Spirent GSS7725
GNSS Interference Generator
Generate, Understand, and Protect Against
RF Interference
Whether you’re designing a global navigation satellite system
(GNSS) chipset, or integrating a receiver into a device, RF
interference can undermine positioning performance and
compromise user experience.
The Spirent GSS7725 is designed to let you quickly
playback RF interference signals, under fully repeatable, lab
conditions. Combined with a GNSS simulator, it will help you:
• Understand exactly how your product will respond to
RF interference
• Test RF interference’s impact on product performance
• Prepare for a positive user experience and product success
RF Interference—a Growing Threat
RF interference—whether naturally occurring in the
atmosphere, man-made but accidental, or created
deliberately with low-cost RF jamming devices—is a serious
and mounting threat to GNSS performance.
And as more products and industries grow to depend on
accurate, robust GNSS positioning and timing, its potential
to cause damage grows: from driving dissatised users
to return their mobile devices, to compromising critical
infrastructure, and risking network failures.
Introducing GSS7725
The Spirent GSS7725 is a dedicated RF interference
generator that turns I/Q les into interference signals.
Combined with a GNSS simulator, the GSS7725 lets you test
your chipset or device in a variety of different interference
environments, under controlled, repeatable conditions.
Unlike other standalone interference generators, the
GSS7725 seamlessly integrates with Spirent GNSS simulators,
test packs and automation tool. And with a competitive price
point, it’s ideal for commercial enterprises looking for a
simpler way to test for GNSS interference—without going over
budget.

Test a Range of Interference Models
The GSS7725 uses I/Q les to quickly playback RF
interference waveforms. These can be loaded into the
GSS7725 from various sources:
• The Spirent Vulnerabilities and Threats Test Pack—this
contains 33 pre-recorded interference signals, covering a
broad spectrum of real-world interference types
• The Spirent GSS200D—you can access interference you
have recorded and stored in PT Cloud
• Spirent Professional Services—we can work with you to
develop the custom I/Q les you need
Want to test even faster? The GSS7725 works alongside
Spirent PT TestBench to support automated testing of RF
interference scenarios.
Key Features
• Convert I/Q les into interference signals
• Seamlessly integrate with Spirent GNSS simulators
and Test Packs
• Embedded GNSS and interference signal combiner
• Alter interference signal levels in real-time
• A single, dedicated unit for testing real interference.
Specications
• Centre Frequency Range 0.85 to 2.2 GHz
