[aprssig] 2010/04/10 Balloon Tracks

[Lynn W. Deffenbaugh (Mr)]

I've generated APRS usage plots for today's flotilla of balloons across 
America.  You can find them at:  (Remember to zoom in for details)

Plots are provided for:

KE5LWQ-11, KE5LWQ-13
KG4WSV-11
WB8ELK-10, WB8ELK-11
UAH-1, UAH-2, UAH-3, UAH-4
AE0SS-11
W1WSU-11, W1WSU-13
KD0JUZ

Note that these plots were generated from APRS-IS data.  This means that 
only the first station to gate to the Internet is included.  A single 
packet at extreme range probably means that many more packets were heard 
that far out, it's just that the ones that show were heard first at that 
range.

Also, if you look at the D plots (extreme zoom showing primarily the 
originating position), any point with more than 1 red line leading from 
it was gated multiple times probably with a significant delay between 
the first and second (and sometimes third) gating.
