An Intelligent Attitude Determination And Control System Concept For A Cubesat Class Spacecraft, Jeremy Straub

An attitude determination and control system (ADCS) is used to orient a spacecraft for a wide variety of purposes (e.g., to keep a camera facing Earth or orient the spacecraft for propulsion system use). The proposed intelligent ADCS has several key features: first, it can be used in multiple modes, spanning from passive stabilization of two axes and unconstrained spin on a third to three-axis full active stabilization. It also includes electromagnetic components to ‘dump’ spin from the reaction wheels. Second, the ADCS utilizes an incorporated autonomous control algorithm to characterize the effect of actuation of the system components and, …

The OpenOrbiter program aims to develop a low-cost framework to facilitate the development of CubeSat-class spacecraft (small spacecraft with nominal dimensions of 10 cm x 10 cm x 10 cm) for a parts cost of less than $5,000. To validate the framework that has been developed, a prototype unit will also be fabricated and tested in low-Earth orbit. In addition to validating the development of Open Prototype for Educational Nanosats (OPEN) framework, the spacecraft will perform on-orbit science. One aspect of the science mission will be to demonstrate and characterize the efficacy of two types of image processing. To this …
