Use Z to improve X and Y accuracy

We currently have a system of 11 anchors and a single listener setup with 20-30 tags for position measurement. We would like to improve the accuracy of the system and we know that the Z heights do not change for our tags, making this measurement redundant. Using our current setup is it possible to use the Z ranging data to improve the accuracy of our X and Y measurements?

I’m assuming that this would involve writing a custom ranging algorithm as the listener doesn’t return the anchor ranging data from each tag, only X, Y and Z? Has a “2D mode” like this already been implemented before?

Hi Nick,

what you can do is to write an User Application for the Tags using PANS library.
The application will receive the ranging data and a custom Location engine can be implemented. The calculated location can be then sent via IoT data to the server.
