Abstract
GNSS has become one of the most wide-spread measurement technologies, allowing cm-level positioning accuracy using RTK or Network RTK. Unfortunately, the system's major drawbacks are the requirement for a clear view of the sky and accuracy dependent on the geometric distribution of the satellites, not only varying throughout the day but also prone to location specific problems. With wide-spread utilisation of GNSS for monitoring of manmade structures and other civil engineering tasks, such shortcomings can be critical.
One of possible solution is the deployment of a supporting system, such as Locata – a terrestrial positioning technology, which mitigates the need for a clear view of the sky and provides system integrity control.
This paper, part of the proposed integration feasibility study, presents Locata performance indoors, its capacity and mitigation methods.
