Right now we often lose satellite communications during periods of heavy rain, fog, cloud cover, snow, etc. As all of the new navigation systems are based on GPS technology & this link to the satellites is still the weak link. Having shore based relay cell towers is also subject to weather conditions. In vehicles now using adaptive cruise control and lane change warning technologies they suffer from rain, snow and fog signal loss. This scares me when people talk about driverless vehicles. Lose the signal the the vehicle loses control, killing people.
When an accident happens now we go to great lengths to find the cause, sometimes even laying blame on humans and issuing fines and other forms of punishment. The future will have us
blaming software and hardware developers I guess.
Big picture, GPS should be secondary to other means such as an accurate gyro. Can't hack the gyro. Even in the instance of "phoning home", that defeats the purpose of autonomy. Going back to the previous statements about autonomous helicopters... It lost comms, knew where it was and where it needed to go and could act accordingly. Having a person per craft to monitor wouldn't even be completely necessary.
Playing devils advocate... Let's say a ship comes to a scenario it doesn't know. Let's say GPS is out, gyro is down, navigation beacons are dead. It'd still be cheaper to get a pilot (or something along that idea) to the ship.
