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 …

Attitude determination and control is one of the most important subsystems on any satellite, allowing the spacecraft to sense and control its orientation while in orbit. Attitude sensing is achieved by measuring the satellite’s acceleration, rotation, and it’s alinement to Earth’s magnetic field. With its orientation determined, a satellite can use one or several different techniques to regulate its motion. One methods is to use of a pseudo-passive system of electromagnets (called magnetorquers) powered at specific times to use magnetic fields generated by the Earth to exert force on the spacecraft, thereby controlling the rotation of the satellite and facilitating …
