Geodetic target and position determination system
First Claim
1. Geodetic target, comprising:
- an orienting device with a bearing direction;
a first inclinometer with a first axis of inclination, the first inclinometer configured to determine an inclination of the geodetic target about the first axis of inclination;
a reflector configured to reflect a first portion of a measurement beam that is generated by a source external to the geodetic target and that is incident on the reflector, the reflector configured to reflect the first portion of the measurement beam in a direction substantially towards the source;
an imaging optics configured to focus a second portion of the measurement beam that is incident on the imaging optics;
a matrix sensor, whose receiving surface is situated in an image plane of the imaging optics, the imaging optics configured to focus the second portion of the measurement beam in an image point on the matrix sensor; and
an interface, which is connected to the first inclinometer and the matrix sensor;
wherein a spatial arrangement and orientation of an axis of symmetry of the reflector relative to the bearing direction of the orienting device is predetermined;
wherein the first axis of inclination makes an angle a different from zero with an optical axis of the imaging optics;
wherein the optical axis of the imaging optics coincides with the axis of symmetry of the reflector or is parallel to it;
wherein a location of the image point on the matrix sensor is dependent on an orientation of the reflector relative to the second portion of the measurement beam; and
wherein the interface is designed to put out signals received from the first inclinometer and the matrix sensor to determine a spatial orientation of the reflector relative to a target point lying in the bearing direction.

Abstract
A geodetic target 1 for use in geodesy comprises an orienting device 10 with a bearing direction P, a first inclinometer 20 with a first axis of inclination 20A, a reflector 30 reflecting incident measurement beams S, an imaging optics 40 that focuses the incident measurement beams S, a matrix sensor 50, whose receiving surface 51 is situated in an image plane of the imaging optics 40, and an interface 60, which is connected to the first inclinometer 20 and the matrix sensor 50. The spatial arrangement and orientation of the optical axis and/or axis of symmetry 30A of the reflector 30 relative to the bearing direction P of the orienting device 10 is predetermined here. The first axis of inclination 20A makes an angle α other than zero with an optical axis 40A of the imaging optics 40. The optical axis 40A of the imaging optics 40 coincides with an optical axis 30A and/or axis of symmetry of the reflector 30 or is parallel to it or make an angle with it. The interface 60 is designed to put out the signals received from the first inclinometer 20 and the matrix sensor 50 for determining a spatial orientation of the reflector 30 reflecting the measurement beams relative to the target point Z.
Moreover, a position determining system comprising this target and a method which uses this target is disclosed.
