Mortar fire direction with multiplatform mobile application

Abstract

Mortar is one of the weapons that is still used for warfare. In determining the direction of mortar firing there are still using conventional method with plotting board. Then it takes a portable calculator that is quick and accurate in determining the angle of elevation and angle of azimuth. So it is proposed that this mortar fire direction is a mobile application with multiplatform development method that can run on Windows, Android, and iOS operating systems. The result of this research is a prototype mobile application that provides a report of elevation angles and azimuth angles rather than mortar quickly and accurately to the intended goal.
