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.

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.

Today, besides doing some theoretical revisions about satellite communications, we made a short satellite tracking session during which we received NOAA-18, Grifex and SKcube:

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!

Lets us help this early bird, the Stars-C!
Tomorrow at 06:00 we will attempt to send the command to deploy the Daughter from the Mothership of STARS-C in presence of Prof. Masahiro Nohmi at Compass-2 / DL0FHA. Hopefully it will work despite the undeployed receiver antenna. We will try (if needed) a second time during the pass of 07:35. Downlink beacon frequency is 437,245MHz. Wish us good luck 🙂

Hey Guy's, I have to face one dilemma: Inflatesail,
Lituanicasat-2 and D-Sat are approaching our air- space. Which one should I track? 🙂 PE0SAT Mike Rupprecht

Tracking Funcube 1 few minutes ago. AOS:19h23utc Elmax:62.5° LOS:19h35utc. Perfect reception, we got a lot of packets, almost from horizon to horizon using SDR receiver: RTL2832 with 2m Yagi Array connected. We can provide the binary file if wanted. Just feel free to ask.

NOAA-19 some moments ago, captured over ESA Websdr located in Noordwijk / The Netherlands. Although the bandwidth via websdr is a lot smaller, one can get interesting results if you follow the doppler manually:

Yeeaah! We faced how to decode LituanicaSat-2 using Mike Ross's AGWPE and Mike Rupprecht's Online Kiss and his corresponding Visualization tool! It's beginning to make even more fun!
