The US Navigation Center posted a notice alerting users of the Global Positioning System that there is possibility of a short period with high Horizontal Dilution of Precision (HDOP) / Position Dilution of Precision (PDOP) in certain locations, because of satellite maintenance.
Navigation relies heavily to the Global Positioning System. This is because it is easy to use, accurate and reliable. However, GPS signals can be compromised by both natural and human sources. If that happens it can lead to inaccurate data or complete loss of GPS signal, North P&I Club informs.
Ship navigation in polar seas takes additional knowledge beyond that needed in less challenging navigation environments. It requires long experience working on specialized vessels in ice conditions, which goes with special training.
Both heavy weather and tropical storms demand of crew’s preparation and immediate response, in order to ensure vessel’s safe passage with no or less harms on vessel’s cargo or even vessel’s personnel.
The essence of ship navigation in ocean waters and the role of navigational tools in ensuring a safe sail at the sea explained! The seventh article in our Bridge Procedure Series.

The US Coast Pilot publications already include the Coast Guard’s Vessel Traffic Service regulations.
BMT aims to address the challenge of how traditional manned vessels can co-exist with autonomous systems in shared water space. Deimos Space UK will investigate how the exploitation of existing and future satellite capabilities can contribute to this objective.
The US Coast Guard says that the Arctic Navigational Safety Information System is currently under development, seeking to offer a reliable means of providing critical navigational safety information such as hazards, chart corrections and weather to Arctic mariners via digital means.
The new office opened on 2nd October in Piraeus and is expected to offer technical advice on owners seeking communications, navigation and other technical solutions for their vessels.
