Hi,
In the past....the CSV file from PhantomHelp did shows the VPS height data when not measuring (out of range or simply not able to determine height) as an empty cell.
But not in the latest CSV files for (i think) FlyApp drones.
For the pilots on this forum who like to analyze logs, latest PH CSV files could be wrongly interpreteted. (well that is my opinion...)
To make this clear watch the video, flyning low over water.
In the video you will see the VPS height in the Flyapp showing in red or amber, but not always.
When it is not seen, it is not able to measure height. BUT in the CSV this is not seen, as data is copy paste from the last measured height.
Data examples as screen shot:
VPSsensor1 : from FRAP (data from the flight in the video). I colour VPS copy paste data in red, like 2!2
VPSsensor2 : same data in the CSV, see column "OSD.vpsHeight [m]" ; each cell has data....
VPSsensor3 : same flight and CSV ; ascending/descending to > 100 baro height and see that the VPSheight is there, in each record 5.1 until measuring again!
VPSsensor4 : old CSV flight ; as said, in previous PhantomHellp versions (and perhaps still like this on older type drones) the value = empty = not measuring / out of range
The column "OSD.isSwaveWork" is usefull : not able to measure * height = FALSE.
* out of range ofcourse or surface below is not 'good' to make a measurement (see the manual).
imo OSD.isSwaveWork should be renamed to OSD.isVPSheightMeasuring... ;-)
cheers
