European Urban Canyon: LiDAR-Aided GNSS/INS Post-Processing
Historic European ‘urban canyons’ – narrow, 3–4 m streets flanked by 10 m facades – can mask GNSS like glassy CBDs, but with different multipath.

Forest Canopy: Reliable GNSS/INS Post-Processing
Dense forest is tougher on GNSS than it looks: canopy blocks most signals, and the few you keep line up along the road – so lateral geometry gets weak.

Underpasses: GNSS/INS Post-Processing That Holds Fix
Underpasses cause full satellite loss for a second or two – enough to break many RTK solutions. With tightly-coupled Network-PPK, forward/backward ambiguity fixing, and dynamic pivot switching, AlgoNav holds or rapidly re-locks fix.
