Thedesign scheme and hardware structure are expatiated, including thef light control computer based on TMS320F2812 DSP, strapdownA ttitudeH eading Ref erence System (AHRS) which uses cheap M MS devices and the dualre dundancy buses which increase the communication reliability. light tests show that the system could satisfy the reliability and p recision needs of small UAV, and is a kind of lightweigh,t low cost schemew ith high integration.
