A method of visibility analysis using a visibility analysis tool for selection of reference station site

摘要

The present invention relates to a visibility analysis method for selecting a satellite navigation system reference station using a visibility analyzer for analyzing and selecting visibility through a portable terminal unit and a visibility analyzer, , Visibility analysis software, and a visibility analyzer capable of photographing with a camera and capable of horizontally and non-rotatably rotating the terminal section capable of detecting latitude, longitude, altitude, angle and position is installed in a candidate site Adjusting a horizontal position; When the visibility analyzer is installed at a position where the reference station is to be installed and the level is adjusted through the step of checking the visibility of the visibility analyzer, ; Confirming the visibility of the elevation angle of 0 ° through the step of confirming the visibility of the elevation angle of 0 °, checking the visibility of the elevation angle or elevation angle of 5 ° through the terminal unit, And confirming and analyzing an obstacle existing at an elevation angle or an elevation angle of 5 degrees or more through the terminal unit when the visibility of the elevation angle of 5 degrees is confirmed through the terminal unit through the step of confirming the visibility, do.
