Checking the optical plummet of the upper tribrach plate for adapter GNSS antennas

Abstract

The article deals with the most common variant of installing a GNSS antenna over a ground mark. The main conditions that must be observed in the adapter for GNSS antennas are listed. The article deals about the need for daily checking of the optical plummet, built into the stand of the adapter for the GNSS antenna. The known methods for checking the optical plummet are considered. The analysis of the known techniques for the possibility of their application for checking of a optical plummet mounted in upper tribrach plate is carried out. The authoring technique of checking of the optical plummet of the stand of the adapter support for GNSS antennas is described. The scheme of checking is given. The advantages of the proposed method in relation to existing methods are noted. The devices proposed by the authors for improving the accuracy and simplifying the checking process are described. The scheme of the sighting mark is given. The article describes an experiment to test the proposed method. It is presented with the results of the experiment.
