Wireless guidance system
First Claim
1. A method for guidance of a device, comprising:
- receiving signals from at least one wireless base station indicating at least a respective position thereof;
determining the current position of said device using said received signals;
calculating a vector between the determined current position and a predetermined desired destination for said device; and
using said calculated vector to make any required trajectory corrections to said device'"'"'s current trajectory for guiding said device to the desired destination.

Abstract
A wireless means of guidance for a device in accordance with the present invention includes receiving signals from at least one wireless base station indicating at least a respective position thereof, determining the current position of the device using at least the information contained in the received signals, calculating a vector between the determined current position and a predetermined desired destination for the device, and making trajectory corrections to the device'"'"'s current trajectory so as to guide the device to the desired destination. In addition to the information contained in the received signals, the guidance system may also use stored information regarding parameters, such as the location, communication protocols and operating frequencies of the wireless base stations, as well as previous position information, for determining a current position for the device.
