Publikováno v: Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019).

Surveys of potential sites for GNSS ground reference sensor stations play a fundamental role for assessing the multipath and RF interference environments of the candidate locations. The outcomes of such surveys can be either used for site acceptance,
