Aerospace Specialist Laboratory

The institute of Space Systems conducts the Aerospace Specialist Laboratory in conjunction with the Satellite Technology lecture (module Satellitentechnik mit Labor, Master).

Laboratory: Aerospace Specialist Laboratory for the lecture Satellite Technology (Master)

Semester: Summer semester 2022

Organisation: Due to the continuing Corona countermeasures, the Aerospace Specialist Laboratory (Raumfahrttechnikfachlabor) will not be held as a presence laboratory, but as an online event in the summer semester 2022. Structure and contents of the laboratory are mostly unaffected by this change (thematically and structurally similar to previous years). The laboratory will take place in combination with the lecture Satellite Technology (module Satellitentechnik mit Labor). The laboratory is organised via StudIP. However, the self-registration is disabled for the StudIP course. We will register you manually if you participated in the group allocation during the obligatory online introductory session on 27 April 2022 at 3 pm. Therefore, attending this introductory session is mandatory if you want to participate at the Aerospace Specialist Laboratory. You can join the introductory session via the BigBlueButton link: https://webconf.tu-bs.de/mar-t7c-py5-1mv. Further important information about this laboratory can be found in the here uploaded PDF file.

Recommended prerequisites: Fundamentals of Aerospace Engineering, Space Missions

Laboratory experiments

A total of six laboratory experiments from the field of satellite technology are to be conducted.

Experiment 1: Reception of an amateur radio satellite

With the satellite ground station of ERIG, the signal of an overflying amateur radio satellite is received, decoded and evaluated. Prior to the experiment, the ground track of the satellite is calculated from given orbital data, which is necessary to determine the antenna tracking. Additionally, the Doppler shift of the satellite frequency is used to characterise the overflight.

Experiment 2: Orbit determination for earthbound satellites

In this experiment, angle measurements of overflying satellites are acquired in the evening hours by a telescope. Subsequently, the orbit of the observed objects is calculated using the measured angles.

Experiment 3: Space Robotics

Robots occupy a prominent role in the exploration and in-situ processing of resources. In this experiment, a robot arm will be programmed and simulated for the construction of a lunar habitat.

Experiment 4: EyasSat - Electrical Power Subsystem

The education and training satellite EyasSat is used to actively teach students the basics of handling satellite systems in the course of the laboratory. In this experiment, the energy supply of the satellite is analysed by performing systems tests for the electrical power subsystem.

Experiment 5: EyasSat - Data Handling and Communications Subsystem

This experiment deals with the on-board computer and communication systems of EyasSat. Telecommand signals are sent to the satellite from a computer station and signals from the satellite are received as well as analysed via telemetry.

Experiment 6: Attitude Determination and Control Subsystem

Within the scope of this experiment, the fundamentals of satellite attitude determination and control are investigated. In this context, various programming tasks from the field of control theory have to be solved.
