Challenge

Machines need accurate information about their actual speed under real-world operating conditions.

In practice, speed calculated from the rotation of wheels or transmission components does not always reflect the machine’s actual movement relative to the ground surface.

When operating on soil, gravel, sand, snow, wet ground, or in quarry conditions, wheel slip, sliding, and changes in surface traction can occur. As a result, onboard systems may receive incorrect speed data.

For agricultural machinery, this affects the accuracy of seeding, fertilizing, and applying crop protection products. For quarry, mining, and industrial machinery, it affects motion control, safety, productivity, and the operation of automated systems.

Machines need a sensor that measures not calculated speed, but the actual ground speed — regardless of wheel condition, load, surface type, and operating conditions.

Solution

True Ground Speed Radar Sensor for Mobile Machinery

We develop a true speed radar sensor for installation on various types of ground vehicles and mobile machinery.

The sensor measures the machine’s speed relative to the ground surface without contact and transmits the data to the onboard control system, controller, terminal, telematics module, or automation system.

The solution can be used as a standalone source of speed data or as an additional channel for comparison with wheel speed sensors, transmission-based sensors, inertial systems, and satellite navigation systems.

The sensor helps improve the accuracy of technological operations, monitor wheel slip, enhance the quality of automatic control, and provide stable motion data under challenging operating conditions.

The solution can be adapted to a specific platform: tractor, sprayer, seeder, combine harvester, mining dump truck, loader, road construction machine, municipal vehicle, test vehicle, or special-purpose transport platform.

FAQ

Frequently Asked Questions

What is the difference between a true speed sensor and a wheel speed sensor?

A wheel speed sensor calculates speed based on the rotation of the wheel or transmission. In cases of wheel slip, this data may differ from the actual travel speed. A radar sensor measures movement relative to the ground surface, so it provides the true speed of the vehicle or machine.

What applications can the sensor be used in?

The sensor is suitable for tractors, sprayers, seeders, combines, mining dump trucks, loaders, road construction machinery, municipal vehicles, test vehicles, and special-purpose transport platforms.

What is it used for in agriculture?

It helps perform operations more accurately when speed affects process quality, such as seeding, spraying, fertilizing, soil cultivation, and harvesting. In cases of wheel slip, the sensor helps maintain accurate data for dosing and control.

What is it used for on mining and quarry equipment?

In quarries and industrial sites, machines often operate on difficult surfaces. A radar sensor helps obtain reliable speed data, control movement, and use this data in safety, monitoring, and automation systems.

Can the sensor be customized for a specific machine?

Yes. The mounting, interfaces, output data format, processing algorithms, and installation parameters can be adapted to the requirements of a specific machine or control system.

Can the sensor be used together with GPS/GLONASS?

Yes. The sensor can work together with satellite navigation, inertial systems, and wheel speed sensors. In this case, it improves the reliability of motion data and can be used as an independent source of true speed.
