Method and system for the acquisition of high-accuracy coordinate information without the use of directed electromagnetic radiation
First Claim
1. A method of determining coordinates of a remote location based on where a shortest line-of-sight path from an angle measurement device intersects the terrain at a remote location within view of a scope of an angle measurement device, comprising the steeps of:
- a) identifying a point, using a computing device to obtain azimuth and elevation (altitude) angles of the scope from the angle measurement device and perform calculations to accurately determine position of the remote location, that is substantially on the shortest line-of-sight path which starts at the scope of the angle measurement device and traverses the remote location;
b) determining whether the point from step a) is above or below the surface of the terrain at that location;
c) repeating steps a) and b) until a point from step a) has been identified for which the distance between the point and the surface of the terrain is less than a selected value.

Abstract
A method for providing highly accurate coordinates and elevation of a remote terrestrial-based location is described. The method also provides for the determination of a number of high-accuracy values including the location and elevation of the point of observation, and the distance and bearing from the point of observation to the remote location. Also described is a method for compensating for unknown effects of the associated atmospheric refractivity, and errors in input data.
