I am working with the Tracker One & Tracker One SoM Eval board. I have successfully parsed the “loc” event. I would like to understand how the “hd” heading variable is calculated.
Is it derived from the IMU? or is it calculated from past GPS locations?
Does the mounting orientation of the Tracker One / Eval board matter to get a proper reading? In what orientation should the device be pointing to read 0 (North)?
I have a Tracker One / Tracker SOM Eval board sitting side by side, however they are reporting significantly different values.
Any insight is appreciated.
