Drone Flight Report / PX4 .ulg Viewer (Online ULog Analysis)

PX4 .ulg Viewer (Online ULog Analysis)

PX4 stores flight data as ULog files. They contain a lot of useful information, but reading them usually means installing QGroundControl or running the PX4 Flight Review stack. This viewer gives pilots a faster path to the essentials.

What is extracted

• GPS latitude, longitude and altitude
• Local position and velocity where logged
• Battery and flight-mode context, when available
• The log's own wind estimate, if the flight recorded one
• Timing information for elapsed flight time

How to get the .ulg file

Open QGroundControl, connect the flight controller, go to Analyze Tools → Log Download, select the flight and download the .ulg file. You can also copy it from the SD card's /log directory.

What the report includes

A satellite map with the flight path, start and end markers, distance and altitude statistics, a regional wind reference, a health check and a downloadable PDF.
