  3. Ten Agricultural and Biological Engineering Achievements that Changed the World

  4. 10 Engineering Achievements • Development of the Agricultural Tractor • Rural Electrification • Self-Propelled Combine • Center Pivot for Irrigation • International Harvester Cotton Picker • Milking Machine • Conservation Tillage • ASABE Standardization Procedure • Rubber Tires on Tractors • Refrigerated On-Farm Milk Storage

  5. The Influence of Precision Agriculture!

  6. Precision Agriculture • Precise information on agronomic factors. • Precise selection and placement of crop inputs. • Precise position and travel information.

  7. GPS Systems

  8. GPS Global Positioning System • Characteristics • Free • Accurate • Reliable • Worldwide • Unlimited user capacity 60’s TRANSIT – doppler system ’95 Fully Operational Condition (FOC)

  9. MILITARY MARITIME AUTOMOTIVE SURVEYING AVIATION AGRICULTURE FORESTRY ENVIRONMENTAL PUBLIC SAFETY HIKING HUNTING NATURE STUDY FISHING BOATING BIKING SKIING SNOWMOBILING GEOCACHING GOLF ! SOME GPS APPLICATIONS COMMERCE & GOVERNMENT RECREATIONAL

  10. Space Segment • 28 Rockwell satellites • 7.5 yr life span • 6 orbital planes @ 55 degree orbits • 2 orbits everyday • Very high orbit (20,200 km) • Radius of Earth ~ 8000 mi (~12,900 )

  11. How GPS works… Satellite signals are broadcast at the speed of light (186,000 miles per second) • Distance to satellite =11,200 miles 300,000 km/s a 1/1,000,000 sec Error =>300 m pos. Error

  25. GPS Options for Ag RTK Fixed 1cm GPS 7 - 10m RTK Float 20cm DGPS .5 - 5m Autonomous 50 - 100m S/A

  26. DGPS Accuracy – Trimble Units

  27. Sprayer Navigation

  28. GPS Navigation Aids:

  29. GPS Navigation vs Foam Markers Reliable and more accurateAccuracy at higher speedsEasily used with spinner spreadersEasy to use – less skilled operatorEffective over growing cropsAllows operation when visibility is poorLess affected by weatherLower recurring costsReduces operator fatigue and eye strainLower set-up timeNot effected by wind or boom bounceReduces overlaps and skipsReduces need for people in sprayed areas
