              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 real-
  time 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.
