The German Galileo Test and Development Environment
The development of products, services and applications is a key factor for the commercial success of a satellite navigation system. GATE is a unique outdoor test- and development environment for the emerging Galileo & GPS satellite navigation market. Consisting of eight virtual „Galileo satellites" located on top of several mountains around the GATE test area in Berchtesgaden (Germany), a well suited topology is available to support different testing scenarios. GATE closes the gap between laboratory based constellation simulations and the real-world Galileo system, with its 18 satellites IOC constellation planned to be available in 2014.
Test your products and applications today with GATE to be ready for Galileo tomorrow!
The installation and experimental operation phase of GATE has been completed successfully. Since August 2008 it is already possible for companies and research institutes to perform their Galileo experiments with GATE. After its extension to eight transmitting stations the test range was officially opened in Febuary 2011. It is planned to operate GATE at least until the full operational capability of Galileo. IFEN GmbH is the operator of the test range till the end of 2013.
GATE Test Range
The GATE test bed cornerstones are eight ground transmitters, emitting the Galileo signals into the test area in the region of Berchtesgaden (Germany). Two monitoring stations located within the test area are receiving and processing these signals. A central processing facility which is the core of GATE is steering and controlling the signals transmitted. These alileo signals are fully compliant to the Galileo OS ICD specification. With the GATE "Virtual Satellite Mode" a realistic moving Galileo satellite constellation can be simulated, supporting commercial Galileo receivers without any modification. Furthermore, the integration of additional sensors like odometer or inertial sensors allows testing of sophisticated integrated navigation systems and applications under realistic environmental and dynamic conditions, e.g. including multipath and interference effects. The four Galileo IOV satellites available from 2011 onwards can be used in combination with the eight GATE "satellites", enabling up to twelve visible Galileo satellites, thus reflecting a complete Galileo FOC constellation. With full control over the eight GATE "Galileo satellites", feared events can be simulated enabling evaluation of new user integrity (RAIM) algorithmic concepts and implementations. (text: IFEN GmbH)
