Survey Wheels
All of GSSI’s antennas are designed to operate with survey wheels. Some antennas have built-in survey
wheels, including the 62000 Palm Antenna, the Mini-SIR and the MINIXT. The series of concrete
antennas, including the 5100, 5101 and 52600, have survey wheels built in to their special carts, the 614
and 615. The larger antennas, including the 3101D, 5103, 50400 and 5104 are used in the larger carts, the
623, 643 and 653, which have survey wheels built in to them. Various sizes of survey wheels can also be
attached directly to these antennas. This includes the 611, 620 and 622. For highway surveys we use the
630 Distance measuring Instrument (DMI).
