The Military Satellite Communication System-II is a follow-up system to the ANASYS system and is an all-army communication network with enhanced mobility, speed, and wide area. In normal times, it is operated in parallel with optical and microwave communication networks, but in case of emergency, this is operated as the main communication network.

As a military independent satellite, it supports various satellite terminals, and the transmission capacity has been increases by expanding the frequency band and applying a higher-order modulation method. In addition, through the development of new terminals, the mobility of the tactical battalion is improved, and excellent communication quality is guaranteed even in a poor radio environment.

The Military Satellite Communication System-II is an essential military power that ensures the exchange of information among surveilance and reconnaissance, command and control, and precision strike systems and command and control between tactical maneuvers, and is intended to ensure the successful execution of full maneuvers by the Armed Forces.
