GNSS-based speed sensors (GNSS receivers), inertial navigation systems (INS) or special speed measurement devices - are indispensable in safety-critical and industrial applications. These sensors are used in tvarious industries, including automotive, aerospace, energy and environmental technology. To ensure they consistently deliver accurate and reliable measurements, regular calibration is essential for safety, quality and compliance with legal standards.
We are your partner for dynamic, DAkkS-accredited calibration
Unlike many other providers, who only perform static calibration of your inertial navigation systems (INS), we offer comprehensive dynamic calibration that complies with the requirements of traffic bulletin no. 156 (valid since 2024). In addition to calibrating amplitude linearity, our procedures include measuring the amplitude frequency response of the device under test in the range from 0.5 Hz to 16 Hz, thus ensuring maximum accuracy. With DAkkS-accredited processes, short turnaround times and competitive prices, we are one of the few specialized service providers in Germany for the professional calibration of speed sensors.
We offer:
- Accredited, dynamic calibration
- Highest level of service
- Lowest possible measurement uncertainty
- Traceable and reproducible measurements
- Short processing time
- Competitive price

Speed sensors are used, among other things in the automotive industry (vehicle and wheel speed, ABS, ADAS), industrial automation (conveyor belts, quality control), aerospace (airspeed, test benches), maritime applications (ship speed), mechanical engineering (speed and vibration measurement), R&D (measuring vehicles, flow research) and energy and environmental technology (wind power, flow measurement).
Accurate measurements are essential for many applications. Precise speed sensors ensure safety, enhance product quality, optimize processes and help to meet legal standards such as ISO/IEC 17025. In the scientific field, they ensure reliable and traceable measurement results.
Regular calibration of speed sensors is important in order to avoid measurement errors caused by ageing, wear and tear, or environmental influences. Our calibration services ensure compliance with standards such as ISO 9001 and ISO/IEC 17025, provide documented quality certificates, help extend the service life of the sensors and reduce failure and maintenance costs.
GNSS, or Global Navigation Satellite System, is a group of satellite systems used for precise positioning and navigation. The best-known GNSS is the U.S.-operated Global Positioning System (GPS), but there are other systems such as the European Galileo, the Russian GLONASS, and the Chinese Beidou. This technology is widely used in navigation systems for vehicles, aircraft, ships and mobile devices, as well as in areas such as surveying, agriculture and emergency services, where precise positioning is critical.
A GPS-based speedometer uses GPS signals to calculate speed based on changes in position. It typically uses the US GPS system exclusively and provides analog or digital speed signals for vehicles. It is often less expensive, requiring only a simple antenna and lower update rate. However, in the event of signal loss, for example in tunnels or buildings, the measurement may fail.
