In the boresight process of each system, the attitude of the airplane needs to be horizontally adjusted. When the horizontal state of the airplane is adjusted, the handheld horizontal measuring scale is placed at each measuring position given by a designer to establish a reference coordinate system, the theodolite is used for observing the relative altitude difference of each point at the same height to judge whether the airplane posture is in the horizontal position, and the boresight is performed in the state, so that the adjustment of the horizontal posture plays an important role in measuring boresight data. According to the operation method of the existing horizontal measuring scale, the verticality of the horizontal measuring scale needs to be ensured manually. Meanwhile, when the theodolite is used for reading, due to the fact that deviation is easily caused by the influence of factors such as sight lines, placing positions and the like, the adjustment of the horizontal posture is influenced, and further the measurement of the calibration target data is influenced.
Based on the reasons, the horizontal measuring scale for adjusting the horizontal attitude of the airplane improves the stability in the measuring process by adding the fixed base, reduces the working intensity of operators, increases the laser transmitter installation part to replace the reading of a theodolite, improves the accuracy of the horizontal attitude adjustment and improves the working efficiency.
