Patent ID: 7266446

Claim:
A helmet mounted tracking system for target designation, comprising: an airplane azimuth sensor configured to determine an azimuth heading for an airplane; a helmet mounted azimuth sensor configured to determine an azimuth heading for a helmet that is worn by a pilot; an airplane pitch sensor configured to determine a pitch for said airplane; a helmet mounted pitch sensor configured to determine a pitch for said helmet that is worn by said pilot; a processor in operative communication with said airplane azimuth sensor, said helmet mounted azimuth sensor, said airplane pitch sensor, and said helmet mounted pitch sensor, wherein said processor is configured to process instructions digitally from each of said sensors to track the target and establish the target position by determining a target pitch and a target azimuth; and a memory having computer readable instructions configured to calculate said target azimuth by calculating an azimuth difference between said azimuth heading for said helmet and said azimuth heading for said airplane, and configured to calculate said target pitch by calculating a pitch difference between said pitch heading for said helmet and said pitch heading for said airplane.
