Technical Session XIII: Advanced Technologies 2
Abstract
The THEMIS project, a NASA MIDEX program managed by the University of California at Berkeley, was launched in February 2007 and was the first NASA mission to launch five science satellites simultaneously. The low power requirements and tight volume constraints of the mission were the major drivers with the design of the Bus Avionics Unit. The Bus Avionics Unit performs the functions of a primary Bus computer, Communication I/O interface, and Power Control Electronics for the satellite. It consists of five modules, consumes less than 6.4 watts, and weighs only 2.8 kg. This optimized design was a major enabler for this mission due to its compact design and low power consumption.
