First Claim
Patent Images
1. A geographical location communication system comprising:
- a plurality of references, each having reference positional data;
a mobile unit within a region covered by a reference, the mobile unit capable of determining the geographical location (geo-location) of the mobile unit; and
a locator to receive compressed geo-location data of the mobile unit and to determine the geo-location of the mobile unit by comparing the compressed geo-location data against the reference positional data of the reference covering said region.

Abstract
A system and method for efficiently transmitting geographical location data of mobile units is disclosed. The invention allows less than the complete geographical location data to be transmitted and reported to a locater. Using fixed geographical references, the locater then interpolates the complete geographical location of mobile units from the reported data.

6. A method for communicating geographical location comprising:
-
establishing a plurality of references, each having reference positional data and an identification (ID) code;
determining the geographical location (geo-location) of a mobile unit operating in a region;
receiving a compressed geo-location data of the mobile unit and a reference data of a reference covering said region; and
recovering the geo-location of the mobile unit by comparing the compressed geo-location data against a reference positional data, said reference positional data obtained from the received reference data. - View Dependent Claims (7, 8, 9, 10)
