Hi, sorry for missing your post earlier. Have now set up emails for new posts.
The short answer is no, there is not a solution yet. There are a number of things that can be done, such as employing a gateway on the 'mothership' and routing all communications through this. Each sprite would use a low-power single block frequency to communicate with the gateway, which would then 'relay' the information to an Earth-based ground station.
That's one possibility. There are other scenarios. It depends on FCC, regulations, UK Space, etc and we are still working through these to get definitive guidance and authority on the requirement.
The positive takeaway is that there are options available to us, once we know what rules must be followed.
