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,

Normally operations are restricted to daylight only, but because bad weather was forecasted for the days to come we've received an exemption and were allowed to depart during dark hours. Cargo operations were running close to the departure deadline so we quickly secured the cargo and prepared the vessel for sea.
