SimIQI/Q CAPTURE & REPLAY
GNSS simulation with I/Q data files
Getting successful products to market demands precise, reliable, and flexible test capabilities. SimIQ
enables greater efficiency and consistency throughout the development cycle, delivering the exceptional
performance expected from our world-leading signal generation architecture.

Create I/Q data files withconfigurable sample rates
up to 120 Ms/s, and bitdepths up to 16

Generate high fidelity andaccuracy RF signals fromI/Q data files using Spirent
GSS7000 and GSS9000
Series GNSS simulators

Promote collaborationand consistency acrossbusinesses with multiple
sites, enabled by sharing
common I/Q files for testingSame hardware, greater capability
From the next generation of chipsets through to handsets and vehicles, bringing new products tomarket is a challenging process. Finding the balance between extensively testing and optimising, andtime-to-market, can be a risk-filled compromise.
SimIQ is a software solution that enables Spirent’s GSS7000 and GSS9000 Series simulators to capture,
replay and share I/Q data files without the need for additional hardware. This capability opens up
opportunities for testing receiver algorithms earlier in the development cycle, saving time and money
while delivering greater collaborative processes to global teams through simple sharing and consistent
playback.

Key applications
Testing GNSS software receivers
To cope with the demands of short product development timelines, developers are including virtual
testing in roadmaps. SimIQ enables validation of GNSS software receivers by injecting the generated
I/Q data, removing RF real-time constraints and allowing massive parallel simulation.
Validation of receiver algorithms
SimIQ enables developers and testers to validate models before the real hardware is introduced.
The efficient sharing of I/Q files means the same realistic scenarios can later be used to validate thehardware front end.
Injection of externals signals
SimIQ Replay generates RF including GNSS signals, custom waveforms, custom noise, and eveninterference and jamming events, helping users to navigate through growing GNSS vulnerabilities.
Generation of classified signals and codes from I/Q data
Approved users can now alleviate any potential security concerns by replaying confidential I/Q data files
with the same hardware used to test with civilian signals.
