TRANSCRIPT
What is GPS?
• GPS – Global Positioning System
• 32 available Satellites Orbiting
the earth
• Signal Availability 24 hrs/day -
7 days/week - 365 days/year
• Minimum of 28 Satellites available
• Covers all parts of the Globe
• 6 to 10 SVs in view most of the time
• Satellites are used as reference points to calculate your current position
• The GPS receiver uses the time it takes for a radio signal to reach the receiver from a satellite, that time is used to calculate the distance to the satellite
• Minimum of 4 satellites are needed to compute position (Latitude, Longitude, Altitude and Time)
We have 3 ways to improve accuracy
Use Software Filters Use DGPS (Differential Guidance Positioning Systems) Level 1 - EGNOS (EU) Level 2 - OmniStar VBS/XP/HP
Use RTK or (RTK) VRS Level 3 - RTK and RTK VRS use ground base stations
GPS accuracy is 5 to10 metres
Level 1 EGNOS – European Geostationary Navigation Overlay Service – Pass to Pass accuracy of ± 15 – 20cm – Absolute (Year to Year) 0.5m – 1m

Why do we use GPS?
Financial
•Reduce skips and overlaps
•More planted areas
•Minimise costs for seed, fertiliser, fuel, labour
Precise Field Layout
•Every plant gets a fair share of inputs
•Optimises planted areas
Control traffic patterns
•Reduce compaction – improve yields
Ergonomic
•Reduce operator stress and fatigue
•Operators can work longer hours, refreshed at end of day
•Levels of concentration are maintained all day
•Operator can concentrate on the machine
•Flexibility of labour
Example
• Drill Width of 4 metres
• Overlap of 15 – 16cm
• Equal to an overlap of 4%
• Over 1000 acres, its equal to working an area of 40 extra acres
