GNSSBench

GNSSBench is a mobile + desktop app for engineers and integrators who need to validate GPS/GNSS modules fast, without building a custom test rig. It connects to modules over USB-serial or Bluetooth, records raw NMEA/UBX logs, and runs repeatable field test scripts (static, walk, drive, cold/warm/hot start). The app generates a clear report: TTFF distributions, fix stability, accuracy vs. ground truth, multipath sensitivity, dropout rate, and power-mode behavior. It also flags common integration mistakes (bad antenna placement, wrong baud, missing backup supply, poor sky view) with evidence from the logs. Exportable PDFs/CSVs make it usable for QA sign-off and supplier disputes. This is not a consumer navigation app; it’s a practical measurement and documentation tool for teams shipping hardware products that rely on GNSS.
