Positioning system for projecting a site model
First Claim
1. A positioning system, comprising:
- a database for storing a site model, wherein the site model includes data indicative of a desired geography of a site environment and an actual geography of the site environment;
a first receiver for generating digital signals representing a real time position in three-dimensional space of at least a portion of a machine as the machine traverses the site environment;
a processor for receiving the signals and updating the site model to determine a difference between the data indicative of the desired geography and the data indicative of the actual geography; and
a display for projecting the site model onto at least one surface of an operator station of the machine so that an operator may simultaneously view the site model and the site environment.

Abstract
A positioning system is disclosed. The positioning system has a database for storing a site model. The site model has data indicative of a desired geography of a site environment and an actual geography of the site environment. The positioning system also has a first receiver for generating digital signals representing a real time position in three-dimensional space of at least a portion of a machine as the machine traverses the site environment. The positioning system further has a processor for receiving the signals and updating the site model to determine a difference between the data indicative of the desired geography and the data indicative of the actual geography. The positioning system also has a display for projecting the site model onto at least one surface of an operator station of the machine so that an operator may simultaneously view the site model and the site environment.

14. A method for providing positioning data to an operator, comprising:
-
storing data indicative of a desired geography of a site environment; storing data indicative of an actual geography of the site environment; receiving a real time position in three-dimensional space of at least a portion of a machine as the machine traverses the site; updating the data indicative of the actual geography of the site environment based on the real time position; determining a difference between the data indicative of the desired geography and the data indicative of the actual geography in real time; updating and storing the difference; and projecting data onto at least one surface of an operator station so that the data indicative of the desired geography, the data indicative of the actual geography, and the difference may be viewed simultaneously with the site environment by an operator. - View Dependent Claims (15, 16, 17, 18)

19. A machine having a positioning system, comprising:
-
a first receiver for generating digital signals representing a real time position in three-dimensional space of at least a portion of the machine as the machine traverses a site environment; a first processor for receiving the signals; a database for storing a site model, wherein the site model represents the desired geography of the site environment and the actual geography of the site environment; a second processor for receiving data from the first processor to update the site model and to determine a difference between the desired geography and the actual geography, wherein the difference is updated in real time and stored in the database; a display for projecting the site model onto at least one surface of an operator station of the machine so that an operator may simultaneously view the site model and the site environment; and a tool, wherein the tool includes a second receiver for generating digital signals representing a real time position of the tool in three-dimensional space. - View Dependent Claims (20)
