A case of GNSS positioning performance deterioration and its effects on maritime navigation

Satellite navigation positioning performance should not be considered in absolute terms, but rather matched with the requirements for GNSS- based applications. Here, we present a study of the positioning performance of a commercial- grade single-frequency un-aided GPS receiver for maritime navigation applications in the period of moderate space weather disturbances. Matching the GPS positioning performance results with the maritime navigation applications requirements, we found that the category of GNSS receivers concerned does not meet the requirements of the high-quality maritime navigation applications. We presented and discussed the potential shortcomings caused by such situations and proposed the recommendations that will allow for utilisation of GNSS receivers in high-quality and critical marine navigation applications.
