High precision and integrity are only achieved with today's "Global Navigation Satellite Systems" (GNSS) in positioning through the use of additional services and systems. In addition, it is increasingly necessary to bridge coverage gaps by incorporating additional sensors.

• We are opening up new fields of application for the automated control of vehicles and machines in safety-critical environments.
• With the development of robust receivers, we are achieving an unprecedented level of reliability and interference resistance. We are thus supporting the growing autonomy in traffic and enabling new applications, for example in the areas of civil engineering, agriculture, and forestry.
• We are also safeguarding the availability of navigation services by developing terrestrial alternative systems. By providing additional services, we are expanding the potential uses of existing systems.

Laboratories and large-scale Facilities - Mission Global Positioning

Antenna measurement chamber Starlab StarLab is a near-field multi-probe system with spherical geometry and an important tool for accompanying antenna developments at the Institute. Full article

Antenna Measuring System AMA The free-field antenna measuring system AMA can be used to determine the radiation or reception characteristics of antennas in the far field. Full article

Clock Laboratories In the three different laboratories, research is carried out on time synchronisation, the generation of a system time from several clocks (ensemble time), the verification of system time algorithms (composite clock) with real measurement data or time transfer, among other things. Full article

TASC - Threat Analysis and Simulation Center GNSS data are collected and analysed with the sensor technology of the facilities. The aim is to describe unusual effects whose influence can lead to interference with satellite navigation systems, especially Galileo, to incorrect position solutions and thus also to endanger users. Full article

GNSS verification and analysis facility With this verification facility for satellite signals, the signals from navigation satellites (e.g. Galileo, GPS, GLONASS, COMPASS) can be received and analysed with the highest accuracy. Full article

EVNet - Experimentation and Verification Network This system of 13 sensor stations can acquire, process and distribute GNSS and GNSS-related measurement data in near-real time. Full article

MASTER - Multi-output Advanced Signal Test Environment for Receivers MASTER is a unique and powerful hardware simulator for testing and evaluating the quality of GNSS receivers, allowing the simulation of a complete GNSS constellation. Full article
