I am very surprised that a commercial organization that is not following IARU regulations is now requesting the help of Amateur Radio enthusiasts.
Reading up on the technology you are developing, it seems you want to relay AIS (VHF) transmissions into frequency space (435.800) that you are not allowed to use.
If the next flight of one of your satellites is part of an university project, I will happy to support it in any way, but not when it is part of commercial activities, then you’ll need to use other frequencies.
With regards,
