Loco accuracy
Posted: Thu Jan 09, 2020 12:14 pm
Hello.
I'm checking what is the highest accuracy I can achieve with 8 anchors in TWR mode.
At the moment the results aren't promising at all, the instructions said to expect up to 10cm of inaccuracy. But my results are worse.
The anchor positions are:
0 - (0, 3.6, 0)
1 - (0, 5.4, 1.52)
2 - (1.8, 8.4, 0.6)
3 - (6, 8.4, 1.52)
4 - (6.6, 4.8, 0.6)
5 - (6.6, 2.4, 1.52)
6 - (4.8, 0, 0.6)
7 - (1.8. 0.6, 1.52)
The points have a distance of at least 2 meters from each other, and yet this is the result I have achieved.

Those are 2 histograms are the errors. one of x and one of y.
I also seem to have an offset in the y-axis although when I stand in the same place the coordinated are almost 0,0,0 but when moving the offset appears.
I have another system that gives very accurate results up to 0.1 mm. After subtracting the Loco from my system I have achieved these histograms.
I searching for reasons why this could happen.
Moreover is there any way to increase the accuracy of the system by tweaking the settings?
Thanks in advance.
