Accuracy and variations

Hi,

I wrote a simple library to interface a Listener through USB and displayed the data from UART in different formats. On plotting the data I obtained the following graph. The golden one is a tag fixed on a circular table and was rotated in a circular fashion.

The Red one is the sensor placed at one point and is in direct line of sight with the sensors.

Setup:

MDEK1001 devices.

4 Anchors and 2 Tags.

I have the following questions

  1. How can these values be smoothed out?
  2. Why do we have too much jitter in values?

Another attempt with noise reduction algorithm. Much better. The tags are stationary. I wonder why one tag has more drift than other.

Note: In legend, the tags with NR are with noise reduction applied
