Abstract

The primary motivation of the hardware is for the instruction of satellite control techniques through the usage of a common satellite actuator (reaction wheels) and sensors (rate gyroscopes). This demonstration features a single-axis rotating mock-satellite that can be used to allow hands on learning opportunities of satellite estimation, sensing, actuation and control. The platform allows for custom satellite control schema through the employment of a primary embedded satellite control board programmed with Simulink and a LabVIEW-based ground station. The small 6” x 6” x 4” satellite includes a Maxon EC-motor and controller, reaction wheel, Inertial Measurement Unit (IMU) used to sense one axis of spin rotation rate/angle, XBEE wireless transceiver to transmit and receive data, a custom interface printed circuit board, and an Arduino DUE microcontroller as the primary processing device. Clear acrylic satellite panels allow for observation of the primary components. The ground station includes a Maxon EC-motor, controller, and encoder, a vertical shaft supporting the satellite, wireless transceiver for communication, and a National Instruments myRIO for USB communication to a LabVIEW based graphical user interface (GUI) on a personal computer. An additional 3D-printed accessory can be installed for experimental demonstration of the principle of conservation of momentum.
