| National Galileo Test Bed GATE
GATE is
the abbreviation for "Galileo Test- und Entwicklungsumgebung" (Galieo Test-
and Development Environment). The project is funded by the German Aerospace
(Deutsches Zentrum für Luft- und Raumfahrt e.V.) and was launched in
2002. The project is conducted by a consortium of different enterprises and
institutions.
The main idea is to build up
a Galileo test environment by means of pseudolites. These pseudolites are
equipped with flexible signal generators which are able to emit GPS and
Galileo-like signals. Moreover, the signal generators are supposed to emit
signals with consideration of signal dynamics so that the signal seems to
originate from a real satellite (virtual satellite concept). GATE can be
used to test the new Galileo signals under realistic conditions or to analyze
interference and jamming characteristics (e.g. interference with DMEs and
radar facilities). The main purpose of this test bed is to provide a test
facility for different users (e.g. receiver manufacturers, service providers,...)
and allow tests of specific applications. Therefore, the corresponding
requirements of these users have to be considered during the development
of GATE.
