Hi,

Can 4 Lighthouse basestations 2.0 cover a 4x20 meter area, and if so, how should the base stations be laid out?

Hello. As stated here, 4 base stations can cover around 8x8x3 meters of flying space. With a maximum range of 6 meters and an horizontal view angle of 150°, you can cover the whole 4x20 meter area as shown in the image below. However, this remains highly untested, as there are several areas covered by only 1 base station. Also, note that for the geometry estimation performed in the cfclient, there should be an overlap of the base stations.

Hello!
So the Lighthouse deck only works with up to 4 visible base stations at a time, if more than 4 base stations are used they must be set up in such a way that this condition is met. There is a guide here for setting a larger system but the process becomes more complex.

Hello!
I can recompile the firmware, add to 6 base stations, but how to calibrate the base station's position and get the geometry of the relative position of all base stations ?

[bitdeckai]

if increase the number of base stations to 6 or 8, similar to the videos of the two base stations below, Can you provide a video as reference?

Hello!
Each base station's calibration data describes slight imperfections in the the manufacturing. The calibration data is measured in the factory and is stored in each base station, meaning that you do not have to worry about it. (Lighthouse system overview)
The geometry estimation is normally obtained in the cfclient by following the wizard. However, the client does not support more than 4 base stations at a time. I would suggest to separate your base stations in smaller groups, get each one's geometry estimation through the client and then add all the geometry estimations in the same configuration.
I will try to find out some other solutions and will keep you updated.
Unfortunately, due to limited time we can't provide a video right now but let us know if you have some specific questions.

I am very much looking forward to your follow-up updates. We have a lot of positioning requirements for more than 4 base stations. Can you also support 16 base stations?
