The smallest possible resolution of GPS in the horizontal is 10mm (6-7 digits) with local differential corrections.
In general, 4-5 digits is the precision to expect.
- jstanley 6y agoHm, then I think my calculation that the 14th digit is worth 0.15mm must be wildly incorrect. For a 40km earth circumference, I worked out 10^-14 * 360 * 4*10^7 = 0.00014 metres.
- schoen 6y agoI think you want to divide by 360 instead of multiplying by 360 - when you divide by 360, you should get the linear distance represented by one degree of latitude or longitude.
