To expand its GNSS support, IZT has cooperated with TeleOrbit, the marketing & sales unit of TeleConsult Austria. To enable the generation of GNSS signals provided by the GIPSIE software from TeleOrbit to be integrated into the feature set of the IZT S1000 signal generator. The signal generator with its broad frequency range and the Virtual Signal Generator (VSG) channels enables the similar generation of various GNSS standards in one device which can be combined with interferers or broadcast signals.

In addition, it supports the combination with recorded signals. The software-based GNSS multi-system performance simulation environment GIPSIE from TeleOrbit consists of two modules, the satellite constellation simulator (SCS) and the intermediate frequency simulator (IFS).

While the SCS simulates the satellite orbits, the IFS generates complex baseband signals for the virtual signal generators of the IZT S1000.The signal generator currently supports multi-system, multi-frequency scenarios of GPS L1/L2/L5 and Galileo E1/E5/E6.

The integration with the GIPSIE software enables the IZT S1000 signal generator to generate ideal GNSS signals for different standards. Based on the new software option the signal generator simulates the signal propagation from the satellite to the receiver.

Furthermore interferers can be added using the VSGs of the signal generator to examine their influence on the signal propagation. At the end the related analogue signal will be released to the DUT (device under test) of the client.

The combination of the signal generator and the GNSS software enables significant cost savings during receiver development, verification, qualification and certification, while time consuming test runs and validations are unnecessary.

The broad spectrum of applications ranges from end-of-line testing in production to the development; optimizing, test and verification of acquisition, tracking and positioning algorithms; the generation of multipath strategies and algorithms to minimise interference susceptibility; the evaluation of baseband receiver hardware or positioning algorithms and the identification of ideal settings/adjustments to improve the capability of GNSS receivers, etc.
