Most GPS devices I've used provide a precision estimate already.

Most GPS devices I've used provide a precision estimate already.
- mikeash 11y agoHow accurate is that precision estimate, though? Is it built with enough care that you can put lives on the line?
- hueving 11y agoAppeal to fear isn't an argument. Either the precision is right or it isn't. Precision requirements aren't unique to aviation and aviation doesn't even have the strictest requirements. The required precision of surveying equipment is much higher than what aviation needs. I would have much more faith in an open source project with lots of people independently verifying the precision of calculations for known devices than closed source stuff from aviation companies that hide behind fear rather than real justifications for the price.
