Abstract

A survey instrument conveyance is disclosed. One embodiment includes a mobile platform having a set of wheels attached thereto. In addition, a mechanical coupling assembly is used to couple a survey instrument to the mobile platform. An adjustable position mechanism is coupled to the mechanical coupling assembly to raise and lower the survey instrument relative to the mobile platform.

Claims

1. A survey instrument conveyance comprising:

a mobile platform comprising;

a set of wheels attached to the platform;

a mechanical coupling assembly to couple a survey instrument to the mobile platform; and

an adjustable position mechanism coupled to the mechanical coupling assembly to raise and lower the survey instrument relative to the mobile platform.

2. The survey instrument conveyance of claim 1 wherein the survey instrument comprises:

an object having a point of interest located thereon;

a first navigation satellite system (NSS) antenna mounted in a first location on the object;

a second NSS antenna mounted in a second location on the object, wherein the point of interest, the first antenna, and the second antenna have a known coaxial spatial relationship;

a NSS receiver coupled to the first antenna and to the second antenna, and configured to generate location information for each antenna; and

a spatial relationship determiner to receive the location of each antenna, and determine the spatial location of the point on the object based on the known spatial relationship between the first antenna, the second antenna, and the point of interest.

3. The survey instrument conveyance of claim 1 further comprising:

a remote control device for controlling the motion of the mobile platform and remotely raising and lowering the survey instrument.

4. The survey instrument conveyance of claim 3 wherein the remote control device is a handheld mobile device selected from the group consisting of:

a tablet computer, a mobile phone, a Personal Digital Assistant (PDA) and a handheld remote control.

5. The survey instrument conveyance of claim 1 further comprising:

a drive motor mounted on the mobile platform and configured to provide power to drive the wheels of the survey instrument conveyance.

6. The survey instrument conveyance of claim 5 further wherein the drive motor is a combustion motor.

7. The survey instrument conveyance of claim 5 further comprising:

a battery mounted to the mobile platform, the battery providing power to an electric drive motor to drive the wheels of the survey instrument conveyance.

8. A mobile position determination system, comprising:

a mobile platform comprising a set of wheels attached thereto;

a survey instrument comprising;

an object having a point of interest located thereon;

a first navigation satellite system (NSS) antenna mounted in a first location on the object;

a second NSS antenna mounted in a second location on the object, wherein the point of interest, the first antenna, and the second antenna have a known coaxial spatial relationship;

a NSS receiver coupled to the first antenna and to the second antenna, and configured to generate location information for each antenna; and

a spatial relationship determiner to receive the location of each antenna, and determine the spatial location of the point on the object based on the known spatial relationship between the first antenna, the second antenna, and the point of interest;

a mechanical coupling assembly to couple the survey instrument to the mobile platform; and

an adjustable position mechanism coupled to the mechanical coupling assembly to raise and lower the survey instrument relative to the mobile platform.

9. The mobile position determination system of claim 8 further comprising:

a handle having a switch thereon, the switch activates the adjustable position mechanism to raise or lower the survey instrument to control the motion of the mobile platform.

10. The mobile position determination system of claim 8 further comprising:

a remote control device for controlling the motion of the mobile platform and remotely raising and lowering the survey instrument.

11. The mobile position determination system of claim 8 further comprising:

a drive motor mounted on the mobile platform and configured to provide power to drive the wheels of the survey instrument conveyance.

12. The mobile position determination system of claim 11 further comprising:

a battery mounted to the mobile platform, the battery providing power to an electric drive motor to drive the wheels of the survey instrument conveyance.

13. The mobile position determination system of claim 8 further comprising:

a pressure plate at the distal end of the object to trigger the generation of the first location information and the second location information.

14. The mobile position determination system of claim 8 further comprising:

fixedly coupling the first NSS antenna and the second NSS antenna to the object during manufacture, such that the spatial relationship is non-adjustable.

15. The mobile position determination system of claim 8 further comprising:

a single NSS receiver coupled with both the first NSS antenna and the second NSS antenna to determine the location of the first NSS antenna and the second NSS antenna.

16. The mobile position determination system of claim 8 further comprising:

an object tilt determiner;

an alerting device for providing an alert if the object is tilted further than a pre-defined tilt angle;

a user override to force a measurement to be performed if the tilt is outside of the pre-defined tilt angle; and

a data flag to indicate the measurement was taken during the user override while the object was outside of the pre-defined tilt angle.

17. A method for performing a survey with a dual coaxial NSS receiver mobile survey system, the method comprising:

providing a dual coaxial NSS receiver system on a mobile platform, the dual coaxial NSS receiver system comprising;

a first NSS device and a second NSS device mounted on a pole; and

a known point on the pole indicating the location of a measurement;

providing an adjustable position mechanism coupling the mobile platform to the dual coaxial NSS receiver system, the adjustable position mechanism raising and lowering the survey instrument relative to the mobile platform;

utilizing a NSS receiver coupled to first NSS device and to first NSS device, the NSS receiver configured to generate location information for each NSS device;

determining a spatial relationship between each antenna and the known point, and determining the spatial location of the known point based on the known spatial relationship between the first antenna, the second antenna, and the known point;

outputting the spatial location information in a user accessible format.

18. The method of claim 17 further comprising:

utilizing a remote control device to control the motion of the mobile platform and raise and lower the survey instrument.

19. The method of claim 17 further comprising:

utilizing a pressure plate at the distal end of the object to trigger the generation of the location information and the second location information.

20. The method of claim 17 further comprising:

determining a tilt of the object; and

providing an alert if the object is tilted further than a pre-defined tilt angle.

21. The method of claim 17 further comprising:

stopping a measurement from being performed if the tilt is outside of the pre-defined tilt angle;

providing a user override such that a measurement will be performed if the tilt is outside of the pre-defined tilt angle; and

marking the data to show that the measurement was taken during the user override while the object was outside of the pre-defined tilt angle.
