I got 2 questions regarding precision which I have not seen answered anywhere:
Would it be possible to increase precision for TDoA systems if one would introduce several receivers (eg 3) per anchor location and average the results.
Has anyone tried this out and is this feasable or just a useless effort?
how reproducible are the results for one specific location? Meaning, if tag returns to the exact same location what precision can I expect?
Thanks in advance for your inputs.
thanks for the quick reply.
One additional question:
You write: “It would help if done correctly. But putting 3 antennas next to each other will cause them have an impact on each other which could change the results.”
Is this also there case in a TDoA situation where just the tag is sending a point and anchor antennas just need to receive this ping?
Thank you and best regards
I don’t pretend to be an RF engineer but from my understanding yes. If nothing else they are metallic elements close to the antenna, that can change the gain pattern of the antenna.
How much impact this would have I have no idea.
Thank you Andy. Your info cover me a idea.
