Patent ID: 7595867

Claim:
A method of mobile radio positioning aided by a single fan laser, wherein a rover comprises a mobile radio positioning system (Mobile RADPS) integrated with a mobile laser detector; and wherein said single fan laser comprises a stationary laser transmitter integrated with a stationary radio positioning system (Stationary RADPS); said method comprising: (A3) generating an electronic timing pulse every time a known position of said laser beam passes a single reference mark in said laser transmitter; (A4) generating a plurality of time tags by time-tagging each said electronic timing pulse by using said stationary radio positioning system (Stationary_RADPS); (A5) generating a low-passed filtered estimate of an angular rate of said laser beam by using said plurality of time tags; wherein each said time tag is indicative of a time instant when said reference mark is crossed by one said electronic timing pulse; (A6) transmitting said low-passed filtered estimate of angular rate of said laser beam and transmitting said plurality of time tags to said rover via said wireless communication link; (B) detecting said single sloping fan beam generated by said stationary fan laser transmitter by using said mobile laser detector; and (C) timing said fan laser beam strike at said rover's location and using said timing of said fan laser beam strike at said rover's location to improve an accuracy in determination of position coordinates of said rover.
