Drivenhet för satellitantenner

Sammanfattning

The task in this master thesis was to design and construct a prototype of a

satellite antenna driver unit. The unit is to be robust and work in cold

weather down to -40°C, so that it can be mounted on the roof of a minibus.

A microcontroller controls the H-bridges simultaneous, each connected to an

electrical motor. Hardware and software protections were implemented to

ensure that the antenna can not turn outside its allowed area and risk

breaking. The unit can output voltages at many different levels and

communicate at a multitude of signal standards.
