Spirent communications is a global designer of state-of-the-art test solutions, for communications and satellite navigation sectors (Spirent - Positioning & Navigation). Spirent’s unrivalled experience and expertise in GNSS simulation ensures accurate results that customers trust and rely on to evaluate their products and applications. Spirent designs and produces signal simulators for Global Navigation Satellite Systems (GNSS) such as Global Positioning System (GPS), Russian GLONASS, European GALILEO, Chinese COMPASS regional augmentation systems (such as WAAS, EGNOS and MSAS) and regional positioning systems (such as QZSS and IRNSS)
Spirent GNSS simulator is a computer-controlled RF signal generator with extremely high accuracy & fidelity with flexible scenario generation tools for different vehicle types. It supports a range of modelling options for codes, signals and variables, receiver antennas, satellite constellation and other errors in a controlled environment. The setup provides excellent repeatability and control with a range of truth data for evaluation and testing. Spirent is based in the UK.
GNSS simulators from Spirent provide a superior alternative for testing compared to using actual GNSS signals in a live environment (live sky).
Some of the benefits of using a GNSS simulators are:
Simulators are available to suite customer requirements, ranging from dual frequency, multiple constellations system of GSS9000 to single frequency multiple constellation standalone system of GSS6700 to a single channel single frequency system of GSS6300/GSS6300M.
The Spirent GSS9000 Multi-Frequency, Multi-GNSS RF Constellation Simulator sets a new standard of excellence in GNSS RF Simulation for R&D and Performance Test.
The GSS9000 provides numerous benefits to the all those working in high-end GNSS technology and application development, including comprehensive and feature-rich simulation and full control of all aspects of the GNSS operating environment, inherent repeatability and the ability to apply systematic errors and incidents that are impossible to realise using actual satellite signals.
For comprehensive GSS9000 information:
The GSS6700 supports any combination of GPS/SBAS, GLONASS and Galileo L1 signals and provides accurate, repeatable combined multi-GNSS signals. The GSS6700 can be configured with up to 12 channels of one constellation only or with multiple constellations. Some features of GSS6700 are:
For comprehensive GSS6700 information:
The GSS6300M is the ideal entry-level multi-channel GNSS simulator for busy receiver integrators, application developers, aftercare and production testing environments. Its 4 or 8 channels of operation can simulate L1/E1 signals from GPS/SBAS/QZSS, GLONASS, BeiDou and Galileo to test the fundamental positioning capabilities of any GNSS device.
