Embodiment 1

[0047] Such as figure 1 It shows a three-dimensional space direction angle measurement device that uses the position of celestial bodies as a standard for calibration. It is a three-dimensional space direction angle measurement device that uses the space positions of stars and planetary bodies as a measurement standard. The device uses stars and planets and other celestial bodies The position is used as the calibration and correction reference of the measurement, and the device is composed of a celestial body sensor 1, an optical telescope 2, an azimuth and pitch shaft frame 3, a plurality of sensors 4, a controller 5 and a base 6, wherein:

[0048] The azimuth and pitch shaft frame 3 includes a pitch shaft frame 31 and an azimuth shaft frame 32, and the pitch axis of the pitch shaft frame 31 and the azimuth axis of the azimuth shaft frame 32 are arranged orthogonally to each other; one end of the azimuth shaft frame 32 is placed in the base; The other end of the pedestal 32 i...

Embodiment 2

[0099] The three-dimensional space direction angle measuring device can simplify the composition of the device of the present invention, that is, the device of the present invention can be simplified into the form of a measurement component when the detected equipment already has a pitch axis, azimuth axis and axis position detection device. Direction angle measuring assembly 8 is only made up of celestial body sensor 1, controller 5 and GPS positioning module 44 etc. (referring to Figure 5 and Figure 8 ).

[0100] Only the celestial body sensor 1, the controller 5 and the GPS positioning module 44 form the azimuth measurement assembly, which is used to detect the azimuth angle in three-dimensional space for the monitored equipment that already has a pitch axis, azimuth axis and axis position detection display unit, At this time, the measurement assembly 8 is directly installed above the lens barrel of the optical telescope 2 on the pitch axis of the monitored equipment or ...

Embodiment 3

[0104] If the monitored equipment is a parabolic dish-shaped microwave antenna, at one end of the pitch axis of the parabolic dish-shaped microwave antenna, a three-dimensional space direction angle measurement assembly 8 can be used, and at one end of the pitch axis of the parabolic dish-shaped microwave antenna, the direction angle measurement assembly The conical shaft head with conical mating surface of 8 is inserted into the conical hole of the pitch shaft end, so that the matching conical surface A of the conical shaft head of the azimuth measurement component 8 and the conical hole of the pitch shaft end After installation, use clamp rings and screws to fasten them, or connect one side of the transition curve bracket 82 to an axis end of the pitch axis, and then fix the astrosensor 1 on the transition curve bracket 82 (see Figure 6 ). After installation, the pointing angle accuracy of the microwave antenna can be calibrated by using the position information of the cele...

Abstract

The invention discloses a three-dimensional direction angle measuring device and method using celestial body position as alignment calibration reference. The device is composed of a celestial body sensor, an optical telescope, an azimuth pitch axis frame, a plurality of sensors, a controller and a base. The optical telescope is arranged on the pitch axis of the azimuth pitch axis frame; the celestial body sensor is installed above the lens cone of the optical telescope or on the spindle nose of the pitch axis; and the principal optic axis of the celestial body sensor is parallel to that of the lens cone of the optical telescope. Because the celestial body sensor can sense the positions of fixed stars and planets in the sky, the positions of fixed stars and planets can be used as the calibration reference for spatial measurement to provide three-dimensional high precision angle of direction, so as to further improve the accuracy of the space angle of direction of three-dimensional directional instrument. At the same time, high precision directing of horizontal reference surface, tilt datum plane, due east, due south, due west, due north and vertical direction, and the accuracy of the angle of direction reaches the level of arc second even sub arc second.

Description

technical field [0001] The invention relates to the field of astronomical technology and measurement technology, in particular to a high-precision three-dimensional space direction angle measurement device using the positions of celestial bodies such as stars and planets as measurement and calibration references. Background technique [0002] Pointing and direction finding technology has existed in ancient times. As one of the four great inventions in ancient my country, the compass uses the physical characteristics of geomagnetism to indicate the direction of true north and south, and guide people to find the direction of travel, especially when it is used for navigation. , can make the ship not lose its way in the vast sea. In the future, some people also used telescopes to observe Polaris to determine the true north. However, the above two azimuth measuring instruments can only indicate the azimuth pointing angle on a two-dimensional plane, and the azimuth angle indicatio...
