Long Range Identification and Tracking plays an important role in Maritime Domain Awareness. Countries that fall under the purview of the SOLAS convention can share the necessary marine security information along with all other required information about the ships that sail through the countries’ coastal boundaries. In this post, the Navigation Center provides information about reporting requirements.
Maritime Commons is sharing the content of U.S. Maritime Advisory 2018-014-GPS to inform our readers that significant GPS interference continues to be reported by vessels and aircraft operating in the Eastern Mediterranean Sea near Port Said, Egypt, the Suez Canal, and in the vicinity of the Republic of Cyprus.
Reports of GPS problems submitted to Navigation Center through the webpage will be posted to the GPS Problem Report Status webpage after review by NAVCEN staff. Reports will be anonymized to protect the submitter’s personal information and any equipment manufacturer data. All reports made in 2018 are now available and prior years will be available in the future.
