LOG ANALYSIS
Decode the black box. Learn how to interpret DataFlash binary logs, diagnose vibration issues, investigate crashes, and analyze power consumption.
Log Analysis
DataFlash Structure
ArduPilot logs are **self-describing binary files**. They do not require a separate schema file to decode. The first few kilobytes of every `.bin` ...
EKF Innovations & Lane Switching
The Extended Kalman Filter (EKF) is the brain of the autopilot. It fuses data from IMUs, GPS, Compass, and Barometer to estimate position and attit...
Vibration Analysis & FFT
Vibration is the root cause of many flight issues, from "Jello" video to EKF Lane Switching and even flyaways. ArduPilot provides two powerful tool...
Power Forensics
Power failure is the most common cause of non-pilot-error crashes. Analyzing power logs allows you to distinguish between **Battery Exhaustion** (r...
Watchdog & System Faults
When the autopilot reboots unexpectedly or disarms mid-air, the **Watchdog** and **Fault** logs are the first place to look. These logs capture the...
