Hi,

I am performing a little research on GNSS patch antennas on satellite and the way their radiation pattern could be affected due to close object such as parabolic telecom antenna, or solar pannel.
Then, because of this attenuation, a link could be made with lack of precision on localization computing on earth.

As I am struggling to find documentation relating accurate theory about this phenomenon, I come here to know if any reader would know such documents that I could use to pursue my study?

Thank you very much for any reply and have a nice day

The antenna designer on the satellite should have considered this. It is not likely the direction of the patch antenna (towards earth) should be obscured by a solar panel (towards the sun). That would be poor design.

Hello,
Indeed, I totally agree on this point.
However, my study deals with GNSS integration on geostationnary earth orbit or high earth orbit which are satellites usually crowded with moving telecommunication dish antennas with great reflector. These moving parts could, in some cases, create signal reflection toward the GNSS antenna.

The point of this GNSS integration on these satellites is to enhance the quality of satellite position computation while being placed on orbit.

Best regards
