Aerospace Specialist Laboratory

The institute of Space Systems conducts the Aerospace Specialist Laboratory in conjunction with the Satellite technology and satellite operations lecture (Satellitentechnik und Satellitenbetrieb mit Labor, Master).

Competence field laboratory (B.Sc.)

The competence field laboratory in the bachelor's degree mechanical engineering (specialization in aerospace engineering) takes place under the direction of the Institute of Jet Propulsion and Turbomachinery. Contact person is Tim Wittmann, M.Sc. (This email address is being protected from spambots. You need JavaScript enabled to view it.)

Laboratory: Fachlabor zur VL Satellitentechnik und -betrieb (Master)

Semester: SoSe 2020

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 2020. 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 and Satellite Operations (module Satellitentechnik und Satellitenbetrieb mit Labor). The conduction of the laboratory itself is organised via Stud.IP. Considering the organisation and registration for the laboratory, detailed information are to be found in the Satellite Technology and Satellite Operations Stud.IP-event or can be requested from the responsible contact person.

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.
