Description

technical field

[0001] The invention belongs to the field of engineering surveying, and in particular relates to a long-distance high-precision elevation transmission aiming target plate. Background technique

[0002] "National First and Second Class Level Surveying Specifications" (GB / T12897-2006) only stipulates the relevant requirements for the production of sight marks for cross-river leveling surveys below 3.5Km. In some large-scale projects, some ultra-long-distance cross-river ( Sea) leveling can be carried out using the GPS leveling method, but in some projects due to topography and other conditions, the GPS leveling method cannot be implemented according to the specifications, and the accuracy and reliability are difficult to guarantee. ) remains irreplaceable. However, the current aiming marks used for long-distance high-precision elevation transmission are limited by field observation conditions, and cannot meet the observation requirements of day and night at th...
