Path Planning for Global-Positional-System-Guided Indirect Fire Weapons
Richard J. Kenefic · Journal of Aerospace Computing Information and Communication · 2008
Global-positioning-system-guided indirect fire weapons can precisely engage high-value targets at long range, and the use of these weapons has been contemplated in complex terrain with obstacles and restricted airspace. Path planning for loitering weapons, such as unmanned aerial vehicles, has been well studied in the recent literature, but no path planning methods for global-positioning-system-guided indirect fire weapons are currently available.Thispaperpresentsapathplanningmethodforthiscasebymodifyingaframework commonly used for loitering weapons.
