Using crowdsourcing to enhance navigational safety

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.

GPS common problems and how to mitigate them

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.
