I just tried to get the data from the recorded VIRB camera. I was succesful in reading the GPS data. But I am missing the HDOP (or estimated position error). Is this data just not delivered or how can I get this?
Secondly I didn't find anything that gives me the air pressure from the file. There is only a field 'improved Elevation' -> is this somehow derived from the GPS elevation and Air pressure?
The documentation does not go into details how to decode the data, or do I just miss some important document from the documentation?
Also a good way, how to calculate from the gyro/accelerator the values is missing????
Thanks for any help and/or forwarding to a more specific documentation.
