Re: Everyone Has Screwed Up
The real answer is a pivot back to terrestrial technologies like eLoran and radio clock transmitters. The problem is persuading a bunch of politicians to agree to this and standardise on it when some of them have just spent billions on a GPS clone. Plus rolling these out to developing areas is not trivial; they’re just as dependent on GPS for comms nets, but are far less able to build their own chain of terrestrial transmitters for timing and position.
With a +/-8 metre accuracy, it is certainly fine for locating your ship in the Bristol Channel, but I'm not sure it's much good for surveying.
But remind me - is it only iPhones that have Enhanced Loran receivers built into them, or do Android phones have it as well?
