An innovative 12U CubeSat to demonstrate polarized light navigation and microgravity measurement

Most of the CubeSats have a volume range from 1U to 3U, which limits their applications due to the difficulty of miniaturizing payloads. To facilitate the needs on a larger but low-cost satellite platform, the AOXiang (AOX) project has been developed by Northwestern Polytechni ...

In this paper, a redundant and integrated avionics for 12U CubeSat is presented. The main innovation is to propose a method to enhance system reliability and fault tolerance based on the COTS(Commercial Off-The-Shelf) devices, as well as to deal with system recoverability for unk ...
The speed control accuracy of micro-reaction wheel was improved in order to meet the accuracy requirements for the attitude control of pico-nano satellites and CubeSat. The speed measuring and control system was designed with the switch-type Hall sensor, a speed estimation method ...
