COMPASS 2 will become the second student satellite from the FH Aachen University of Applied Sciences, Germany.

Like the first satellite project COMPASS 1, COMPASS 2 was developed based on the CubeSat standard as a Triple-CubeSat, which means a total weight of 3 kg and dimensions of 100x100x340.5mm and will be deployed at an altitude of 500km and an inclination of 97.4622┬░.

The students of the FH Aachen University of Applied Sciences developed the bus system with the necessary subsystems for power generation, power distribution, data handling, communication and data / power interface for the payload.

There are two experiment payloads onbord our satellite: a so called DragSail and Thin Film Solar Cells.

Currently students of the FH Aachen are preparing the flight operations phase of the mission. Our launch is currently planned for late June 2017.

Dear amateur radio operators,

the COMPASS-2 satellite Flight Operations team is currently looking for partner groundstations located in France, Spain, Italy and north-western Africa.

Currently we have some trouble receiving a proper signal from our satellite and we hope you could assist us getting a good signal by giving us access to your groundstation.

Our current idea is to extend our time we have acquisition of signal with our satellite by using your groundstation in addition to ours.

If you are interested in helping us and be part of a real space mission then contact us!

Your groundstation should be able to send signals at 145.885MHz and receive signals at 437.300MHz to communicate with our satellite.

Kind regards,
The COMPASS-2 Flight Operations team

Liebe Raumfahrtbegeisterte,

das COMPASS 2 Team des Fachbereich 6 Luft- und Raumfahrttechnik der FH Aachen l├Ądt Sie herzlich zum Launch Event des von Studierenden der FH Aachen entwickelten und gebauten Satelliten COMPASS 2 ein. Dort werden Sie die M├Âglichkeit bekommen Live beim Start dabei zu sein und im Anschluss den ersten ├ťberflug ├╝ber unsere eigene Bodenstation in Aachen mitzuerleben, bei dem hoffentlich das erste Datenpaket vom Satelliten empfangen wird!

Das Studierendenprojekt COMPASS befasst sich mit der Entwicklung, dem Bau und dem Betrieb von Kleinsatelliten nach dem CubeSat-Standard. Aktuell arbeiten noch ca. 10 Studierende am Missionsbetrieb des COMPASS-2 Satelliten.
Bei COMPASS-2 handelt es sich um einen 3-fach Cube, dessen zentrale Einheit alle Subsysteme eines Satelliten wie z.B. Struktur, Lageregelung, Energieversorgung, Thermalhaushalt oder Kommunikationsmodul (mit Ausnahme der Nutzlast) enth├Ąlt. Diese Subsysteme wurden alle von Studierenden der FH Aachen mit Unterst├╝tzung durch die RWTH im Kommunikationsbereich gebaut und entwickelt.
In den beiden ├Ąu├čeren CubeSat-W├╝rfeln wurden wissenschaftliche Experiment-nutzlasten eingebaut. In Kooperation mit dem FHprofUnt-Projekt "DragSail - CubeSat" wurden f├╝r eine der beiden Nutzlast-W├╝rfel ein entfaltbares Widerstandssegel entwickelt, welches den Wiedereintritt des Satelliten am Ende seiner Lebenszeit beschleunigt, so dass er fr├╝her in der Erdatmosph├Ąre vergl├╝ht. Dadurch wird Weltraumm├╝ll vermieden und die wertvolle Infrastruktur des niedrigen Erdorbits gesch├╝tzt. In dem anderen Nutzlast-W├╝rfel sind innovative, entrollbare D├╝nnschicht-Solarzellen untergebracht, die im Orbit entfaltet und unter Weltraumbedingungen getestet werden.
Hierbei konnte das COMPASS-2 Team sein "Know-How" f├╝r eine erfolgreiche Entwicklung einbringen. Zus├Ątzlich wurde das Ziel COMPASS-2 im Orbit zu verifizieren durch eine Partnerschaft mit dem QB50-EU-Programm und dessen Startoption realisiert.

Als Gespr├Ąchspartner stehen Ihnen zur Verf├╝gung:
Prof. Dr.-Ing. Peter Dahmann, Dekan des Fachbereich 6 Luft- und Raumfahrttechnik
Prof Dr.-Ing. Bernd Dachwald, Raumfahrtprofessor Fachbereich 6 Luft- und Raumfahrttechnik und betreuender Professor des Projekts COMPASS-2
Dipl.-Ing. Engelbert Plescher, Projekt Manager COMPASS-2
Dipl.-Ing. Sacha Tholl, Groundstation Manager und Flight Director COMPASS-2
Jannik Schatz, aktueller studentischer Projektleiter COMPASS-2
Sowie andere Teammitglieder des Flight Operations Team von COMPASS-2

Die Veranstaltung findet am Freitag, den 23. Juni 2017 statt!

Den Start unseres Satelliten k├Ânnen Sie in der Hohenstaufenallee 6, 52064 Aachen, Raum 01103 (1. OG) um 05:59 Uhr verfolgen.

Die Hohenstaufenallee ist zu diesem Zwecke ab 05:30 Uhr f├╝r alle Interessierten ge├Âffnet!
Ab 09:30 Uhr wird es im gleichen Raum Vortr├Ąge ├╝ber den Satelliten, die Tr├Ągerrakete und das Team geben!

Ebenso wird im gleichen Raum ab 10:35 Uhr der erste ├ťberflug ├╝ber unsere Bodenstation LIVE ├╝bertragen!

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 Einf├╝hrung in die Denkweise eines Satelliten Flight Controller.

Besonderen Dank an all die ESA Mitarbeiter die uns offen willkommen gehei├čen haben uns unsere vielen Fragen beantwortet haben! ­čÖé

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 didnÔÇÖt 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 PashkovÔÇÖs 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 DmitryÔÇÖs 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 controlÔÇÖs ground track diagram, the Soyuz MS-03 must have been already coasting over đÂđ░đ╗đ│ĐőđĚĐéđ░đ╗/ 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).

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 erh├Âhen wir das Oberfl├Ąche-zu-Masse-Verh├Ąltnis sodass der Widerstand durch die Restatmosph├Ąre k├╝nstlich erh├Âht wird. Damit beschleunigen wir die Verringerung des Orbits. Wir wollen herausfinden, ob dies ein gangbarer Weg ist k├╝nftig Space Debris zu reduzieren.
