Laboratory and Test Facilities

  • GNSS software receiver / simulator with sensor fusion (in-house development)
  • RF laboratory for the generation of GNSS signals
  • GNSS constellation simulator (hardware simulator), commercial GNSS receiver
  • Parabolic antenna for satellite signal analysis
  • Inertial measurement units (RLG, FOG, MEMS) and commercial analysis software
  • Optical reference systems (3D scanner, multi-station system)
  • LiDAR measurement units
  • Programmable multicopters and rotating arms for reference motions
  • Wide variety of software tools (signal processing, positioning)

Our activities include theoretical studies, prototype hardware and software development, and application-oriented test campaigns. The range of navigation applications includes smartphones, autonomous driving and interplanetary flight, for example for asteroid mining.


Asteroid mining

A wide variety of measurement systems are available at the Institute and are used to check signals transmitted from satellites and to ensure compatibility with other radio services, for example.

UAVlite test system

A UAVlite test system is being established at the Institute in order to help us gain a precise understanding of the effects of signals in real environments. GNSS satellites are emulated by multicopters and transmit new navigation signals using a payload that has been developed at the Institute. A network of ground stations on the premises of the university receives these signals and determines UAVlite positions and clock errors. The UAVlite system is completed by a fixed GNSS testbed (terrestrial transmitter+receiver).

GNSS test track

A GNSS software transceiver has been in development at the Institute since 2005. As a receiver, it can receive and analyze all current GNSS signals as well as future signal options. Different positioning methods, such as single point, carrier-phase (RTK/PPP) and fusion positioning (inertial, LiDAR), are available. As a GNSS simulator, the transceiver can simulate the GNSS constellation. Further software developments include applications for the detection of wrong-way driving or for augmented reality as well as tools for using GNSS in civil aviation.
