Abstract

Abstract A simplified guidance system for air-to-air missiles where the pilot adjusts his helmet sight to compensate for missile errors and this information is fed to a computer which computes correction data from error information, aircraft position information and missile position information, correction data is then sent via a radio link to the missile control system which changes the flight path accordingly.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 145 words
A simplified high accuracy guidance system comprising: an aircraft missile launching platform including a pilot controlled protective helmet, at least one missile adapted to be launched from said platform; reticle sighting means located in said helmet for the pilot to observe a target; computer means connected to the helmet sighting means for establishing a line of sight to the target; an internal reference package means connected to said computer means for determining the position of the launching platform; radio frequency transmitter and receiver means for communicating changing line of sight data to the missile; a missile flight control system including a radio frequency transmitter and receiver means for changing the flight path of the launched missile based upon data received; internal reference means for determining the position of the missile relative to the target and means for communicating position information to the said computer means.
Claim 2
Dependent Claim 145 words
A simplified high accuracy guidance system comprising: an aircraft missile launching platform including a pilot controlled protective helmet, at least one missile adapted to be launched from said platform; reticle sighting means located in said helmet for the pilot to observe a target; computer means connected to the helmet sighting means for establishing a line of sight to the target; an internal reference package means connected to said computer means for determining the position of the launching platform; radio frequency transmitter and receiver means for communicating changing line of sight data to the missile; a missile flight control system including a radio frequency transmitter and receiver means for changing the flight path of the launched missile based upon data received; internal reference means for determining the position of the missile relative to the target and means for communicating position information to the said computer means.
Claim 3
Independent Claim 63 words
A method for guiding air-to-air missiles using a helmet mounted sight including: launching a missile from an airborne piloted launching platform; observing the target through the helmet mounted sight; observing the missile on the line-of-sight path to the target; moving the helmet and line-of-sight path away from the target, an amount sufficient to compensate for errors whereby the missile will strike the target.
Claim 4
Independent Claim 63 words
A method for guiding air-to-air missiles using a helmet mounted sight including: launching a missile from an airborne piloted launching platform; observing the target through the helmet mounted sight; observing the missile on the line-of-sight path to the target; moving the helmet and line-of-sight path away from the target, an amount sufficient to compensate for errors whereby the missile will strike the target.
