Once upon a time…
In the past, robot mowers required laying a powered wire along the perimeter of the working area. Mowers used to follow a random pattern, so they could only deal with relatively small lawns. Larger areas still had to be maintained by man-operated lawn tractors or zero turn.
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 an area to another, as if they were driven by humans. No need for boundary wires, nor on-site antennas.
Who will benefit from Kress RTKn
Large properties. Facilities. Sports fields. Golf courses. Public parks. You count them. Unmanned mowing is the ideal solution for countless applications, providing quiet, emission-free turf management, with an operating cost that is 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.
Convenient
No extra cost for the station antenna and its installation
Unplugged
No need to bring electricity in the lawn or over the roof for powering the station antenna
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 your Kress dealer has mapped the areas and installed the charging station, you’re done. No on-site antennas installation needed.
Zero emission
No polluting exhaust fumes, no emission of greenhouse gas
Quiet operation
Hotels can get their lawns manicured when customers are asleep.
Efficiency
The mower works in parallel lines, mowing large lawns as quickly as an experienced landscaper.
Operational savings
No labor cost, negligible impact on your energy bill, minimal maintenance expense as compared to 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.
