As AMSA reported in the past, due to the increased accuracy of GPS and introduction of other global positioning constellations, like GLONASS, GALILEO and Beidou, its Differential Global Positioning System (DGPS) service is no longer needed. As a result, AMSA will discontinue DGPS system from the following summer, specifically on 1st July 2020.
The USCG’s Office of Navigation Systems (CG-NAV), officially announced its approval for a series of Automatic Identification System Private Aids to Navigation (AIS PATON), in order to set restricted navigation zones, near commercial rockets’ launch.
The United States Maritime Administration (MARAD) issued the US Maritime Advisory No. 2019-005 regarding Global Positioning System (GPS) interference in the Eastern Mediterranean Sea and Red Sea. Therefore, the Republic of the Marshall Islands Maritime Administrator urges all RMI-flagged vessels transiting the designated areas listed in the below Advisory to exercise caution.
UK Hydrographic Office uses crowdsourced information from seafarers who report navigational challenges and other sightings through submitting a Hydrographic Note paper or through the H-Note App. Hydrographic note is usually submitted through a form of fax or filling a form and sending it via email . Yet, the application enhances the navigational safety since connectivity helps with passing fast information. The application allows the cooperation with the campera of the smartphone or its GPS for a better gathering of location information.
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.
