This paper presents the development of sun safe controllers which are designed to keep the spacecraft power positive and thermally balanced in the event an anomaly is detected. Employed by NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE), the controllers utilize the measured sun vector and the spacecraft body rates for feedback control. To improve the accuracy of sun vector estimation, the least square minimization approach is applied to process the sensor data, which is proven to be effective and accurate. To validate the controllers, the LADEE spacecraft model engaging the sun safe mode was first simulated and then compared with the actual LADEE orbital flight data. The results demonstrated the applicability of the proposed sun safe controllers.

“…The aforementioned control law (Eq. [18]) has been proven to be globally, asymptotically stable for a fully controllable spacecraft in the absence of disturbance torques as long as the control gain matrices are positive definite [Starin and Bourkland, 2007b]. Since 3 Cat-2 only employs magnetic actuation, the effectiveness of this control mode will be assessed through computer simulation.…”

This work describes the attitude determination and control system (ADCS) of ³CAT-2, a six-unit CubeSat scheduled for launch this 2016. The ADCS of 3 CAT-2 aims at controlling the satellite in orbit and fulfilling the pointing requirements imposed by the mission. The attitude control system implemented in 3 CAT-2 will be used to point the antennas towards the Earth to perform altimetry tests, orient the solar panels towards the Sun to maximize power input when battery levels are critical, and reduce the tumbling motion of the satellite after the deployment phase. In order to guarantee pointing requirements for remote sensing purposes, an active three-axis attitude determination and control system is considered.
