Abstract
A land-leveling system that uses the Global Positioning System is provided. The system provides for an earth-moving machine mounted with an antenna that receives GPS signals from the satellites of the Global Positioning System. The earth-moving machine comprises a vehicle attached to a work implement, which is also connected to an actuator. A decision unit mounted on the vehicle sends control signals to the actuator, which controls the elevation of the work implement. These control signals are generated using the signals received from the antenna and the desired grade map. This system has an increased coverage area, more accuracy and round-the-clock operability. The system could be used to carry out all the land-leveling operations viz. surveying, leveling and verifying.
