Thanks in advance for your thoughts
Phantom 3 Pro
Ipad
Litchi (newest firmware)
Clear day-flying LOS
IMU was updated prior to flight (in anticipation of possibly correcting the issue)
Waypoints are all set to an identical altitude 127'
This "bouncing" does NOT happen at a waypoint...
Issue
Part way through a Litchi flight (at the 2 minute 6 second mark), the P3P ascends and descends 3-5 feet (quickly) and repeats this numerous times during the mission.
Once this “bouncing” starts, it repeats (the increase and decrease in altitude) every 10 seconds (almost exactly).
Also at 2 minutes and 6 seconds, per airdata, the “sonar” kicks in, and gives errant altitude data…2- 3 feet and less, and this also captured in the airdata file.
During these intervals, the “real” altitude increases and decreases too.
As a band-aid, I just turned off the VPS, in hopes of stopping this problem, but wont be able to test it until the weekend,but that’s not really the answer for me..just a band-aid….
Can someone look into the Dat files…see if there’s something more definitive and solvable?
Here is a link to the airdata, DAT and short snippet of the video file….if you need anything else…let me know.
You can see the "bounce" on the video at the 6 seconds, 16 seconds, and 26 second mark

Also…its hard for me to know for sure which dat file is the correct one…there are creation dates, and modified dates….neither which match exactly the time stamp of the airdata file, so I have included both files I have for the day.
This is NOT the first time it has happened, and I believe it may be happening every flight…seems to happen only when moving…not hovering…but I haven’t confirmed that yet.
a very weird issue!
Thanks gentleman
