Spacecraft Design - Electronic Sub-systems (ST7) (SPCE0007)

This module covers issues relevant to the electronic sub-systems of spacecraft, including power systems, attitude sensing and control, mechanisms, reliability, data handling. Topics include:

Comparison of spacecraft electronic systems to an equivalent ground based unit.
	Power Systems - Solar cells, solar arrays; storage cells; regulation dissipative and non-dissipative, regulators linear and switched mode, noise reduction, filters, supply monitoring, decentralised regulation.
	Attitude sensing and control - Earth and Sun sensors, charge coupled devices, wedge and strip, crossed anode, magnetic sensors, search coil and fluxgate, magnetic torquers.
	Mechanisms & Housekeeping - Control monitoring; optical and magnetic, pyrotechnic actuators, bridge techniques.
	Harnesses - EMC magnetic and electric coupling, shielding efficiencies for near and far field, EMC outgassing ports, connector types, low and high voltage, printed circuit board types.
	Reliability - Design techniques, heat dissipation, latch-up, interface and single point failures, housekeeping requirements, components specification, failure rates, fabrication, radiation testing, effect of radiation, displacement and ionisation damage, transients effects, designing for radiation protection.
	Analogue design - Charge sensitive amplifiers, noise considerations, practical circuits, pulse shaping circuits, unipolar and bipolar pulses, base line depression, pulse pile-up, low frequency measurements.
	Example sessions - Electrical hardware circuits for past and present space missions will be described and demonstrated utilizing the project’s development circuit boards.

This module studies the representation of the Mexican revolution in literature and muralism. We will cover the life-course of a phenomenon that, although an...
