I’m planning to a locationing system development.
I’ve tested DWM1001 and TWR already, let me ask about TDoA and PDoA.
My understanding is:
- For TDoA, the distances of rx nodes are longer is better for accuracy and ideally tx tag shall be inside of envelope of rx nodes.
- For PDoA, the distance between antennas shouldn’t too long and ideally it shall be less than one or half frequency * light speed (2-4cm).
Is my understanding OK?
