SWASH Buggy

The SWASH system platform is a six-wheel amphibious buggy, approximately 2.4 meters long, with a plastic body, an enclosed canvas cabin, and a cargo bed. It is Max IV manufactured by Recreatives Industries, Inc. of Buffalo, New York. Mounted on a custom frame are four GPS antennas, constituting the Magellen/Ashtech ADU2 array for measuring pitch, roll, and compass orientation, measured to an accuracy of about 0.4 degrees. One of the antennas also serves as the antenna for the Ashtech Z-Surveyor GPS receiver, which in combination with local base stations provides horizontal and vertical position to about 4 cm accuracy.
