THE EFFECT OF SURVEYING ANGLE SYSTEM AND ITS RELIABILITY ON MEASURING ACCURACY OF GJ-341 SMALL REMOTE-CONTROL OPTICAL-ELECTRONIC THEODOLITE

测角系统的精度及其可靠性直接影响光电经纬仪的测量精度。GJ- 341小型遥控光电经纬仪的测角系统采用 19位增量式编码器 ,理论上达到了要求。但由于测角系统及其可靠性存在诸多问题 ,使其在实际使用中无法满足 GJ- 341小型遥控光电经纬仪测角精度的要求。本文分析测角系统及其可靠性对 GJ-

The surveying angle system and its reliability has great effect on the measuring accuracy of optical electronic theodolite.19 figure incremental mode optical shaft angle encoder is used in GJ 341 small remote control optical electronic theodolite.Its accuracy is enough in terms of theory.But there are some problems in the surveying angle system and its reliability.This made its accuracy is not enough for GJ 341 small remote control optical electronic theodolite in practice.In this paper,the effect of the surveying angle system and its reliability on the measuring accuracy of GJ 341 small remote control optical electronic theodolite is analyzed.
