Fixed-Height GPS Tripod
An option to the tripod, tribrach, and tribrach adapter combination is the fixed-height GPS
tripod, Figure 1.15. The fixed-height GPS tripod has the advantage of eliminating the
possibility of measuring and/or recording an incorrect HI, since the height is fixed. HI
blunders are one of the most common mistakes during data collection.
Note: the vertical antenna extension is 3 inches (0.0762 m).
