The data are extracted from either the onboard .DAT files or the device .txt logs using DatCon (for DAT files) or the PhantomHelp / AirData websites for basic fields from the .txt logs. For more detailed output from the .txt logs I use TXTlogToCSVtool.
Then you need a data analysis package to analyze and visualize the data; I use Wavemetrics Igor Pro, but you could equally well use MatLab or similar.
Alternatively, you can skip all that and use @BudWalker's CsvView for DAT files and .txt logs, which uses a different approach to data visualization by creating "players" but works very well.
I copied the above post from a thread about a lost drone and reading “data files” and interpreting what was the cause. Ocean Crash – Resolved #47
I am a newbie to drones and RC flying. I have roughly 2.5 hours flight time. I have done a LOT of reading and a lot of reference is made to the data files and seeing what went on during the flight. In my spare time I would like to learn the basics and what tools to use. I hope that is a reasonable goal. I parsed the above thread and used google to search for information.
Directions on finding flight logs for Apple & Android can be found in this thread
Could I get some direction on which files to analyze and which tools to use. Pros & Cons of the tools.
