Understand positioning systems’ interference performance

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.

Features & Benefits

Market-leading accuracy and fidelity
High quality simulation - built on 30 years’ experience - improves system accuracy and reduces field testing, debug times.
Flexible configuration
The system comprises one or more high quality commercial signal generators plus an Interference Combination Unit (ICU), and offers a very broad range of interfering signal options.
Powerful software
GSS7765 is supported by Spirent’s SimGEN™ for Windows® software suite supporting three operating modes.
Scalable
The GSS7765 supports up to four fully independent interference sources by the addition of extra generators to the single-source base configuration.

Understand interference effects

PNT systems can be affected by a wide range of interference which can result in loss of position or timing accuracy, or even worse, cease operating altogether. Solar flares, radio emissions in nearby bands, deliberate jamming or spoofing can all contribute, meaning that designers need to understand and test the resilience of products and services that rely on high accuracy navigation and the precision timing that GNSS can provide.
