Ultimate precision with AFS RTK+

RTK+ (Real Time Kinematic) is the top-end technology that ensures a fast, dependable signal and maximum accuracy in all conditions, regardless of field location. For the ultimate precision, an additional wireless correction signal from a mobile communications network — with the modem fixed to the tractor and a range of up to 30 km — provides the technology you need.

  • Cost savings — keeping work as parallel as possible means lower fuel costs, reduced inputs of seeds, fertilisers and plant protection products, and less time to get the job done.
  • Efficiency — accuracy and fast connections everywhere and at any time reduce application overlaps and skips, allowing more accurate placement of inputs including fertiliser and herbicides.
  • Simplicity — a single contact for your hardware and correction signal, plus a single subscription for unlimited access, compatible with all hardware.
  • Repeatability — repeatability even in the narrowest rows for better control of field traffic, keeping tyre tracks on the same path and reducing compaction.
  • No signal interruption — maintain centimetre-level accuracy indefinitely; signal losses can be bridged for up to 20 minutes from start-up, so you just keep going.
