Flight Log Analysis

Import, analysis, and plotting of telemetry logs

Flight logs for UAVs contain large amounts of data with many varying formats. Use the flight log analysis functions to load different telemetry log files including TLOG, ULOG, and custom file types. To extract and map signals from a telemetry log for generating plots, use the flightLogSignalMapping object. To analyze a log file and create a customized series of plots, use the Flight Log Analyzer app.

Apps

Flight Log Analyzer

Analyze UAV autopilot flight logs (Since R2020b)

Objects

`flightLogSignalMapping`	Visualize UAV flight logs (Since R2020b)

Featured Examples

Visualize and Play Back MAVLink Flight Log

Load a telemetry log (TLOG) containing MAVLink packets into MATLAB®. Details of the messages are extracted for plotting. Then, to simulate the flight again, the messages are republished over the MAVLink communication interface. This publishing mimics an unmanned aerial vehicle (UAV) executing the flight recorded in the tlog.

Flight Instrument Gauge Visualization for Drone

Import and visualize a drone flight log using 3-D animations and flight instrument gauges. This example obtains a high level overview of flight performance in MATLAB® using Flight Instruments functions in Aerospace Toolbox™. Then, to view signals in a custom interface in Simulink® , the example uses the Flight Instruments blocks from Aerospace Blockset™
