MOVE-ON

MOVE-ON - High altitude pseudo satellites

MOVE-ON is developing a High Altitude Pseudo Satellite (HAPS) as a experimental and testing platform for future satellite missions. Scientific and also technical payloads are build by the students, staff of the chair or external costumers. MOVE-ON is building on the experience of past satellite missions of the chair and the MOVE missions.

Mission Concept

The system is designed to operate for 5 h, with a flight time of about 2 h. A gondola with the system will be attached to a helium balloon with in the regulations of the balloon class ”light”. On a sunny day it will then be launched from the campus site of the Technical University Munich in Garching. In flight the system has a downlink which provides information about the position. All payload data and and a set of telemetry data will also be send. After an ascent of roughly 2 h the balloon will explode, because of the pressure difference of in and outside. A rapid descend follows. With the attached parachute a descent velocity of about 10 m/s is to be expected. During the whole flight
a mobile ground station in addition to the LRT roof antenna will track the position. This will help with a fast recovery of the system after descent.

History

From 2017 to 2018 in summary three successful Balloon launches did take place. With these missions we could test very cost effective the equipment for several satellite missions.

Hydrogen

During Summerschool in 2017 the first Balloon Mission, MOVE-ON Hydrogen was successfully launched.

About 35 students from the fields of informatics, physics, electrical and mechanical engineering participated in the first project. The system was designed very simply then, the focus was on getting experience with a HAB.
The students also developed a scientific and a technological payload in the context of student research projects. Part of the funding for the project was provided by Singronic GmbH, who developed another payload.
The duration of the flight amounted to two hours and the Balloon reached an impressive peak height of 35km. During flight, insightful data and breathtaking photos were captured.

Helium

A bigger team worked on the new systems, which had many new features. A very special payload by the Max Planck Institute for Extraterrestrial Physics was on board. It measured the scattered light of the sun on the upper atmosphere. The scientists wanted to know if such a balloon could be used to look at stars also during the day.

Lithium

The Lithium mission had the main goal to develop a new bus system for further satellite missions. CAN bus was tested with the STM32L4 micro controller.

We launched on the October 13th 2018. The event was part of the TUM Tag der
offenen Tür. The gondola landed near the Autobahn exit Jengen. We recovered it on the same day as the launch late in the evening. The balloon exploded perfectly since we could find nothing but the small bit which had the rope attached to it. The gondola it self survived it the impact very good. No damage has been seen.

CAN bus was successfully deployed and will be used in further missions.
