..Local Ionospheric Measurements Satellite..
..The Pennsylvania State University..

..Problem..
LionSat requires small attitude changes while in orbit as well as spin generation. If attitude changes are left uncorrected, the satellite’s orientation would make it unusable for the intended scientific measurements and cause deviation from its orbital path.

..Objective..
The project objective is to design a magnetic torquer attitude control subsystem for LionSat. The magnetic torquer consists of a cylindrical metallic core wrapped with wire, effectively creating an electromagnet that can be controlled by varying the current through the surrounding wire. The purpose of the solenoid is to create a magnetic field that will interact with the earth’s magnetic field in order to correct for small deviations in orbital attitude. Our finalized design for the magnetic torquer will be linked to a control system that will regulate the current flow scheme of the wire. The control system will consist of bi-directional control electronics that will allow current flow in both directions across the core.

..Processes..
  • Physical Design (core materials, dimensions, and turns)
  • Construction of Prototypes (winding, insulation, and design implementation)
  • Magnetic Moment Testing (magnetometer test)
