When flying a mission with my primary P4P, It went into Atti mode on its own around 36.6 seconds after take off at an altitude around 130 ft. I switched to my backup P4P and was able to complete the mission. I am attaching the CSV file from Air Data as a pdf file and the Google Maps depiction of the flight. I will attach both. I looked at it and it had 13 or more satellites connected the entire 34 seconds till the GPS came back. During the 34 seconds I switched out of P mode and back. I am not sure if this is what got the GPS to come back or it came back on its own. I am hoping that someone may be able to help me figure out what is causing it to go into Atti mode for that long. I wouldn't think it is an antenna connection or the GPS itself since it shows 13 or more satellites connected during the entire time. Thanks in advance for any help.
