Abstract

A method and device for quickly capturing the initial orientation of a rocket prism are used to determine the initial orientation of the rocket prism and the aiming point of the aiming device. The method includes the steps of setting an optical telescope, aiming at a target, and determining the initial orientation and aiming point. The device includes an optical telescope, a target body and a record marking mechanism, the optical telescope and the target body are respectively connected with the record mark mechanism, the target body is provided with a characteristic symbol and the target body can be placed on the record Move within the area defined by the marking mechanism, the recording and marking mechanism is used to record the vertical projection point of the target body position when the optical telescope is aimed at the characteristic symbol, and mark the vertical projection point and the center of the optical telescope A position vertical projection point is used to determine the aiming point and the initial orientation.

Description

technical field [0001] The invention relates to an aiming technology, in particular to a method and a device for quickly capturing the initial orientation of a rocket prism for solving the problem of quickly determining the initial orientation of a launch vehicle based on a strapdown inertial group. Background technique [0002] The launch pads of active launch vehicles (such as CZ-2F and CZ-3A series) can rotate, and at the same time use inertial platforms for navigation, and the inertial platforms can be precisely leveled after being powered on. The ground aiming adopts the method of long-distance oblique aiming, that is, in the ground aiming room about 130m away from the rocket, two aiming points P1 and P2 are built, and two sets of ground aiming equipment (primary and auxiliary) are set up on the aiming points (the collimator is set up on the guide rail). ), set up the benchmarking instrument on the reference point P3 and the inspection point P4, the launch point P4 is t...
