seed-senseReal Time Kinematic (RTK) satellite navigation is a technique used in land survey and in automatic guidance (agriculture) based on the use of carrier phase measurements of the GPS signals where a single reference station provides the real-time corrections to a rover vehicle (tractor, combine etc.) to a level of accuracy down to a centimetre.

How RTK System works.

The RTK system consists of a local base station near the field or farm that transmits corrections to the StarFire 3000 receiver on the RTK System equipped vehicle. The base station monitors the constellation of GPS satellites and continuously calculates a position.

As the base station is not moving, errors can be calculated in real-time. These fluctuations are then sent to the vehicle via the RTK System radio. The vehicle’s receiver uses this information to calculate a highly accurate, corrected position.

Precision pays.

Because AutoTrac RTK System optimises your guidance performance it also optimises your return on investment.
