Control of satellite pointing direction is essential to all modern
satellites. Whether the satellites purpose is research,
surveillance, or for public use, on-board antenna’s must
constantly be communicating with ground stations. I have
designed and simulated a satellite control system that
operates using strictly torque coils as the system of control.
Torque coils consist of copper wiring wound many times and
a current running through the wires to generate a magnetic
field. The magnetic field generated by the copper wires will
tend to align itself with the Earth’s magnetic field. Although
torque coils can be very limiting and very slow this type of
design will save money, and weight. Additionally, torque coils
can be controlled by electricity so the satellite does not have
to carry any fuel. My research explores the different stages
of control required for an entire orbital mission.
