What is GPS • Global Positioning System (GPS) is a satellite-based navigation system formed from a constellation of 24 satellites and their ground station. • Electronically identifying and recording the location of an object or person. • There are five monitor stations: Hawaii, Ascension Island, Diego Garcia, Kwajalein, and Colorado Springs
GPS monitor stations
Future of precision agriculture • Automation or robot, which is supported by various sensors can become a reality in precision agriculture. • GPS technology can be used with different sensors to provide for more complex applications. • Driverless tractor that can adapt to different agriculture applications by adding with different equipments.
Driverless Tractor
• Parallel swathing – reduce overlap between spray vehicle passes. • Precision path tracking – planting based on realtime kinematic (RTK) GPS, eliminating row markers can reduce planting equipment cost. • Remote guidance – remove the operator from dangerous tasks. • Operator aids for the handicapped – allows disable farmers to perform field operations. • Multi-vehicle cooperation – enhance productivity for operations typically coordinated between operators in different vehicles.
Conclusion • GPS and Driverless tractors can be the future of precision agriculture. • Implementing autonomous technologies will be priorities for research. • The research outcome can be very beneficial to human. • Automated benefits are associated with increased field efficiency capacity through faster travel speeds and accuracy and also extending the work day into night time or during low-light operation. • Provide a safe working environment is very important factor for robot design.
