Surveying system
First Claim
1. A surveying system for a construction site, comprising:
- a restricted antenna system including a plurality of fixed location antennas each defined by a set of location data associated with a specific deployment position at the construction site; and
a computing device including a data processor, a display screen, and a Global Positioning System (GPS) receiver, the computing device being receptive to data for distances between current positions of the computing device within the construction site and one or more of the plurality of fixed location antennas over a data transfer link to the restricted antenna system;
wherein the computing device is loadable with one or more project drawings corresponding to the construction site displayable on the display screen, a position marker being overlaid on the display of the project drawing at a position thereon corresponding to a computing device location value selectively derived from the spatial data and the location data of one or more of the fixed location antennas received by the computing device, and as generated by the GPS receiver and associated with a current position of the computing device within the construction site, the display of the project drawing being adjustable in response to a change in position of the computing device within the construction site.

Abstract
A surveying system for a construction site has a restricted antenna system with a plurality of fixed location antennas each defined by a set of location data associated with a specific deployment position. The surveying system also has a computing device with a data processor and a display screen. A communications module establishes a data transfer link with the restricted antenna system over which spatial data for distances between current positions of the computing device and one or more of the plurality of fixed location antennas are received. The computing device is loadable with project drawings corresponding to the construction site and displayable on the display screen. A position marker is overlaid on the display of the project drawing at a position thereon corresponding to a computing device location value derived from the spatial data and the location data of one or more of the fixed location antennas.

13. A method of navigating a construction site with a computing device, the method comprising:
-
retrieving, with the computing device, one or more project drawings from a central database, the project drawings including at least one element defined by a set of position coordinates corresponding to a position within the construction site; selectively receiving, from a restricted antenna system receiver in communication with a restricted antenna system including a plurality of fixed position antennas located within the construction site, and an on-board GPS receiver on the computing device, a set of coordinates corresponding to a current position of the computing device within the construction site; displaying the one or more project drawings on the computing device; overlaying a device position marker on the display of the one or more project drawings based upon the set of coordinates from the location reporting system; and adjusting the overlay of the device position marker in response to a change in the current position of the computing device within the construction site. - View Dependent Claims (14, 15, 16, 17)
