Abstract:	EADS Astrium has developed a GNSS signal generator for Galileo, GPS, EGNOS and WAAS signals. It is a flexible and modular signal generation unit for laboratory & field testing of GNSS equipment as well as for providing GNSS Pseudolite signals in various environments. Typical applications of the NSG 5100 include GNSS chipset and equipment development, GNSS receiver development as well as mass production testing, all Galileo and GPS signal analysis tasks and provision of additional ground based ranging signals. The NSG 5100 is fully controllable concerning the PRN codes, signal power level, Doppler shift, message contents, message data rates etc. For users interested in Galileo/GPS Local Elements and provision of additional ranging signals the NSG 5100 supports high power transmitting and pulsing of the signal. The NSG 5100 comes with a PC host software which allows easy command and control of the unit via a standard LAN interface. With the software internal scenario editor the user is able to create own simulation scenarios and let the NSG 5100 perform complex simulation runs on one click. Since the navigation message of Galileo contains several extended data services the software comes with a navigation message editor to create specific navigation data streams. The unit has been upgraded in 2008 to support GPS L5 and Galileo PRS signals. Extensive laboratory as well as field trial tests using the NSG5100 broadcasting outdoor signals (e.g. using the SEA GATE Galileo testbed) have been performed in order to evaluate the compatibility and performance of the GNSS signals and the receivers. The presentation will show results from laboratory tests with various Galileo receivers (e.g. Novatel Europak GPS+Galileo, Septentrio AsteRx etc.) and performance results
