PNT / GNSS Testing
Stress every receiver, sensor-fusion stack and timing node—before inaccurate data leaves the lab.
Why Positioning-System Testing Matters
Sat-nav chips now track four constellations, multiple frequencies and spoof-proof signals (Galileo OSNMA, GPS L5). Add urban canyons, space radiation — or a cyber-attacker’s spoofing device — and position errors jump from centimeters to tens of metres. Regulations for drones, autonomous cars and critical-infrastructure timing grow tougher each year. Spirent’s PNT simulators let you replay every sky view, jamming pulse and spoofing attack inside the lab, so bad data never reaches the field.
