Abstract:
1. A portable system for facilitating inclined shooting of projectile weapons, comprising: a ranging system capable of measuring a line-of-sight range from a current vantage point to a target that is elevated or depressed relative to the current vantage point; an inclinometer aligned in angular reference with the ranging system capable of measuring an inclination angle of a line of sight between the current vantage point and the target; and a processor in communication with the ranging system and the inclinometer, the processor capable of being configured to determine a predicted altitude-compensated inclined shooting trajectory at the line-of-sight range for a preselected projectile based on a difference in altitude between the current vantage point with respect to sea level and an altitude of a sighting-in vantage point with respect to sea level, the sighting-in vantage point being a vantage point at which a projectile weapon shooting the preselected projectile was sighted in.
