Embodiment Construction

[0036] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] Such as figure 1 , 2 As shown, a high-precision stakeout method for shooting to the datum. This method uses three astronomical geodetic control points, A, B, and C. Among them, A is the main control point, and B and C are the direction points. , the three astronomical geodetic control points are all built with mandatory centering observation piers.

[0038] Lofting method of the present invention specifically comprises the following steps:

[0039] 1) Layout of benchmark control network

[0040] Establish a permanent starting bearing edge around the equipment field;

[0041] In order to facilitate the sighting and overcome the influence of the centering error of the instrument, the length of the starting azimuth side should be 2-4 kilometers, the shortest should not be less than 100 meters, and the measure...

Abstract

The invention discloses a high precision lofting method for directive reference. The method comprises the following steps: arranging a reference control net; determining the center O of the equipment;and lofting the directive reference. The method can meet the demand on high precision and accuracy, and is short in consumed time and high in work efficiency. In the lofting process, reference can belofted precisely by means of a total station and relatively little auxiliary equipment. A lofting point is precisely projected to the ground by means of a self-dependent innovated forced centering point method, the precision can reach within 0.1 mm, and the method has huge promotional value.

Description

technical field [0001] The invention belongs to the technical field of beamline calibration measurement, in particular to a high-precision stakeout method for beamline references. Background technique [0002] Shooting calibration measurement, also known as long-range missile orientation measurement, is mainly to provide accurate launch directions for ground launch equipment such as satellites, surface-to-surface missiles, and excited missiles. First, according to the theoretical shooting value proposed by the user, stake out the position of the aiming point, and then determine the astronomical azimuth or geodetic azimuth from the aiming point to the launching point (generally calculated by astronomical azimuth), if the actual measured value and the theoretical When the difference of the shooting value is within the tolerance range, the shooting calibration is completed. Radial datum stakeout is to establish datum points and datum data for radial calibration measurement, an...
