Abstract

A GPS unit outputs a ground speed signal to an agricultural dispenser for applying chemicals to a field or for planting seeds. A GPS receiver receives satellite signals from a plurality of satellites, and outputs a vehicle ground speed signal based upon GPS calculations. A converter converts the vehicle ground speed signal to a series of pulses having a frequency indicative of the vehicle ground speed. The pulses are then transmitted to the agricultural dispenser which is pulled by a tractor to apply the desired amount of chemicals to the field or for planting the desired amount of seeds as a function of the vehicle ground speed.
