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.

Late Night tracking at the Compass Lab in Aachen. Got some good results from TIGRISAT and VZLUSAT.

During the tracking of COMPASS-2, FOX-1D was really close by and we were able to listen to the voice transmissions over its transponder. This made us so curious that we would like to join in soon!

Tonight we made our first tracking session after the Maintenance of our Ground station. Hamlib is now living in a virtualbox on Ubuntu 17 and works flawlessly with the NITEC rotor controller. We acquired signals from NOAA-19, NOAA-15, Tigrisat, NSIGHT-1, Lituanicasat-2 and Grifex.

Operators: Hannah Walther Sacha Joseph Tholl und Sunny Singh 🚀🛰️

From Thursday till Sunday Professor Nohmi from the Kagawa University of Japan visited the COMPASS project team and every evening we did some operations for their STARS-C cubesat.

We successfully tracked their satellite at total of 10 passes over Aachen and sent some commands to their satellite on their behalf.

For that our groundstations at the Eupener Straße as well as our groundstation at the Hohenstaufenallee were in action!

We received CW signals at 437.245MHz base frequency. The analyses is still ongoing but first checks are showing quite promising data acquired! We are really happy that we were to be able to help our friends from Japan and hope that in the future we can help them again!

Soyuz MS-07 voice capture during pass over our ground station DL0FHA

Autors: Sacha Joseph Tholl, Ian Benecken
Operators: Ian Beneken, Kübra Yilmaz
Translator: Alina Schneider

Very fortunate, the compass team was generously rewarded by Santa Claus on December, the 18th between 13:22:47 and 13:25:66 utc. The Soyuz-MS 07 had left Baikonur launch pad LC-1 one day earlier, carrying cosmonaut commander Anton Shkaplerov, the Japanese astronaut Norishige Kanai and the American astronaut Scott Tingle to the International Space Station (ISS). This time, the Soyuz had to take the 2 day rendezvous approach (34 Orbits) to the ISS instead of the usual six hours (4 Orbits) travel, due to certain orbital parameters of the ISS. This was indeed our fortune. In-fact, we were able to receive five consecutive voice transmissions performed by astronaut commander Anton Shkaplerov aboard the Soyuz-MS 07 as he was most probably being in communication with TSuP (Mission Control) Moscow.

Because the Soyuz rapidly changes its orbit due to the high number of orbit adjustment burns called DV (delta velocity) burns, the orbital parameters change quite rapidly. In order to check the validity of the TLE retrieved from Celestrack, we counter checked the current position with the live tracking interface provided by TSuP publically from the website before we pointed our antennas toward the Soyuz. Here you can find the url for the http://193.233.61.44/miopApp/miopClient1?service=isstd
As can be seen from the table above, the first voice signal from Soyuz MS-07 came through our antennas at an elevation angle of 25.6° at 13:23:01 utc. At that time, with a range of 552 km away from our ground station, the Soyuz was coasting over the village Wetterzeube, some 36 kilometers away from Jena in Germany.

Then as the capsule passed over Mittweida / Germany, we received the 2nd voice signal. One Minute later, we captured the 3rd voice signal when the Soyuz already was over Jankowice in Poland. The 4th voice contact we received as the capsule was already coasting over Maškovce in Slovakia, some 50 kilometers away from the nearest Ukrainian border. The last voice transmission we got from Soyuz, it was coasting over the town Petryliv, which is located in the Ivano-Frankivs'ka region of Ukraine, some 1444 kilometers away from DL0FHA ground station.

A shortened audio recording of the captured voice transmission during the pass over DL0FHA can be retrieved using the following link:

This is our most extreme recent NOAA image. It shows mostly the atlantic ocean. But one can see a glimpse of Iceland and Greenland at the top and a small island of the Azores "Ilha das Flores" at the bottom.

The picture was received as the NOAA 15 Satellite passed with only a maximum of 5 deg elevation above horizon.
Our antenna is capable of receiving this signals even lower than 1 deg. Only because of the sensitive antenna and the amazing signal strength of the NOAA satellites it is possible to receive pictures so far from our groundstation, located in the very west of germany.

Last Thursday we analyzed what we received last Saturday when we had your mulit-groundstation tracking session. Our goal was it to check if the TLE data of COMPASS-2 and VENTA-1 were switched. So we pointed our antennas at the Venta-1 TLE. However we were not able to receive any data from COMPASS-2 nor VENTA-1, but we received data from Robusta-1B and VZLUsat-1.

Here you can see a (German) video of all data we received on that day, our flight loop and an analysis from our flight director Sacha Tholl at the end:

Letzten Donnerstag haben wir als COMPASS Bodenstationsteam den Multi-Groundstation Überflug analysiert den wir vorherigen Samstag durchgeführt haben. Das Ziel dieser Aktion war es zu überprüfen ob die TLEs von COMPASS-2 und VENTA-1 vertauscht sind. Dafür haben wir auf die TLE von Venta-1 gehalten Jedoch haben wir weder von COMPASS-2 noch von VENTA-1 Telemetriedaten empfangen können. Jedoch von Robusta-1B sowie VZLUsat-1.

Hier könnt ihr ein Video unseres Überfluges von letzten Samstag sehen mit unserem jeweiligen Flight Loop. Am ende des Videos gibt unser Flight Director Sacha Tholl noch eine abschließende Analyse:

Last Saturday we tracked Robusta-1B and Venta-1 with mulitple antennas we have at our campus at FH Aachen. One was of course our main Yagi-antenna on top of the roof of the Faculty of Aerospace Engineering at the Hohenstaufenallee but we also had the chance to use a Yagi-antenna at Faculty of Electrical Engineering at the Eupener Straße. On top of that we set up a mobile antenna at the Aachen observatory. We received some interesting telemetry the analysis is still ongoing. Stay tuned!

Letzten Samstag hatten wir die Chance Venta-1 sowie Robusta-1B mit mehreren Antennen zu tracken! Neben unserer Yagi-Hauptantenne auf dem Dach der Hohenstaufenallee am Fachbereich 6 Luft- und Raumfahrttechnik hatten wir auch die Chance die Yagi- Antenne an der Eupener Straße am Fachbereich 5 Elektrotechnik zu benutzen. Darüber hinaus haben wir eine mobile Bodenstation an der Sternwarte Aachen installiert gehabt. Mit dieser Konfiguration konnten wir spannende Telemetrie empfangen. Die Analyse steht noch aus.

So Finally I decoded C-Stars cw telemetry beacon,
playing back a hundred million of times the pre- recorded mp3 audio from the IQ-file in slowmo using a morse table. I was able to decode but took me ages to decode the first 2 lines...... Then PE0SAT proposed me to use FL-Digi and the 3rd and 4th Line was decoded immediately 🙂 Thank you man, you are awesome!
