Combining high dynamic range and a wide bandwidth with high recording
fidelity, facilitated by the premium OCXO, the GSS6450 delivers the realism andrich real-world detail needed for comprehensive testing.

Unrivalled Capability
In addition to supporting all current GNSS signals, the GSS6450 facilitates thedevelopment of integrated PNT technologies through the ability to record any

most capable record & playback system available for developers in industries
ranging from automotive to handset to defence.

Ultimate Flexibility
Feature key configuration, field upgrades, and simple re-configuration between
runs make the GSS6450 ideal for efficient data collection exercises, as well as forGSS6450

Performance
Up to 80 MHz bandwidth enables users to capture a significant
portion of the RF spectrum in a single channel, opening up
the ability to record signals such as WiFi as well as GNSS. Inaddition, users can be confident that all signal sidelobes andApplications
Automotive
The GSS6450 is the ideal partner for automotive

High frequency stability on record and playback through
OCXO ensures you always get a representative playback of therecording. Particularly for precise positioning applications, thiscertainty that error sources were captured in the field, rather
than added by the instrument, is critical.
Multi-frequency GNSS and additional signals capability is
helping in the shift towards multi-frequency, improving test
coverage in just a single unit.

Chipset
Already established as a key instrument in thedevelopment of new chipsets, the GSS6450 offers:• Capability to have record-only and playback-only
products• Clock stability and signal stability needed tocapture signals with high fidelity for development• Multi-frequency, multi-constellation• Access to and replay of I/Q data files• Large storage capability

Defence
Leading defence agencies are utilising the GSS6450
for a number of reasons, including:• High dynamic range• Removable storage ideal for a secure labenvironment
Onboard spectrum analyser• Onboard spectrum analyser to ensure expensive
and hard-to-repeat test cases are occurring asplanned• High bandwidth for out-of-band and securesignals
