I've just spent (wasted?) an hour looking for a way to adjust my position as reported in/by/on
APRS, as reported by CWOP. The "registered" location is about 10 feet from the actual location in my yard. The
APRS position is ~0.1 miles ESE, on the green of the golf course south of me.
I registered my location on 4/17/15 and modified it three days later making moving it 0.0001?N and -0.0002?W. I had five different altitude numbers from various sites averaging to 354.66 feet (108.1 meters).
First WC data was: 35? 04'.13N, 89? 44'.10W, 108 metres.
I changed that to: 35? 04'.13N, 89? 44'.1
1W, 108
.1 metres.
I have a two "thumbs up" CWOP rating with the following "error" message:
Average barometer error: -0.5 milliBars
Error standard deviation: 0.6 milliBars
TwoThree questions:
- Where did APRS get its location info?
- Will a tenth of a meter/metre really make a difference in the baro pressure?!
- Should I care?
