Multi-sensor fusion and status monitoring

No single technology can meet all operating requirements.
Multi-sensor fusion offers a solution by combining multiple
technologies and sources of information, with the goal of
increasing the precision, robustness and avai-lability
of geolocation signals. Inertial sensor systems are the
ideal support for such applications, especially given that this
technology also enables the static and dynamic monitoring of
moving objects.

Global Navigation Satellite System - GNSS

Satellite-based navigation can be used independently of
other infrastructures in outdoor environments. We develop
tailor-made, high-precision receivers for specifi c applications
that process signals from a combination of different sources
including GPS, Galileo, EGNOS, and WLAN. As well as being
free from infrastructure constraints, our GNSS solutions
are uniquely precise, reliable and secure.

Time-of-flight measurement

Positioning strategies based on time-of-fl ight (TOF) measurement
allow objects to be located with a high degree of
precision. If ultrawideband radio communication is used, the
radiated signals can even penetrate walls. In essence, this
method involves measuring the time it takes for a signal to
travel from the transmitter to the receiver. Time-differenceof-
arrival (TDOA) systems use such data to determine the
location of objects at different infrastructure points precisely
and reliably.

Received signal strength indicators

Received signal strength indicators (RSSI) are typically used
in communication networks to enable mobile devices to
determine their geographical location in an urban or indoor
environment by reference to base stations utilizing Bluetooth,
WLAN, GSM or UMTS protocols. The advantages of such
solutions are their low cost and the high number of
available transmitters.

Inductive position sensing

This method works by monitoring changes in the magnetic
fi eld generated by moving objects as they pass over inductive
sensors. It is commonly used in geofencing applications.
This type of system offers the best performance in terms of
reliability, precision, and the number of transmitters.

Optical position sensing

This method typically involves the use of infrared cameras.
The line-of-sight optical path required by the photodetectors
results in highly precise measurements and low cost
factors. If optical position sensing is combined with a radio
detection system, reliability can be improved both within and
beyond the line of sight.
