In general, artillery ammunition refers to the type of ammunition used for cannons among the categories of firepower used to conduct firepower combat. In this case, firepower combat refers to a combat execution method in which artillery integrates available firepower assets as a key function of firepower that obstructs the enemy's maneuvering. In addition, a guided weapon refers to any type of weapon that can detect/track/precisely strike a target through navigation devices and searchers inside/outside of the weapon.

Artillery rounds are fired according to firing specifications (eg, angle and rate of fire, etc.) to hit the same target from multiple door guns belonging to at least one battery.

The artillery precision guidance technology used for guided missiles can be roughly divided into two categories. One is a ballistic correction bullet, in which a ballistic correction kit is installed to perform guided control of the shell, and the other is a type of gun that accommodates the control wing in the ammunition and deploys the control wing in a certain section after firing to perform guided control. It is a missile launcher. That is, 　cannon firing 　guided shells are shells that have a control wing mounted on the initial shell and then deployed after being fired to receive a deployment command to perform guided control.

In a conventional weapon system, weather data is required when calculating a shooting specification for calculating the trajectory of a conventional shell (eg, unguided artillery projectile). At this time, in order to acquire the weather data, the existing method utilizes the data measured after sending a sensor to the weather observation balloon at the current location and flying.

However, when using a weather observation balloon, the observation balloon may fly away from the location to measure the weather information, so there is a problem in that the desired high-altitude weather observation is difficult.

In addition, if the weather observation balloon is used in a battlefield environment, there is a risk that the position of the friendly force is exposed to the enemy due to the slow movement speed of the weather observation balloon. And, during the weather observation, there was a problem that the tactical freedom was significantly lowered because it could receive a preemptive strike from the enemy.
