Help with Stability Issues in Lighthouse Positioning System

[dakeprithvi]

Hi!,

We recently transitioned to the new Lighthouse positioning system. While most forum discussions suggest the basestation can capture a volume of up to 5x5x2 meters, we are working in a smaller space (3x2x2 meters).

Here’s our setup:

• Basestations:
  Mounted on tripods at two corners of the side parallel to the y-axis, angled downwards at 45 degrees.
  Within the 3x2x2 volume.
• Observations:
  This arrangement provided the most stable results compared to other setups (e.g., diagonal placements).
  However, the area of stable operation appears much smaller than 3x2x2.
  If the drone moves ~0.5 meters away from the origin, it sways significantly and crashes.
  Within the 3x2x2, there are also signal drops in certain spots during geometry estimation.

Here's a video highlighting the issue: Video link. Timestamps 0:25 and 0:35 seconds (sway before we ask it to go back to origin).

Despite trying multiple geometry setups, the current arrangement gives the best results, but it’s still far from what we need.

Could anyone help explain:

• Why signal loss occurs even within the 3x2x2 space? (We took care to put window blinds to prevent sunlight)
• Any advice on resolving these issues or improving the setup? (Tried multiple setups, with more height > 3 m, still no results)

Thanks in advance for any insights or suggestions!
