Data Logs

Data Logging

Your flight data will be logged in 2 different places during your flight:

1. Dataflash logs (onboard pixhawk) - These will contain the most amount of information during the flight as all the data is logged at a much higher rate than what comes down to the ground.

• In order to view these logs, you will need to pull them off the SD card
• Here are several ways for you to analyze the data flash logs
• These logs can be converted to CSV files using a python script
• There is a function available for converting these logs to matlab, but in the past I have found it to be a little unreliable. I have had much better luck using Matlabs tdfread function for importing the csv file.

2. Telemetry logs (onboard ground station) - These are logs generate by QGroundControl that log the data coming down from the pixhawk at a much lower rate than above.

• These logs can be read by QGroundControl in a playback mode in order for you to watch your flight on the ground station software after your flight is finished
