Combination measurement method for high precision position, azimuth angle and pitch angle, and device thereof

Abstract

The invention discloses a combination measurement method for high precision position, azimuth angle and pitch angle, and a device thereof; a measurement basic line consists of measurement marking points where two satellite receiving antennas are arranged; a dual-system satellite positioning receiver plate and a beacon receiver plate synchronously receive the signals of a first satellite antenna and a beacon antenna; the dual-system satellite positioning receiver plate synchronously receives the digital signals of the beacon receiver; a GPS receiver plate synchronously receives the signals of a second satellite antenna; the first and second satellite antenna signals and beacon signals are synchronously calculated so as to precisely measure the three-dimensional position where the satellite antenna is arranged and measure the azimuth angle and pitch angle of the antenna basic line under geographic coordinates. The method and the device integrate the dual-system satellite positioning, GPS, beacon receiver plate and computer; the device is provided with a liquid crystal display screen, two satellites and a beacon receiving antenna outside the box, ensures the positioning precision more than 8 meters, receives beacon differential signals at coastal areas, leads the precision to be more than 1 meter and has the directional precision more than 0.1DEG under the basic line of 3 meters.

Description

technical field [0001] The invention belongs to the technical field of positioning and orientation, and relates to a combined measurement device for high-precision position, azimuth and pitch angle. Background technique [0002] With the development of the national economy and transportation, positioning and orientation technology has shown a prominent and important position, especially in the weapon system, it is an important component, and it is the main equipment to improve the shooting accuracy, quick response ability and maneuverability of self-propelled artillery. Quickly provide accurate position and reference direction for self-propelled artillery, command vehicles, forward-looking reconnaissance vehicles, reconnaissance branch-firing radars, weather radars, etc., and enable self-propelled artillery to automatically reset round by round during firing. [0003] In order to truly save oneself effectively in future wars and at the same time strike the enemy accurately, ...
