Abstract

A rover for precisely determining the topography of a given parcel by contacting the surface of the parcel includes a GPS module and at least one sensor wheel. The GPS module may be mounted adjacent to and work in concert with the sensor wheel. The attitude and heading of the sensor wheel may be measured with another sensor, such as an AHRS, and the angle of the sensor wheel may be measured with a rotation position sensor. The various data points may be distilled to accurately measure the topography of a given parcel when the relative positions of the GPS module and the center of the sensor wheel are constant.
