Spatial position mapping technique |
摘要 |
The exact position of a work location (24) is mapped by the aid of at least three differential Global Positioning Satellite (GPS) receivers (12, 14, and 16) situated proximate the work location. Each of the differential Global Positioning Satellite (GPS) receivers establishes its own exact position and transmits that information to a spatial positioning system receiver (18) at the work location that determines its position from the position of the individual differential Global Positioning Satellite (GPS) receivers.
