By describing a typical example of this system and the blue print of hardware and the flowchart of software  the reliable work of the system has been proved. The circuits of system are very simple and practical  and they can be used to realize all the functions of a pilotless airborne mapping equipment. It also has a strong anti-jamming capability due to its balanced transfer scheme with single transmitter and multiple receivers. It is very efficient in protecting the integrity and correctness of transmitted and received signals  avoiding the collision of signals through the bus  satisfying the communication among several micro-controllers in a single system and forming a special communication network. 2009 SPIE.
