There are two overlapping questions, each with one or more good quality and well-received answer.
- Are there any CubeSats that have been launched into Geostationary (GEO/GSO) or Geostationary Transfer Orbit (GTO)? August 2017, has this good answer about future launches to GEO or GTO but no present satellites.
- Are there cubesats in GEO? June 2019, has this good answer demonstrating no current cubesats in GEO.
I wonder if this is a candidate for merging in order to make sure both good answers receive eyeballs? Or perhaps modifying the first (older) question to ask about future plans?
Right now I'd hate to close one as duplicate of the other because the answers are both good and deserve to be on non-closed questions.
