Abstract

Abstract A system and method for tracking its own geographic position, comparing that position with stored boundary data, i.e., a ''''map, '''' and responding whenever the apparatus crosses the boundary as defined on the ''''map.'''' In operation, inertial measurements are processed to produce signals representative of computed position. These signals are compared with stored positional data, whereupon a response mechanism may be activated. The system includes a means for determining its motion state so that the system can calibrate itself when there is no significant motion. Thus, the system offers new options for the use of conventional as well as nuclear weapons, as well as for other type of vehicle position determination.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 144 words
A geographic position locator system comprising: means for determining the system''s geographic position including means for evaluating motion thereof; means for comparing the determined position with stored boundary data; means for determining the condition of the system; means responding to output signals from said comparing means and said condition determining means for effecting the condition of an associated vehicle; mean for providing the necessary power distribution from an associated power source throughout the system; said first-mentioned means comprising an inertial measuring means for determining at least gravity and acceleration forces, a navigation computer means connected to receive at least acceleration output signals from said inertial measuring means and for directing at least gyrotorquing signals thereto; said means for evaluating motion comprising a motion evaluator connected to receive motion signals and connected to transmit to said navigation computer means signals defining start and stop motions.
Claim 2
Dependent Claim 144 words
A geographic position locator system comprising: means for determining the system''s geographic position including means for evaluating motion thereof; means for comparing the determined position with stored boundary data; means for determining the condition of the system; means responding to output signals from said comparing means and said condition determining means for effecting the condition of an associated vehicle; mean for providing the necessary power distribution from an associated power source throughout the system; said first-mentioned means comprising an inertial measuring means for determining at least gravity and acceleration forces, a navigation computer means connected to receive at least acceleration output signals from said inertial measuring means and for directing at least gyrotorquing signals thereto; said means for evaluating motion comprising a motion evaluator connected to receive motion signals and connected to transmit to said navigation computer means signals defining start and stop motions.
Claim 3
Dependent Claim 49 words
The system defined in claim 1, wherein said navigation computer means includes a navigate mode and a partial calibration mode, and wherein said start and stop motion signals from said motion evaluator are respectively directed to said navigate mode and said partial calibration mode of said navigation computer means.
Claim 4
Dependent Claim 23 words
The system defined in claim 2, wherein said motion signals received by said motion evaluator are directed thereto from said navigation computer means.
Claim 5
Dependent Claim 35 words
The system defined in claim 3, wherein said means for comparing the determined position with stored boundary data comprises an area comparator means connected to receive a geographic position determination from said navigation computer means.
Claim 6
Dependent Claim 26 words
