AFS

• Case IH precision farming system• Uses Global Positioning Systems (GPS) to

optimize operator efficiency • Provides field mapping • Yield & moisture monitoring– Sensors measure crop flow, moisture and

temperature and ground speed

AFS (cont)

• Prevents overlap• Provides year to year optimization• Can be transferred to different equipment• Partnered with Trimble• Precision planting• Precision fertilizer application• Assisted steering

GPS• Uses 24 satellites to locate position–

• Satellites put into orbit by US government for the military

• 1980s was made available for civilian use • No cost to use• Accurate to within 15 meters• Need a correction for more accuracy

Minimum 3 satellites for location – (longitude & latitude)

• 4 or more satellites for location and elevation

Corrections

• DGPS (Differential GPS) with beacon correction 8 inches pass to pass– The beacon receiver , at a known

location ,receives GPS signals. The beacon generates an equation. This equation is then sent to the GPS antennae on the vehicle- which then applies the correction.

Corrections

• DGPS with WAAS (Wide Area Augmentation System) & Omnistar correction services– 6 to 8 inches pass to pass– Correction signal sent to WAAS or Omnistar

satellite then back to GPS on vehicle which applies the correction

Corrections

• RTK (Real Time Kinematic) +/- 1 inch accuracy pass to pass and +/- 1 inch year to year repeatable – Base station set up within a 6 mile radius– Can be portable– Must be set on same spot every year

Pass to pass accuracy

• A Trimble GPS receiver with +/- 4 inch pass to pass accuracy means you get less than 4 inch skip or overlap 95% of the time

Year to year accuracy

• A +/- 1 inch accuracy means you can drive the same rows next year within 1 inch 95% of the time.

Benefits

• Aides or controls steering– Reduces operator fatigue– Integral steering control hydraulically– EZ-Steer system– Light bar– Straight rows

• Can control fertilizer application• Prevents skips and overlaps• Reduces compaction

One customer….

• On one 1500 acre application…– Decreased overlap saved $7500 in ammonia– Reduced fuel consumption by $600

Lab Exercises

• Locate components on equipment• Learn monitor operation• Set up a course• Operate equipment
