Position and azimuth measurement device and surveying device
First Claim
1. A position and azimuth measurement device comprising:
- a GNSS device, including a GNSS antenna, configured to obtain position information of the GNSS antenna on the basis of observation values from satellites;
a horizontal rotating section capable of rotating the GNSS antenna horizontally, wherein the GNSS antenna is provided at a known distance from a vertical axial center of the horizontal rotating section;
a leveling section capable of leveling the horizontal rotating section;
a horizontal angle detector configured to detect a horizontal angle of the horizontal rotating section; and
a control device,wherein the control device causes the GNSS device to continuously obtain the position information while causing the horizontal rotating section leveled by the leveling section to make one full rotation, and is configured to compute geographical coordinates and an azimuth angle on the basis of the position information obtained throughout the full rotation,wherein of the satellites from which the GNSS device obtains the observation values, the control device selects only satellites capable of outputting observation values throughout the full rotation, andwherein the control device is configured to create a shape filter having a ring shape and a predetermined width with respect to a circle having a radius equivalent to a distance between the vertical axial center and the GNSS antenna, and match the shape filter to a position in which the number of pieces of the position information located within the shape filter is highest.

Abstract
A position and azimuth measurement device capable of measuring geographical coordinates and azimuth angles and a surveying device are provided. The position and azimuth measurement device includes a GNSS device, having a GNSS antenna for obtaining position information thereof; a horizontal rotating section capable of rotating the GNSS antenna horizontally; a leveling section capable of leveling the horizontal rotating section; a horizontal angle detector configured to detect a horizontal angle of the horizontal rotating section; and a control device. The control device causes the GNSS device to continuously obtain the position information while causing the horizontal rotating section leveled by the leveling section to make one full rotation, and computes geographical coordinates and an azimuth angle on the basis of the position information obtained throughout the full rotation.
