It has been 25 years since John Deere introduced the first StarFire receiver and GreenStar display – kick-starting its automated guidance range.
The GreenStar was reportedly the first system to show whether an operator should steer left or right, improving pass-to-pass accuracy. This was quickly followed by AutoTrac the next year, which automated the steering based on the GPS signal.
While the initial AutoTrac system offered 30cm accuracy, by 2004, RTK was introduced, enabling accuracy down to 2.5cm. This made it possible to follow the same tracks over multiple seasons, with both the tractors and the combines.

If RTK was the most advanced system available in 2004, by 2020, John Deere had developed systems that better utilised the guidance data. AutoPath Rows recorded the actual tracks of row unit to enable precise repetition, while AutoPath Boundaries (launched in 2024) enables the optimised path across the field to be calculated.
How we collect the data has changed as well. Initial systems, such as FieldDoc used a keycard that had to be manually read in the office. Now JDLink automatically transfers data wirelessly to the John Deere Operations Center.
DataSync enables every machine within the Operations Center to share guidance lines and boundaries. The Work Planner (2022) enables setup information for tasks to be created within the Operations Center, with the in-cab display automatically loading up the relevant information when the tractor crosses the field boundary.
From the original GreenStar display (2001), display generations progressed through Generation 2 (2005), Generation 3 (2011), Generation 4 (2014) and Generation 5 (2023). Receiver development has followed a similar path, from the original StarFire (2001) to StarFire iTC (2004), StarFire 300 (2008), StarFire 3000 (2010), StarFire 6000 (2016) and the latest StarFire 7500 (2024).
“Over the past 25 years, precision agriculture has moved from early visual guidance and manual data handling to integrated, automated workflows,” said Peter Koch, production system marketing manager for Precision Technologies. “From keycards to cloud connectivity, and from steering support to highly accurate guidance and automated path creation, the aim has remained the same: to make fieldwork simpler, more precise and more efficient.”
