COMPASS-2 will become the second student satellite from the FH Aachen, Germany.

Like the first satellite project COMPASS-1, COMPASS-2 will be developed based on the CubeSat standard. It will be developed as a Triple-CubeSat, which means a total weight of 3 kg and dimensions of 100x100x340.5mm.

The students of the FH-Aachen will develop the BUS system with the necessary subsystems for power generation, power distribution, data handling, communication and data / power interface for the payload.

There will be two experimental boxes placed around the BUS-Cube that can easily be replaced using a standardized connection system that will be developed by the students of the FH-Aachen.

A few days ago the COMPASS 2 operations team visited the ESOC - European Space Operations Centre. There ESA - European Space Agency employees showed us how they control their satellites and gave us an introduction on how to be a spacecraft operator. It was a very intense day and we learnt a lot!

Thanks to all the ESA people there who openly welcomed us and showed us around!

Vor einigen Tagen besuchte das COMPASS 2 ops Team das ESOC in Darmstadt. Dort zeigten uns Mitarbeiter der ESA wie diese ihre Satelliten steuern und kontrollieren und gaben uns eine Einführung in die Denkweise eines Satelliten Flight Controller.

Besonderen Dank an all die ESA Mitarbeiter die uns offen willkommen geheißen haben uns unsere vielen Fragen beantwortet haben! 🙂

Am Samstag den 4. Februar stellte sich das COMPASS 2 Team neben vielen anderen studentischen Projekten der FH Aachen am Hochschulinformationstag (HIT) in der Eupener Straße 70 der FH Aachen - University of Applied Sciences vor!
Neben regem Interesse vieler künftiger Studenten an dem Studiengang der Luft- und Raumfahrttechnik und dem Leben als Student in Aachen gab es auch allseits großes Staunen, dass Studenten an der FH Aachen bereits die Möglichkeit haben an Projekten wie dem COMPASS 2 Projekt mitarbeiten zu können.

Auch besuchte uns unser Dekan des Fachbereichs 6 Luft- und Raumfahrttechnik Prof. Dahmann und stellte mit Stolz seinen Professoren-Kollegen unser Projekt vor.

Alles in Allem ein gelungener und erfolgreicher Tag! 🙂

Compass Ground Station Team was able to hear the Soyuz MS-03:

In order to practice some ground station operation skills, we decided to track the Soyuz MS-03 (Call sign: Kazbek) on it's way to the rendezvous with the ISS. For that purpose we tried out two different web based software defined amateur radio stations (websdr) The first one is located in Czech republic (Sdr air band station Hradec Kralove) and the other one is located at Ruzaevka Energeticheskaya in Russia (locator: LO24LA; WGS-84 coordinates: 54.026157894001°N, 44.958611395001°E) and is maintained by the amateur radio operator R4UAB (Dmitry Pashkov). Whereas the Czech station received the audio signals with a signal strength equal or less than S7 at noticeably high QRN, the same audio signals were received on the Russian websdr station with signal strengths between S7 and S9 and very low QRM and QRN, as this station is dedicated to satellite downlink communications. So we decided to go on with the later mentioned, using VHF base frequency 121750kHz for the first and second day. Although we had captured quite some good quality audio records we unfortunately didn’t log the position of the Soyuz MS-03. The best recording obtained can be retrieved here: https://www.youtube.com/watch?v=DiltGNBS8A0
For the third day, we decided to do better and started listening on Dmitry Pashkov’s websdr during the last pass before the docking, using VHF 143625kHz base frequency and in parallel, following the sub- satellite point of the Soyuz MS-03 at that moment using the ground track live feed which is publically available by the Russian mission control centre. At 20:41:40 UTC we were able to receive a somewhat audible voice signal from the Soyuz MS-03 with a frequency Doppler shift of +7.59kHz with respect to the base frequency, as it was coasting towards the websdr station. According to the ground track live feed, we estimate that the sub satellite point of the chaser must have been located not far away from the island Rodos near Greece (WGS-84 coordinates: 36.15°N; 28.25°E). At that moment, the Soyuz MS-03 must have been some (2404 ± 23)km away from Dmitry’s station. Using some simple arithmetic calculations, we came to the conclusion that the chaser roughly must have been seen from the station at an azimuth of (219.8 ± 0.2)° clockwise from the north and an elevation of (12.17 ± 2.3) °, if an altitude of (412.15 ± 8.15 )km above mean sea level (MSL) can be assumed.

The last audio signal we were able to capture has been recorded at 20:50:00 UTC with a Doppler shift of -4.35kHz with respect to the base frequency. According to the Russian mission control’s ground track diagram, the Soyuz MS-03 must have been already coasting over жалгызтал/ Kazakhstan (WGS-84 coordinates: 49.950000°N; 67.380000°E), some (1647.62 ± 24)km away from the web-sdr station. We estimate that the azimuth with respect to the station must have been about (97.25 ± 0.2)° clockwise from the north at an estimated elevation angle of (18.21 ± 3.72)° , if we still assume an altitude of (412.15 ± 8.15 )km above MSL). The Recording of the pass can be retrieved here: https://www.youtube.com/watch?v=twn4NHAAj54&feature=youtu.be

This is our DragSail, our main experiment:
We are planning to deploy this DragSail to increase the area-to-mass-ratio so that the drag is artificially increased and so the orbital decay as well. We want to see with that experiment if this is a possible way to reduce space debris by reducing the orbit faster.

Dies ist unser DragSail, unser Hauptexperiment:
Wir planen dieses im Orbit auszuwerfen. Damit erhöhen wir das Oberfläche-zu-Masse-Verhältnis sodass der Widerstand durch die Restatmosphäre künstlich erhöht wird. Damit beschleunigen wir die Verringerung des Orbits. Wir wollen herausfinden, ob dies ein gangbarer Weg ist künftig Space Debris zu reduzieren.

Hey guys,
I would like to provide you with a short update where we are right now:

We are almost finished with working on the satellite. Some last minute updates on our flight software still have to be made and some very last parts have to be installed. However 99% of the satellite is finished and on the 7th of Decemeber we are going to ship our satellite to our launch provider. After that day no more adjustments to our satellite is possible.
Currently the launch is scheduled for April 2017. We are planning to launch on an Indian PSLV rocket.

So we have started to train ourselves to become radio operator to send signals to our satellite via amateur radio, ground controller to operate our ground station and flight controller to control our satellite with our groundstation.

Hallo Leute,
Heute möchte ich euch mit einem kleinen Update versorgen wo wir aktuell stehen mit unserem Satelltien:

Wir sind mit der Entwicklung unseres Satelliten nahezu fertig. Ein paar kleine Software Anpassungen hier und da müssen noch gemacht werden und zu guter Letzt noch ein paar allerletzte Teile montiert werden. Allerdings kann man sagen, dass unser Satellit zu 99% fertig ist. Daher planen wir diesen am 7. Dezember zu unsererm Startanbieter zu schicken. Nach diesem Tag können wir keine weiteren Anpassungen mehr an unserem Satelliten vornehmen.
Aktuell ist unser Start für den April 2017 angesetzt. Der Start soll auf einer indischen PSLV Rakete erfolgen.

Wir haben bereits angefangen uns selbst als Amateurfunker auszubilden. Dies ist notwendig, um unseren Satelltien anzufunken und Kommandos hochzuschicken. Außerdem haben wir begonnen uns selbst mit der Bodenstation und den Flight Control Software vertraut zu machen die von uns selbst geschrieben wurde. Alles in Vorbereitung dafür, dass wir bereit sind sowie der Satelltit gestartet ist.
