[aprssig] The best resolution of position from APRS

[Andrew Rich]

I did an experiment, using google earth and placed two points.

Decimal degrees

-27.574114?
153.103612?

and 

-27.574118? (+0.000004)
153.103612?

Degrees Minutes Seconds

 27?34'26.81"S
153? 6'13.00"E

and 

 27?34'26.82"S 
153? 6'13.00"E

And this gave me roughly these results:-

When using the google earth measure function, it returned roughly 40cm.
