To whom it may concern...
I have a question about the flight logs of the Inspire 1 UAV.
After downloading the on-board *.dat files, I discovered that I needed to run the file(s) through a convertor to change the file in question into a readable *.csv file. Once that task was completed, I opened the file in Microsoft Excel to look at the data. I do understand (for the most part) what I am looking at. The csv file sets up the way I expected it would. Data such as Latitude, Longitude, GPS Altitude, etc. comes in cleanly with the data points I would expect. I received 27 data fields with approximately 100,000 "records" for a flight approximately 10 minutes in length.
In reviewing the 27 data fields, I "discovered" some of the fields that I would expect to be included not to be present. Fields such as operational flight time (i.e. total seconds), battery discharge voltage (rates / duration / voltage / amperage draw), compass heading (0 to 360 degrees), etc.
Most of the data I received I understand. However, I do not know what "N Velocity", "E Velocity", and "D Velocity" represents; "QuaternionX", "QuaternionY", "QuaternionZ" represents; and “Sequence 135 Hz” (something at 135 hertz frequency?) represents.
Would someone be kind and explain the above data sets to me and explain where I can retrieve the other data that I am expecting to be present? Was my "missing data” not recorded? Was it lost in the file conversion? Are there more fields that are missing? Is it retrievable from my tablet (Crystal Sky) / account?
I am trying to understand and to set up the data for passing it through DashWare (or its equivalent). I would like to display telemetry such as altitude, direction, voltage, location, etc. on the videos for in-house training purposes.
Thank you for your time… I appreciate it… ========================================== JOHN TRACEY BENNETT PSO UAV Administrator Certified Pilot – sUAS (active) Chief Engineering Draftsman CAD Systems / Archive Systems Coordinator
