Terrain type should be included. I'm thinking we need a wiki page. Does 
one already exist? It should have a column for terrain.

How to avoid being tricked by "lucky satellite positions"? I guess one 
way would be to run the test multiple times. How many times? How long 
apart? Perhaps, as you did, twice, one day apart?
