Sector satellites lite
Rethinking the "SectorSatellites" mod by iforgotmysocks, but only about ordinary and advanced satellites.
Deploying a satellite in a system would set up a trade subscription to all known friendly stations. Advanced satellites also periodically discover previously unknown stations in the sector.
PS: There are no new satellites in this mod (besides the ordinary and advanced satellites present in the game), which significantly reduces the load on the game engine.
