[time-nuts] GPS Horizon Plots

[Peter Putnam]

Greetings,

GPS horizon information I have collected during recent travels might
be of interest to those siting an antenna for time-keeping purposes.

It shows that obstacles to the north of a station in the northern
hemisphere are not necessarily detrimental to GPS reception. The
opposite is true in the southern hemisphere.

If you live north of 60°N (or south of 60°S), other considerations apply.
