This paper introduces a new type of reinforced-handset system design based on loongson1A+BMN2200S,which mainly used in Individual-command system domain. And particularly introduces hardware compose of the computer,Neokylin-linux system porting,principle of BMN2200S, algorithm of GPS/BD realtime-decode. Experiments proved that this system can satisfy the military reliability and security demand,and have the traits of real-time and practicable.
