From the project
Our experiment aims to evaluate the use of optical navigation with Commercial-off-the-Shelf (COTS) products for use in spaceflight applications. To conduct the experiment, an autonomous attitude determination and control system (ADCS) employing an optical navigation system (ONS)
Our experiment aims to evaluate the use of optical navigation with Commercial-off-the-Shelf (COTS) products for use in spaceflight applications. To conduct the experiment, an autonomous attitude determination and control system (ADCS) employing an optical navigation system (ONS) will be designed to control a 1U CubeSat, codenamed Commercial Optical Navigation Satellite (CONSat).
