SENSOR DATA SIMULATOR AND SENSOR HARDWARE SIMULATOR TO BE USED IN INTEGRATED VERIFICATION SYSTEM OF ATTITUDE DETERMINATION AND CONTROL FOR SMALL SATELLITE

摘要

A sensor data simulator and a sensor hardware simulator used in an integrated verification system of the attitude determination and control for small satellites are provided to embody a verification system at a low cost by applying an orbit condition and hardware characteristics of a satellite sensor. A sensor hardware simulator(300) includes a serial communication unit(310), a controller(320), and a multiplexer(330). The serial communication unit receives a sensor output value from a sensor data simulator(200). The controller converts a digital sensor output value which is received from the serial communication unit, into an analog sensor output value and outputs the analog sensor output value. The multiplexer outputs the analog sensor output value which is inputted from the controller, to an instruction and data processing unit(400) through a channel according to a channel control signal inputted from the controller.
