Turn a drone flight log into an interactive 3D replay

RavnView replays ArduPilot dataflash, PX4 ULog, MAVLink telemetry, DJI Fly and GPX flight logs over real 3D terrain with synchronized onboard video.

Drone flight log analysis

Review aircraft position, altitude, speed, battery, control inputs, weather and detected events. Explore charts, ask an AI assistant questions grounded in the telemetry, and export PDF, CSV and KML reports.

Supported flight log formats

• .BIN — ArduPilot log viewer
• .ULG — PX4 log viewer
• .TLOG — MAVLink log viewer
• .TXT — DJI Fly log viewer
• .GPX — GPS track log viewer

How it works

1. Upload a log — Drop in a dataflash .bin, ULog, tlog, DJI Fly record, or GPX — with the onboard video if you have it. Or connect DJI Cloud and pull your fleet's flights in.
2. Watch the replay — A deterministic 3D reconstruction driven entirely by your telemetry — never a physics guess — with full HUD chrome and switchable cameras.
3. Analyze & share — Chart any logged parameter, ask the AI assistant what happened, export a report, and share the flight with a public link.

What you get

• Every major log format — Per-format parsing for ArduPilot dataflash, PX4 ULog, MAVLink telemetry, DJI Fly flight records, and plain GPX tracks.
• FPV cockpit view — Switchable cameras including a cockpit view with attitude indicator, compass strip, altitude tape, and rotating minimap.
• AI flight assistant — Ask questions about a flight in plain language — answers grounded in your own telemetry, plus narrated event commentary.
• Charts & exports — Chart any logged parameter against the replay clock and export PDF reports, CSV data, and KML tracks.
• Private by default — Flights live in your own library. Make one public and anyone can watch the replay at its link — no account needed.
• A real flight library — Rename, organize, and revisit every flight, with a live storage meter against your plan's quota.
• 3D terrain replay — Your aircraft re-flies the recorded track over real CesiumJS terrain — propellers spinning at the actual logged motor outputs.
• Synced onboard video — The flight video rides along as picture-in-picture, locked to the replay clock frame by frame.
• AI event commentary — Mode changes, battery sag, GPS glitches — narrated as they happen on the timeline.
• Analysis drawer — Charts, the event table, and the flight report stay synchronized with the moment you're watching.
