Abstract

A method for providing user interactive actual time networked surveying is disclosed. In one embodiment, a network connection is established between a survey instrument and a central computing device. In addition, a user session is established with the central computing device. Survey measurement data obtained with the survey instrument is transmitted to the central computing device. In addition, correction data from a virtual reference station (VRS) is received at the central computing device. The user session is allowed to direct the processing of the received survey measurement data including one or more real time kinematic calculations at the central computing device. The output of the processing of the received survey measurement data is provided to one or more authorized devices having a connection to the central computing device, the output provided in a concrete and tangible format.

Claims

1. A method for providing user interactive actual time networked surveying, said method comprising:

establishing a network connection between a survey instrument and a central computing device;

establishing a user session with the central computing device, the user session associated with the survey instrument;

transmitting, to the central computing device, survey measurement data obtained with the survey instrument;

receiving, at the central computing device, correction data from a virtual reference station (VRS);

allowing said user session to direct the processing of the received survey measurement data including one or more real time kinematic calculations at the central computing device; and

providing the output of the processing of the received survey measurement data to one or more authorized devices having a connection to said central computing device, said output provided in a concrete and tangible format.

2. The method of claim 1 further comprising:

establishing a network connection between the survey instrument and a virtual reference station; and

establishing a network connection between the virtual reference station and the central computing device.

3. The method of claim 2 further comprising:

receiving the survey measurement data at the virtual reference station (VRS);

enhancing the received survey measurement data with corrections data from the VRS to enhanced survey measurement data; and

transmitting the enhanced survey measurement data to the central computing device.

4. The method of claim 1 further comprising:

establishing a network connection between a virtual reference station and the central computing device; and

transmitting correction data from the virtual reference station to the central computing device.

5. The method of claim 1 further comprising establishing a network connection between a plurality of computing devices and the central computing device.

6. The method of claim 5 further comprising providing access to two or more computing devices to the same set of survey measurement data.

7. The method of claim 6 wherein one of the computing devices comprises a portable computing device and one of the computing devices comprises a desktop computing device.

8. The method of claim 7 wherein two of the computing devices comprise portable computing devices.

9. The method of claim 1 further comprising computing one or more positions in one or more co-ordinate reference frames.

10. The method of claim 1 further comprising establishing a network connection between a portable computing device and the central computing device.

11. The method of claim 10 wherein establishing the user session is performed on the portable computing device.

12. The method of claim 10 further comprising:

generating status and/or quality information at the central computing device on the received survey measurement data; and

transmitting the generated status and/or quality information to the portable computing device.

13. The method of claim 10 further comprising establishing a network connection between the survey instrument and the portable computing device.

14. The method of claim 10 further comprising receiving the survey measurement data at the central computing device at a first epoch rate;

and

transmitting data to the portable computing device at a second epoch rate, where the first epoch rate is different to the second epoch rate.

15. The method of claim 10 wherein the survey instrument is in a first location and the second portable computing device is in a second location.

16. The method of claim 15 wherein the first location is a hazardous location.

17. The method of claim 15 wherein the first location is unsuitable for a human operator.

18. The method of claim 10 wherein the survey instrument is positioned on an unmanned vehicle.

19. The method of claim 1 further comprising executing a data collector application on the central computing device to facilitate receiving data at the central computing device.

20. The method of claim 1 further comprising executing several sets of real time kinematic calculations simultaneously.

21. The method of claim 20 further comprising calculating a user position from several base station base streams.

22. A user interactive actual time networked survey system comprising:

at least one user selectable survey device from a pool of selectable survey devices;

a measurement data receiver module configured to receive raw measurement data from said at least one user selectable survey device and correction data from at least one virtual reference station (VRS) in actual time;

a measurement data processing module for processing said raw measurement data in conjunction with said correction data in actual time to generate actual time corrected measurement data; and

a graphical user interface (GUI) for presenting said actual time corrected measurement data in a user understandable format.

23. The system of claim 22 further comprising:

a network accessible data repository to store said raw measurement data and said corrected measurement data, said data repository having real-time multiple user accessibility.

24. The system of claim 23 wherein said network accessible data repository stores said correction data from said at least one VRS.

25. The system of claim 22 further comprising:

a current status information module to provide current status information for said at least one user selectable survey device on said GUI, said current status information selected from the group consisting of;

position, satellites in view and battery level.

26. The system of claim 22 wherein said correction data is automatically selected and automatically applied to said raw measurement data to generate said corrected measurement data and said corrected measurement data is automatically provided to said GUI.

27. The system of claim 22 wherein said correction data is user selected and applied to said raw measurement data via user input to generate said corrected measurement data.
