I am a little confused at this point. Is the GPS drawn from the sensor file or from the telemetry file? It's not clear to me what kind of information the sensor files contain and how it can be displayed in the software. When opening the sensor file, I see a table of what looks like hexadecimal numbers.
In general, are you surprised that the 2.4GHz link was cut so quickly?
There is a setting in Q500log2kml to create a kml file from the Sensor file. It will be named with the same number and have the kml extension.
When you use the Convert button on the upper right of the program window it converts the Telemetry data to kml format. Both can be viewed in Google Earth and compared.
The camera link is 5.8 GHz WiFi and the control and telemetry link is 2.4 GHz radio. I was concerned at the short distance that the link appeared to be severed. 250 meters is not that far.
