Embodiment Construction

[0094] In order to make the purpose, advantages and features of the present invention clearer, a kind of self-positioning and orientation system and method based on the vehicle-mounted theodolite proposed by the present invention will be provided below in conjunction with the accompanying drawings and specific embodiments. For further details. The advantages and features of the present invention will become clearer from the following description. It should be noted that: the drawings are all in a very simplified form and use inaccurate proportions, which are only used to facilitate and clearly illustrate the purpose of the embodiments of the present invention; secondly, the structures shown in the drawings are often actual structures part; again, each drawing needs to display different emphasis points, and sometimes adopts different scales.

[0095] The positioning and orientation technology based on the Global Positioning System (GPS) is widely used. As we all know, GPS has ...

Abstract

The invention discloses a self-positioning orientation system and method based on a vehicle-mounted theodolite, thereby solving problems that when the existing theodolite carries out positioning orientation measurement in a landing mode, the operation process is complex, the calculated amount is large, the measurement error is large, and maneuverability is poor. The system comprises two same positioning devices and an upper computer. Each positioning device comprises a vehicle-mounted theodolite and two BD/GPS receivers; the two BD/GPS receivers are arranged on the two top surfaces of the opening side of a U-shaped bracket of the vehicle-mounted theodolite; the two BD/GPS receivers receive electromagnetic waves of a BD satellite and/or a GPS satellite, the coordinate positions of the BD satellite and/or the GPS satellite are calculated through the upper computer, so that position coordinates of the vehicle-mounted theodolite are obtained; and the azimuth angle and the pitch angle of any target can be obtained through the two vehicle-mounted theodolites.

Description

technical field [0001] The invention belongs to the technical field of equipment positioning and orientation, and specifically relates to a self-positioning and orientation system and method based on a vehicle-mounted theodolite. Background technique [0002] The photoelectric theodolite is a photoelectric telescope used for precise angle measurement, which integrates tracking, ballistic measurement, and target attitude measurement. It is an important optical measurement equipment in the shooting range. The photoelectric theodolite can provide accurate ballistic data for the development department of missiles and launch vehicles, provide an important basis for the accuracy analysis, evaluation and performance improvement of type tests, and play an important role in related experiments. [0003] The existing vehicle-mounted theodolite adopts the method of landing to carry out positioning and orientation measurement to the target. Before use, firstly, the position where the ve...
