localization and indoor navigation

The research focus of the competence center is object-tracking and navigation systems. The director of CCASS, Prof. Dr. Markus Haid, is one of the leaders in the field of low-cost inertial navigation.

Inertial navigation which is based on orthogonal low-cost accelerometers and attitude sensors, possibly determines the position and attitude of a moving object in space without using any signal from its environment. These portable systems are very flexible systems mounted with accelerometers and gyroscopes.

These MEMS sensors are generally known from the display rotation functionality in smartphones and from the Wii controller of the Nintendo playing console. Originally they were developed for Airbag and ESP systems. The challenge to realize indoor navigation systems based on this sensor technology is obvious from the fact that there is no indoor navigation app in any smartphone. It is necessary to realize these systems intelligent and application specific algorithms. This is the core know-how of the CCASS.

In the age of Internet of Things and Industrial 4.0 the tracking of tools, persons and producer goods in smart homes, smart factories and assistant living environments, is of major interest to companies and associations. 


In additional to the inertial tracking, the CCASS also offers solutions for reference based tracking systems for other applications. For cell-based tracking and localization approaches the CASS develop Bluetooth based solutions.

ultra wide band (UWB)

The CCASS scientists can realize a reference based navigation with an accuracy of a few centimeters via an uwb approach.

ins + x

The CCASS combines reference less and reference based navigation and localization solutions for every possible application, with the INS + X approach.
