PX4 flight logs
Connects todayThe ULog files a PX4 vehicle writes for every flight.
Files & logs · File
Import a .ulg into a source you already have. Its logged fields land as history you can chart beside everything else on that machine.
What Plexus reads
- Logged fields and their units, straight out of the file
What it does not read
- Anything live. A log is a record of a flight that has already happened
- It is not a connection of its own — the file imports into an existing source
Connecting it

Tutorial
Visualize PX4 ULog flight logs in the browser
Import a .ulg file into Plexus and chart any logged field. No install, no scripts.
- 1
Get the log. PX4 writes a .ulg for each flight to the SD card, under log/. Or download it over the link with QGroundControl: Analyze Tools, then Log Download.
- 2
Open the source for the vehicle in Plexus and click Import data. If the vehicle isn't in Plexus yet, add it first.
- 3
Drop in the .ulg, up to 200 MB.
- 4
Pick the fields to import. Each shows its point count and range, and the filter box narrows the list.
- 5
Leave "Save imported range as a run" on and name the flight, then click Import.
What you’ll see: The fields land as history on that vehicle, with their original timestamps, taken from GPS when the log has it. The flight is saved as a run you can compare against other flights.
Connect it, and the dashboards build themselves from the first data that lands.
