HI (Height of Instrument) Measurement Tape
The HI measurement tape, Figure 1.7, is used to measure height of the GPS antenna over the
survey point. The end of the tape hooks onto the antenna. The tape is extended until the spike
on the tape case is on the point. Then the height of the antenna is noted on the tape.
Field Bag
The field bag, Figure 1.8, is used to transport the components of each ProMark2 GPS receiver
system between the office and the field.
