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.

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

How AIS Works - Operation of AIS

Maritime pilots work in an irregular deployment system (rotation system) with unpredictable work assignments under high levels of physical and mental stress. Fatigue or chronic diseases, e.g. coronary heart disease, peptic ulcers or gastritis can occur as a consequence.

Ships don't exactly have brakes. Lou Vest, a retired Houston ship channel pilot tells us about a close encounter between a ship and a barge.

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...

By the end of this year, our sea pilots are set to have undertaken a record number of pilotage acts. The total number is set to exceed 10,700, with almost 99% of the acts completed without delay.

This video was kindly provided by a friend of Pilot Captain Haitham Alzahrani, Saudi Arabia. Pilot Ladder Check: non-compliant, no retrieval line Editor's note: A backpack on the back in combination with a lifejacket is usually not a good idea. There are only a few lifejackets that unfold in the water without any problems even with a backpack!
