What’s new: A discussion of the importance of GPS/GNSS to maritime – especially in ports.  This is the first discussion of its type we have seen.

Why it’s important:

  • Safety: Ship size, channel width, channel depth, bridges and other obstructions make precise electronic navigation critical in ports, because often the pilot and captain can’t see all they need to see. 
  • Make More Money: With resilient electronic navigation ports could better operate in night and reduced visibility conditions increasing through put and efficiency.

What else to know: Matt Shirley is the primary author and an experienced port/harbor pilot.
