickname: field enter “name_callsign” and in the Channels: field enter #cubesat

Preliminary Vega TLE’s for launch at 1000, 1100 or 1200 UT here

Assuming a 1000 UT launch the satellites should deploy their antennas and start transmitting at about 1140 UT. It looks like the first to get reception will be Central America followed quickly by a pass up the East coast of North America. The first pass for the United Kingdom should be a horizon skimmer across the NW at around 1207 UT.
