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).
Laboratory: Fachlabor zur VL Satellitentechnik und -betrieb (Master)
Semester: SoSe 2021
Organisation: Due to the continuing Corona regulations, the space technology laboratory will not be conducted as an in-situ event in the summer semester 2021, but as an online course. The structure and content of the laboratory are largely unaffected by this change (thematically and structurally similar to previous years). The laboratory will be held in combination with the course on Satellite Technology and Satellite Operations (module Satellite Technology and Satellite Operations with Laboratory). The introductory event on organisation and schedule of the laboratory will take place virtually on 21.04.2021, 1:15 pm and will be accessible via the following link: https://webconf.tu-bs.de/lor-nvk-jwd.
Recommended prerequisites: Fundamentals of Aerospace Engineering, Space Missions
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.
