Abstract :
AeroAstro has adopted several advances in technology and architecture that have enabled significant reduction in cost and increase in flexibility for multiple nanosatellite missions. This Bitsy TM Spacecraft Kernel technology will enable recurring spacecraft mission costs of under ε, including space and ground systems and launch interfaces. This is made possible by: a standardized core of spacecraft capabilities based on commercial-off-the-shelf technologies; and miniaturization, which reduces recurring costs and makes a minimal demand on launch vehicle services. The spacecraft `kernel´, as opposed to bus, does not have a traditional division into discrete subsystems, but rather manages power, thermal control, ACDS, C&DH, and communications in a package of a few kilograms. Bitsy´s small size, light weight, and unique extensible architecture enables a variety of customizations to be added as needed to expand the range of achievable missions. In principle, the size and complexity of payloads Bitsy can accommodate is limitless
