There have been many terrible affairs in Russia in recent years,so the security department which assumes the mission of protecting the VIP becomes a focus in the world.

The shooting for security personnel is required to combine with security strategies,reform shooting movements,change shooting distances,shorten shooting time,extinguish moving targets in the movement,carry on actual combat-like dry shooting and red vs blue resistant shooting training.

The American security department win the compliment of craft brother around the world by their super excellence personal characters and qualities,the advanced security technical equipment,the tightly safe mechanism and the outstanding achievement.

Integration and analysis of intelligence based on multi-node guard zone;

The early-warning satellite is a important part in the NMD.

In this paper, coordinated attitude control law for an early-warning satellite with mobile sensors is proposed based on the conservation of angular momentum.

It is important to counter early-warning satellite for peoples to researching.

Based on researching the theory of the DSP early warning satellite,the characters of the initiative trajectory and the characters of the tail-flame s infrared radiation of the TBM are analyzed.

This paper finished the model design of the early warning satellite on the basis of system simulation, introduced system function, system construct and the key method of system programming.

According to the requirement of application and design of early warning satellite covering with the northern hemisphere of earth,the project of non-isomorphic early warning satellites constellation is put forward using coverage characteristics of ellipse orbit,which is composed of ellipse orbit satellites and equator circle orbit satellites.
