Once upon a time…
Robot mowers could only work if there was a powered boundary line along a lawn’s perimeter. And they were limited to random cutting patterns, so they could only mow small lawns. As a result, larger areas could only be maintained by man-operated mowers… until now.
The future of unmanned mowing is now
The new Kress RTKn robot mowers extend unmanned mowing to larger areas. They efficiently operate in parallel lines and autonomously move from one area to another, as if they were driven by humans. No need for boundary wires, or on-site antennas.
Who will benefit from Kress RTKn?
Residential lawns. Large properties. Athletic fields. Public parks. Corporate facilities. Unmanned mowing is the ideal solution for countless applications, providing quiet and emission-free turf management that carries an operating cost of a fraction of manned mowing.
Nothing is better
Robotic mowers that make use of RTK require the installation of at least one station antenna for each lawn, which must be powered and placed in open sky. Kress RTKn delivers centimeter accuracy with no station antenna on site.
Economical
Avoid the extra cost that comes with antenna installation
Unplugged
No need to create additional electrical connections around the mowing area, since there are no antennas that need to be powered
Quick and simple
Once the mapping is done, the mower is ready to go
Unintrusive
No ugly antennas in the middle of the lawn or on the roof of the house
Dependable
Nothing can get damaged or stop operation due to electricity blackout
The Advantages of RTKn
Quick setup
Once the virtual boundary has been mapped and the charging station installed, you’re done -- no need to install on-site antennas.
Zero emission
No polluting exhaust fumes, no emission of greenhouse gas
Quiet operation
Hotels can manicure their lawns while guests are sleeping
Efficiency
The mower works in parallel lines, as an experienced landscaper would
Operational savings
Eliminates labor costs, has negligible impact on energy bills, and minimizes maintenance expenses when compared to the operational costs of ICE mowers
Stay in the know
With the Kress app on your smartphone, you can control and monitor your mower anytime, anywhere.
How it works?
Kress RTKn technology uses the global navigation satellite system (GNSS) to get autonomous geo-spatial positioning with 2 to 5 meters accuracy, then applies real-time kinematic (RTK) correction data to achieve centimeter-level accuracy.
RTKn: position accuracy to the power of network
To ensure centimeter-level accuracy, Kress’ expanding proprietary network of reference GNSS receivers continuously delivers RTK correction data to your mower via the mobile phone network.
What if there’s poor satellite signal?
A number of factors can degrade satellite positioning accuracy. Should satellite signals be blocked by buildings and trees, not even RTK correction data could help. Here’s where inertial navigation and odometry take over to precisely route the mower until it reaches an open sky area and satellite navigation is restored.
Micro manage your lawn with Multi Zone setup
Kress RTKn technology will finally let you have direct, precise control over distinct mowing zones. Just open your mobile app, mark the zones, and in case there’s a paved road or a road in between, trace a path for your Mission mower to reach them.

An inertial navigation system is typically formed of three orthogonal accelerometers and three orthogonal gyroscopes that measure tri-axial linear acceleration and angular velocity, respectively.
Inertial navigation, or dead reckoning, is based on motion-sensing devices connected to a computer that continuously calculates the position, velocity and orientation of a moving object. For moving objects that rely on external references, e.g. satellite navigation or computer-vision navigation, inertial navigation is used when such external references are temporarily unavailable. Inertial navigation is subject to cumulative errors. Accuracy depends on the precision of its motion-sensing devices and, most importantly, on the algorithm that computes data.
Did you know?
Although most of us associate dead reckoning with modern satellite navigation systems, the term appeared in the Oxford dictionary as early as 1613. At the time, dead reckoning was the primary method of determining longitude in marine navigation. Instead of motion-sensors, ingenious methods such as the ‘chip log’ were used to estimate the speed of a vessel through water.
