MDEK1001 Capabilities

I’m interested in learning more about the possibilities of this system.

  1. The documentation often talks about indoor usage. What problems occur when you operate it outdoors in an open line-of-sight environment?

  2. What are some techniques to improve the accuracy beyond 10cm if at all possible? i.e. can you get to sub cm accuracy doing things like taking more samples, using more anchors, etc.

  3. Can you perform any form of 3D localization (your docs talk about just x-y)?

  4. If you had a 60m x 60m open space and you had anchors at the corners, could you locate a tag somewhere in the middle? Is the reported 60m range strong enough? What accuracy would you produce at this range?

  5. The diagrams typically show the anchors in a circumference configuration with tags placed in the middle of the polygon area. Could you place most if not all of the anchors in an area less than half a meter and produce any type of accurate localization with the tags meters away from the group of anchors?

Hi Stephen,

1: FCC and ETSI regulations make it challenging to support outdoor usage. Fixed infrastructure is not allowed which mostly prevents deploying CH5 anchors outdoor.

2: There are some good posts on this forum which discuss this topic in details

3: Z is not as accurate as our x/y performance. Placing Anchors in lower and higher positions will help, but lower anchors will be affected by NLOS.

4: 60m will not work reliably. The max is in the region of 25m.

5: Short answer - no. Remember this is trilateration. PANS will track tags outside of the polygon but not when the anchors are lumped close together like you describe.
