GNSSWatch

GNSSWatch is a mobile + web app for teams using GPS modules (fleet trackers, asset beacons, drones, marine units) that need to detect spoofing, jamming, and bad-fix conditions in the real world. It ingests NMEA/UBX logs from devices (via BLE, USB, or uploaded files) and continuously scores signal integrity using simple, explainable checks: sudden time jumps, impossible acceleration, satellite constellation anomalies, C/N0 drops, and location divergence vs. inertial/odometry when available. The app generates incident timelines, heatmaps of interference hotspots, and “proof packs” (exportable reports) for ops teams, insurers, or compliance. It’s not a magic shield: it won’t stop RF attacks, but it will shorten time-to-diagnosis and reduce costly false assumptions (device failure vs. interference vs. spoofing). Designed for field techs: quick capture, offline mode, and one-tap sharing to engineering.
