I have following querry

  1. what is the convention of PDOA and PAOA (which side is positive and negative) ?
  2. Why there is difference between PDOA and PAOA readings are they are two methods of calculation of AOA or just a transform ? PAOA offset is 0 in my case
  3. Why is there so much fluctuation in readings even though the device is close apart and NLOS is aprox 0 ?
  4. Any performance parameter that needs to be tuned to get a better/ accurate readings from the device.?

Thanks for all your help and support.
