This is a screenshot from a flight log of mine. I am in the latest beta firmware of Android.
Looks identical to OP's video. No idea what the bars are for.
I beg forgiveness. My bad... As a new EVO owner I'm still
frequently referencing the PDF manuals for the drone and the Explorer app. And in my haste I went straight to the Explorer manual for a reference of screen displays instead of booting the tablet and app. What I found on Page 7 was a "modified" display of what is represented in the Flight Log display that OP and you have posted. What confused me was the Flight Log display shows a single line of flight data whereas the manual was showing the telemetry with a dropdown second line of information. I was trying to find some details on the bar graph next to the Flight Log GPS satellite counts. The dropdown line during real time flying shows RC signal strength and Image Tranx strength and the icon for Satellites but in that line there is no bar graph. So I've dug a little deeper.
the drone was originally purchased through the autel dealer in Queensland Australia, April this year
@Barney Let's look into some additional details that might lead to a new revelation and then again maybe a dead end. Note that as you view your running Flight Log video, pay attention to the bar graph next to the GPS satellite counts in the top line. That bar graph is actually representing the overall signal strength your Drone is receiving from the satelliltes. As as you can see, for a large portion of your flight time from launch to lost you were not showing any bar strength. That is a "strange" phenomena if you ask me.
So I checked the manual and it says that if the GPS satellite link is lost the Failsafe will initiate a LAND ONSITE three seconds after the satellite loss. The lack of any strength during most of your flight is suspicious and needs further investigation. I looked over some of my own recent flight logs and they show
22 to 24 satellites AND a solid 3 bars of signal strength for the duration of each flight. And I am much further North on Earth than you down under are South towards your pole. So I don't see why your satellite coverage should be weaker than my high latitude location.
You say you have owned the EVO for four months. So I will speculate you have accumulated quite a few FLIGHT LOGS going back to your first days of ownership.....I hope. Let's review one of the earliest Flight Logs you have on record and observe how many satellites you were locked onto and also what your bar graph signal strength was during the flights.
What I'm hoping to discover is your drone was receiving good signals and satellite counts as a brand new bird. And that will be much different than the latest flight log data. This would indicate that the Drone may have experienced a problem in the GPS antenna system in the unit and that caused a Failsafe event to initiate and the lost drone.
Another request....you said you had flown this lake mission 40+ times. Hopefully you have those logs too. Look them over and see what the Satellite count and signal strength was on those first flights in this area. It would be a smoking gun if those early flights showed good reception in the same area where the drone was now lost. Again a finger pointing to a failure of something within the drone internal GPS antenna and at 4 months old it should be covered under warranty.
Don't skimp on the details when you report back. LOL Maybe we will get lucky!
Oh I just love a good mystery! The calling I never pursued was as a forensic investigator~!
