THE STUDY OF KINEMATIC GNSS SURVEYING FOR BIM GEOREFERENCING

Abstract

Building Information Modeling is a tool for creating, presenting and managing building data. The use of BIM has the advantage of obtaining greater detail and fidelity in design, construction and operation, increases efficiency, and serves as a digital transformation of the construction industry. As BIM continues to evolve and integrate, needs accurate spatial georeferencing is needed as a way to correctly display a model without changing the underlying data. The great common tool for referencing is GNSS. Having in mind tight surveying conditions for urban territories. It is preferable to use kinematic surveying mode. This study is an analysis of field measurements aimed at investigating the problem of GNSS accuracy under various adverse operating conditions. Every year, new updated receiver models and software versions appear on the geodetic market, so it is necessary to study their effectiveness and given accuracy. This paper shows information about a kinematic survey performed in a canopy, multipath and in an open area to evaluate the performance of the user segment of various manufactures.
