Trimble® engineers drove 3,000 km from Munich to Norway’s Jammertest 2024, testing GNSS engines against jamming, spoofing and meaconing in tunnels, urban canyons, and Arctic conditions. This eBook details centimeter-level accuracy stats, tunnel dead reckoning recovery and ionospheric mitigation.
In this eBook, you will learn how to:
- Maintain 95th percentile horizontal accuracy under 0.15m across 2,641 km drives with RTX corrections, even in VRS network switches
- Recover centimeter-level positioning 15 seconds after 8-km tunnels using tightly coupled GNSS-INS dead reckoning
- Detect and suppress spoofed signals on GNSS receivers, prioritizing integrity over false continuity
- Mitigate solar storm ionospheric effects with Trimble® IonoGuard
technology, cutting navigation errors by over 5x during aurora tests - Benchmark anti-jamming performance at Jammertest against competitors under 200W interference scenarios
