[amsat-bb] Proximity to grid line boundary

[Don KB2YSI]

The VUCC rules (
http://www.arrl.org/files/file/Awards/VUCC%20Rules%20April%202020.pdf)
state:

(F) Grid boundary lines and grid corners must be established using a GPS
receiver whose map datum is set to WGS84, the global default for curif nt
GPS receivers. The GPS receiver should be set to use WAAS (Wide Area
Augmentation System) if so equipped, since this improves the error figure
to as little as 5 feet. In no case may the GPS receiver show an error
figure in excess of 20 feet. Any modern GPS receiver equipped with WAAS
will easily meet this requirement, as will most older
 units without WAAS.
