The global positioning system is comprised of 24 satellites (plus a few spares) orbiting the earth. The satellites have an orbital period of about 12 hours. This means that each satellite will circle the earth about twice in a 24-hour period. The satellite orbits are about 12,500 miles above the earth’s surface. GPS has found enormous applications in agriculture. GPS and associated navigation systems are used in many types of agricultural opera¬tions. This technology is used by farmers to manage their crop land. Today, GPS based systems are found on a variety of agricultural machinery, assisting farmers with day-to-day activities. These systems are useful particularly in applying pesticides, lime, and fertilizers and in tracking wide planters/drills or large grain-harvesting platforms. This technology reduces the chance of misapplication of agrochemicals and has the potential to safeguard water quality. This technology is useful in recording spatial yield data in the field. Use of GPS navigation in agrochemical application with ground equipment has grown rapidly, and commercial applicators are quickly adopting the tool. The combination of Global Positioning System (GPS) and mobile mapping provide the agriculturist with a new capability of gathering information for implementing decision-based precision agriculture. Improving the agricultural process can maximizes financial return and increases the stewardship of land, water, and related natural resources.
