Example Embodiment

[0083] In order to make the purpose, advantages and characteristics of the present invention clearer, a kind of self-positioning system and method based on the vehicle-mounted theodolite that the present invention proposes below in conjunction with accompanying drawing and specific embodiment. 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.

[0084] The positioning and orientation technology based on the Global Positioning System (GPS) is widely used. As we all know, GPS has the characteristics of continu...

Abstract

The invention discloses a self-positioning system and method based on a vehicle-mounted theodolite, thereby solving problems of complex operation process, large calculated amount, large measurement error and poor maneuverability when the existing theodolite performs positioning measurement in a landing mode. The system comprises a vehicle-mounted theodolite, two BD/GPS receivers and an upper computer; 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; two BD/GPS receivers receive electromagnetic waves of BDand/or GPS satellites; and coordinate positions of the BD and/or GPS satellites are calculated through an upper computer, so that position coordinates of the vehicle-mounted theodolite are obtained.

Description

technical field [0001] The invention belongs to the technical field of equipment positioning and orientation, and specifically relates to a self-positioning 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 vehicle-mounted th...
