Hi all. I am making software for the ground control and telemetry, which will be adapted for my flight platform. As the next automatic pilot will be Ardupilot Mega, I want to make the telemetry log to be compatible with the Ardu Mission Planner. The problem is what I cannot find any explicit documentation about the  Ardu Mission Planner output files. As I understand, there are two type of files: *.tlog and *.log. 

The *.log file is the ASCII text file downloaded from the hardware unit. It is "intuitive understandable" and has some documentation here (maybe in few days I could implement this protocol form in my solution), but my solution save the telemetry data stream, so maybe more interesting could be use the form of the *.tlog file, which is the telemetry stream too, but I cannot find any documentation about it fields meaning. I can not download any "official" *.tlog file. Some files comes with Mission Planner, so I can assume that *.tlog is a binary file contained literally all stream of telemetry communication (the same idea in my software). As binary file the *.tlog is not very readable by humans and data programs, but it is not a problem to write a converter (or, maybe, somebody have writtent one from *.tlog to *.log?). So the main question is: How to interpret (byte by byte) the *.tlog file?
