Say there was a large reflective wall blocking 90 degrees of view horizontally and from horizon to 60 degrees vertically. It could be a building or rock face, or a stand of trees.
We already block signals bouncing up from below with the ground plane, but what about signals bouncing from the side? Is there a good way to block one side of a GNSS antenna?
Could they be absorbed, or deflected, or a combination of both?
Would a L-shaped ground plane do the job, or would it make it worse? Maybe it would need some precise tuning.
I believe you are correct @TB_RTK. Maybe in one circumstance it would not be true, and that is if there was no direct view from satellite to antenna, and only a reflected signal from that particular satellite would reach the antenna.
I was hoping to do it in a passive way as opposed to an active one though. In essence, I think a passive noise reduction like this would help Reach units fix quicker, more efficiently, with less processing overhead, and dare I say better accuracy? … but only for those situations with a stationary reflective object in view.
I have an idea that is not fully formed yet. Plus, I was hoping to there would be some other ideas out there that people might share.
