Technical Equipment

3D-Positioning System

3D-Positioning System

A unique 3D positioning system

The Test and Application Center L.I.N.K has a globally unique 3D location system for the ultra-precise evaluation of positioning systems. Positioning systems can be evaluated automatically and standardized regarding the performance data across a total area of 850 square metres. In addition, the repeat accuracy of 1-2 mm enables follow-up tests to be carried out in identical scenarios. It is also possible to evaluate complex test series either in a standard process or to configure client-specific realistic application scenarios in dynamic test runs. Areas of application are to be found, for example, in manufacturing and security technology, the automotive sector, ambient assisted living (AAL), logistics, asset management and leisure applications.

Optical reference system (iGPS)

The Test and Application Center L.I.N.K is also equipped with the iGPS laser reference system. This exceptionally precise system can define the three-dimensional position of objects within an accuracy of 0.2 mm in both dynamic and static measuring scenarios. The mobile version of the reference system also enables measurements to be taken in the open air as well as unbroken test runs between indoor and outdoor areas.

RFID positioning unit

The purpose of the RFID positioning unit lies in the investigation and demonstration of the group reading process of UHF-RFID systems. RFID gateways are automatically traversed under controlled conditions on multiple occasions and then analyzed statistically. This enables system parameters, for example antenna positioning and various readers, to be tested. A 3D real time visualization of the transponder reading processes provides insight into the RFID reader behavior and supports the optimization of TAG positioning on complex metallic objects. The positioning unit can also be used to undertake valuable preliminary assessments which act as an ideal supplement to genuine field tests.

A variety of measuring systems have been installed in the Test and Application Center which can be combined depending on the application:
