GNSS has become one of the most widespread 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 widespread 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.
