How does GPS work?

Of course, as a Nautical Specialist, I also deal with the international discussion on the advantages and disadvantages of satellite-based navigation, e-navigation and conventional terrestrial and astronomical navigation.

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

In the spring of 2023, the IMO Sub-commission on Navigation, Communications and Search and Rescue (NCSR) may start a process of review and amendments to the SOLAS Ch V. reg 23

“Marine Pilotage – The Arabic book" by Ahmed Sati, Marine Pilot at P&O Maritime, is the first of its kind in Arabic language and specifically concerned with maritime pilotage, it is a reference book and introduction to the basics of the Marine Pilot's work for Arabic readers who are willing to take the challenge and join the force of Pilotage and to act as a refresher to the experienced Pilots who are practicing Pilotage in local or foreign organizations.

OHB Digital Solutions GmbH develops systems for monitoring the GNSS frequency bands as well as detection, classification and localization of intentional or unintentional interference sources. Many stakeholders and applications as well as critical infrastructure providers are relying on GNSS to provide their services. Since Global Navigation Satellite Systems (GNSS) are widely used in safety and value critical applications, GIDAS detects, classifies and localizes any GNSS interference...

Report by nC2 Engineering Consultancy at the University of Southampton on behalf of the International Maritime Pilots' Association (IMPA) to investigate the effectiveness and impact of different methods of securing pilot ladders in medium lengths in a laboratory-based project.

This webinar is part of the Resilient Positioning Navigation and Timing Seminar Series.

Using two, 66TBP tugs to assist in berthing the 90,000 GT bulker “Jin Weng Feng”. The port is “Puerto Brisas” at La Guajira, Colombia. The vessel is turned to port just outside the berth limits due to limited room in the basin with enough depth. Then she’s backed in.

I am not a computer savvy. My knowledge in programming and robotics and those sort of things is nil. I get lost in the sea of social media and easily entangle myself in the web. All I have done for the last 25 years or so is to pilot ships through the Panama Canal. However, during the last couple of years I have done my best to catch up with technology, since it has enhanced our possibilities and improved safety in our field. But still, I have to admit that I am way behind the new guys in this important issue.
