6 Verify the following GPS information (shown above in underlined text):
– At least 4 satellites are tracked, and 4 satellites are visible.
– GPS Receiver Control Task State is “tracking satellites”. Do not continue until this occurs!
– Dilution of Precision indication is not more that 30.
Record the current position base site latitude, longitude, height and height reference (height reference
to Mean Sea Level (MSL) or GPS height (GPS). (GPS = 0 MSL = 1).
