In a method for requesting network-derived position data from a mobile geographic position aware receiver, a mobile geographic position aware receiver having a first IP address is communicatively coupled with a first port on a router. A wireless transceiver is communicatively coupled with a second port on the router. A wireless communication device is communicatively coupled with a third port on the router. A processor is communicatively coupled with the router; the processor for executing a communications access command sequence. The command sequence comprises: testing for a wireless network connectivity; contacting a source of position data if wireless network connectivity exists; and generating a data message to be sent via the wireless transceiver if the wireless network connectivity does not exist, the data message comprising an Internet Protocol (IP) address of the router, an approximate current location of the mobile geographic position aware receiver, and a request for correction data.

Method and a system for communicating information to a land surveying rover located in an area without cellular coverage

Embodiments of the present invention pertain to methods and systems for communicating information to a roving positioning device. In one embodiment, a wireless communication device, a non-cellular wireless communication device, and a computer networking device for forwarding data packets are coupled with a bus. A request originating from a roving positioning device for a location-specific position data is received via the non-cellular wireless communication device. A controller coupled with the bus causes the request to be forwarded via the wireless communication device.

The present invention is a method and system for determining a geographic position. In one embodiment, a data message comprising pseudorange data for a designated location and pseudorange corrections for a designated region surrounding the designated location is created. The data message is sent via a cellular telephone connection to a base station located in the designated region. The data message is then transmitted from the base station to a mobile position determination unit using a radio transmitter.

Method and system for delivering virtual reference station data

A three dimensional structure is precisely positioned at a desired location. A viral model of the structure of interest is created and stored in a computer memory. Some time later, remote sensors are placed in selected positions on the structure of interest. The sensors are configured so as to provide real time location, attitude and orientation information regarding the structure and may consist of GPS remote units, tilt meters, gyro compasses, and pressure sensor. The position of each the remote sensors on the actual structure is also recorded in the computer memory so that the virtual model accurately reflects the configuration of the structure. As the structure is being positioned, the real-time location, attitude and orientation information produced by the remote sensors is monitored at a base station and used to update the virtual model. In this way, the virtual model accurately reflects the current location, attitude and orientation of the structure. The information so obtained can be displayed to a user as a graphical and textual representation of the current state of the structure. The desired location, attitude and orientation of the structure is also displayed, thereby allowing a user to adjust the current location, attitude and orientation of the structure so as to align the current position of the structure to desired position. As built reports are produced upon completion of the positioning operation.

The system for the remote computer assisted precise pile driving and rig drilling operations is disclosed. The system includes a base station, a computer assisted precise pile driving and rig drilling (CAPPDARD) system, and a communication link. The CAPPDARD system includes a moving platform including a piling rig and a mast, a location determination means, a computer, and a communication means. The CAPPDARD system can be operated manually or remotely from the base station.
