@kenshirriff I'm fascinated by #9, which is right at the intersection of Honduras, Guatemala, and Belize. The nearest big city near the mark is San Pedro Sula, Honduras. But the closet *soviet-aligned* country would be Nicaragua, even though the mar is really too far west for that. But in 2017 ROSCOSMOS opened a GLOSNASS station in Laguna de Nejapa, Nicaragua, so its not impossible there was earlier coordination.
