[time-nuts] TBolt self survey

[Stan, W1LE]

Hello Arnold,

Thanks for that pointer, the height calculator works out nicely.

for my location I estimated height above mean sea level as
235' (ground level) + 10' (height of the tripod and mast to the GPS puck 
antenna)
or an estimate of 245' ASL.

The calculator shows:

Your Input Coordinates and GPS Height:

Latitude = 41.72877° N = 41° 43' 43.57" N
Longitude = 70.4642° W = 70° 27' 51.12" W
GPS ellipsoidal height = 47.915 (meters)
Geoid height = -29.190 (meters)
Orthometric height (height above mean sea level) = 77.105 (meters)
(note: orthometric Height = GPS ellipsoidal height - geoid height)


77.105 meters = 252.969'

As a (microwave) ham, I will always take the extra height.
