Department: Space and Climate Physics
This module aims to teach students about scientific instrumentation on satellites and spacecraft, their uses, design, operation and data processing. Specific topics include:
1. Spacecraft as observation platforms
Why go into space, space environment, space effects from Earth's surface, in situ measurements, remote sensing, space as a laboratory, impact of space studies.
2. Systems approach to measurements
Analysis, detection, signal processing, data encoding, control. Spacecraft interface and subsystems: accommodation, attitude control, power conditioning. Examples from solar system exploration.
3. Spacecraft-environment interactions
Spacecraft charging in low Earth orbit and geostationary orbit. Radiation damage effects. Background effects and their minimisation. Plasma influx, penetrating radiation, sunlight.
4. In-situ plasma measurements
