Hello,

I and my friend were using our DJI Mavic Pro on the beach and the weather was nice, no wind. Suddenly our two Mavic Pro lost GPS from 15 satellites to 0. It was crazy and so hard to control it. Finally I managed to land my drone ATT mode but unfortunatelly my friends drone was lost on the sea.

What was the wrong ? Jammer ?

This is my log. Please have a look and comment on this.

Thank you so much.

Hi there, I am sorry to hear about the issue. May I confirm if this issue happened in this specific place only? I'd suggest that you try to fly in a different place and check if the issue exists again, please kindly keep us updated about the result.
I am sorry for your friend's loss, if his drone is within the warranty period, please help to ask him to contact our support at http://www.dji.com/support, we'll help to arrange data analysis for the accident. Thank you.

Hello,
Thank you for your reply. It was the first time to lose all signal. We were sitting together with my friend and we were using our own drones. The area is near the Bosphorus/ISTANBUL and drones were on the sea. The place is like a small village.

My friend's drone is not within the warranty period. Could you analyse my logs and say what was the wrong ?
Thank you.

I am sorry again for the issue. For your friend's drone, if it is out of warranty period, it may need to pay for data analysis. If needed to proceed, please also contact our support at the link above for further followup. Thank you for your understanding.
