Embodiment Construction

[0018] A directional theodolite based on satellite orientation, comprising: a theodolite component, a tripod A12 and a tripod B18, and also includes: a target component, a main antenna 10, a secondary antenna 17, a receiver 11, an internal cable 20 and a communication cable 19. Wherein, the theodolite components include: a base 1, a telescope 2, a U-shaped bracket 3, a horizontal axis 4, a vertical axis 5, a level A6, an electronic display 7, an optical plummet A8, and an antenna installation base 9 . The target components include: a reticle 13 , a level B14 , an optical plummet B15 , and a metal frame 16 .

[0019] The main antenna 10 is placed on the antenna installation base surface 9 of the theodolite component and fixedly connected. The telescope 2 is placed on the horizontal axis 4 and fixedly connected. The horizontal shaft 4 is placed on the U-shaped support 3 and fixedly connected. The level A6 and the electronic display screen 7 are placed at the lower end of the ...

Abstract

The invention discloses an orienting theodolite based on satellite orientation. The orienting theodolite comprises a theodolite part, a tripod A (12), a tripod B (18), a target part, a main antenna (10), an auxiliary antenna (17), a receiver (11), an internal cable (20) and a communication cable (19). By utilizing the measures of improving the performance of satellite antennas, and improving the satellite orientation algorithms, and the like, the orientation precision with triple standard deviation reaches 50'' on a 10m base line and 10'' on a 50m base line, so that the use requirements in the fields of launching vehicle orientation, north basis establishment, railway construction and the like can be met. According to the orienting theodolite, only a set of satellite receiving parts are increased to a traditional theodolite, so that the equipment cost is far lower than that of traditional orientation equipment such as gyro theodolite with same functions of the orienting theodolite; furthermore, the orienting theodolite is high in reliability, easy to maintain and applicable to outdoor use and has relatively wide application prospects.

Description

technical field [0001] The invention relates to a theodolite, in particular to a directional theodolite based on satellite orientation. Background technique [0002] The traditional theodolite is an instrument for measuring horizontal and vertical angles, which consists of a telescope, a horizontal axis, a vertical axis, a level and a base. From the earliest vernier theodolite to the current optical theodolite and electronic theodolite, theodolite is an instrument for measuring relative angles. It can give accurate relative angles, but it cannot give the absolute azimuth between the optical axis of the theodolite and the astronomical north direction. . [0003] In recent years, with breakthroughs in high-precision measurement satellite antenna technology, satellite anti-jamming technology, and satellite orientation algorithms, and with the successful networking of the Beidou-2 satellite navigation system, the orientation accuracy based on satellite orientation is getting hi...
