Quantized hyperbolic and inverse hyperbolic object location system
First Claim
1. A radio frequency triangulation object location method for identifying the location coordinates of predetermined known geographical locations within a data base region wherein signals are transmitted via a vehicle unit for reception via at least three antennas, the method comprising the steps of:
- positioning the vehicle unit at each of the known predetermined geographical locations within the data base region;
transmitting signals for reception by the antennas from the vehicle unit at each of the predetermined geographical locations; and
determining base location coordinates for each of the known predetermined geographical locations within the data base region in response to the signals transmitted via the vehicle unit at each of the predetermined geographical locations, wherein the signal strength of the signals received by each antenna exceeds a predetermined minimum level.

Abstract
An object location system wherein signals are transmitted or received via more than one transmit station and wherein the objects receive signals from the transmit stations or transmit signals for reception by the treatment stations within a data base region and wherein location coordinates are established in response to the signals received by the transmit stations or in response to the signals received at the object from the transmit stations at a predetermined number of geographic locations within the data base region by positioning the object receiver or transmitter at each of the predetermined geographic locations. The objects are located within the data base region by comparing location coordinates determined in response to signals received at the transmit stations or in response to signals received at the objects with the established location coordinates.
