Spirent, the world leader in navigation and positioning test solutions, has developed the GSS7765 Interference Simulation System as a ready-to-use integrated interference signal generator.
The GSS7765 package, when combined with one of Spirent’s GNSS satellite constellation simulators, offers a comprehensive solution for testing satellite navigation equipment in the presence of intentional or unintentional RF interference.
GSS7765 is designed for use with Spirent’s GNSS constellation simulators and the package is supported by Spirent’s SimGEN for Windows® software suite, enabling complex test cases to be readily achieved.
The GSS7765 offers a broad range of interfering signal options which may be used to represent a varied array of threat sources. GSS7765 allows the tester to generate multiple simultaneous interference sources including AM, FM, CW, band limited white noise, pulsed or other waveforms. The GSS7765 can be configured to support up to 4 fully independent interference sources. It includes modelled power levels, consistent with vehicle motion.
If you are looking to test interference on satellite navigation equipment then the GSS7765 package offers a flexible and scalable interference source generator.
Spirent’s GSS7765 offers a number of benefits making it a ready-to-use, flexible and scalable interference source generator. Benefits include:
Flexible
- The GSS7765 package comprises one or more high quality commercial signal generators plus an Interference Combination Unit (ICU)
- GSS7765 is supported by Spirent’s SimGEN for Windows® software suite supporting three operating modes. Fixed mode allows a scripted series of events to be defined. Modelled mode allows the user to position interference sources in the scenario and model the level effects as the simulated vehicle moves within the specified environment. Interactive mode enables the interference source power level and modulation characteristics to be controlled in real-time
- The GSS7765 offers a very broad range of interfering signal options, which may be used to represent a varied array of threat sources
- Interference signals available include continuous wave (CW), AM, FM, some of which may be pulsed
- The generator also supports noise generation with variable bandwidth
Scalable
- The GSS7765 can be configured to support up to 4 fully independent interference sources by the addition of extra generators to the single-source base configuration
Spirent’s GSS7765 has a range of user focused and adaptable features:
- Control via Spirent’s SimGen for Windows® software
- Fully supported in SimGen for Windows® scenarios
- Full control over interference signal content and dynamics
- Wide range of interference types
- Large power and frequency range
- Modelled and static operating modes
- Interactive mode enables power and modulation to be controlled in real-time
- Multiple configurations
- Up to 4 fully independent interference sources supported
- Compatible with embedded jamming (where available on the underlying system)
The GSS7765 is one of many options available to enhance the capability of your Spirent simulator. Other options available include:
- Coherent inertial sensor simulation system (SimINERTIAL)
- Data capture and handling package via RS422 or MIL-1553B (authorised customers only)
