Abstract

A GNSS data collection system includes a pole mounted GNSS receiver and inclination sensors. A data collection module provides a data collection graphical user interface (GUI) visible on a hand-held data collector computer. The data collector computer is communicably coupled to the GNSS receiver and receives three-dimensional location data and inclination data for the range pole in real-time. A virtual level component uses the inclination data to display on the GUI real-time tilt information in the form of a virtual bubble level indicator. The inclination data and height of the range pole are used to calculate and display horizontal distance and direction to level the GNSS receiver.

Claims

1. A GNSS data collection system comprising:

a GNSS receiver disposed on a range pole, the GNSS receiver configured to generate three-dimensional location data for the GNSS receiver,

a plurality of inclination sensors disposed on the range pole in operative engagement with the GNSS receiver, the inclination sensors configured to generate inclination data for the range pole along mutually orthogonal x and y axes;

a hand-held data collector computer including a display;

a data collection module implemented by the data collector computer, and configured to generate a data collection graphical user interface (GUI) visible on the display;

the data collector computer being communicably coupled to the GNSS receiver and configured to receive from the GNSS receiver, the three-dimensional location data and the inclination data for the range pole in real-time;

a virtual level component implemented by the data collector computer, configured to use the inclination data to display on the GUI real-time tilt information for the range pole in the form of a virtual bubble level indicator,

the virtual level component configured to use the inclination data along with the height of the range pole to calculate and display with the GUI, a horizontal distance and direction to move the top of the range pole to level the GNSS receiver; and

an audio component configured to generate an audible signal that varies in pitch or frequency in accordance with the real-time tilt information to guide a user to the predetermined tolerance without requiring the user to view the display, wherein the audible signal varies in pitch or frequency as tilt of the pole approaches zero.

2. The system of claim 1, wherein the GUI is configured to display a bubble relative to a circle corresponding to a target position, with the bubble configured to move in real-time as the range pole supporting the GNSS receiver is tilted.

3. The system of claim 2, wherein the GUI is configured to selectively display the bubble inside the circle when the pole is oriented within a predetermined tolerance of the horizontal distance from level, and to display at least a portion of the bubble outside the circle when the pole is oriented outside the predetermined tolerance.

4. The system of claim 3, wherein the bubble selectively changes color when inside and outside the circle.

5. The system of claim 3, wherein the data collection module is configured to permit or refuse capture of the location data when the pole is respectively within or outside the predetermine tolerance.

6. The system of claim 5, wherein the data collection module is configured to automatically capture, without additional user interaction, the location data at predetermined intervals of distance and/or time once the pole is within the predetermined tolerance.

7. The system of claim 1, wherein the data collection module is configured to use the inclination data and the height of the range pole to adjust the location data to compensate for any inclination of the range pole, to generate corrected location information for the GNSS Receiver.

8. The system of claim 7, further comprising at least one directional sensor disposed on the range pole in operative engagement with the GNSS receiver, the directional sensor configured to generate direction data corresponding to the orientation of the GNSS receiver in a horizontal plane, the data collector computer being configured to receive from the GNSS receiver, the direction data for the GNSS receiver in real-time.

9. The system of claim 8, wherein the directional sensor comprises an electronic compass.

10. The system of claim 8, wherein the data collection module is configured to use the inclination data and the direction data to adjust the location data to compensate for any inclination of the range pole, to generate the corrected location information for the GNSS Receiver.

11. The system of claim 10, wherein the data collection module is configured to generate corrected location information for the GNSS receiver when the pole is tilted outside a predetermined tolerance.

12. The system of claim 1, wherein the data collection module is configured to capture and store the inclination data and location data for post-processing.

13. A method for producing a GNSS data collection system, the method comprising:

(a) providing a GNSS receiver configured for being disposed at the top of a range pole, the GNSS receiver configured to generate three-dimensional location data for the GNSS receiver;

(b) providing a plurality of inclination sensors in operative engagement with the GNSS receiver, the inclination sensors configured to generate inclination data for the range pole along mutually orthogonal x and y axes;

(c) providing a hand-held data collector computer including a display;

(d) configuring a data collection module, implemented by the data collector computer, to generate a data collection graphical user interface (GUI) visible on the display;

(e) communicably coupling the data collector computer to the GNSS receiver and configuring the data collector to receive from the GNSS receiver, the three-dimensional location data and the inclination data for the range pole in real-time;

(f) configuring a virtual level component, implemented by the data collector computer, to use the inclination data to display on the GUI real-time tilt information for the range pole in the form of a virtual bubble level indicator,

(g) configuring the virtual level component to use the inclination data along with the height of the range pole to calculate and display with the GUI, a horizontal distance and direction to move the top of the range pole to level the GNSS receiver; and

(h) configuring an audio component to generate an audible signal that varies in pitch or frequency in accordance with the real-time tilt information to guide a user to the predetermined tolerance without requiring the user to view the display, wherein the audible signal varies in pitch or frequency as tilt of the pole approaches zero.
