[QUOTE="steeviebops, post: 1103873, member: 414368"] This might be an old thread but since it has been bumped I can contribute a bit! I'd say the reasoning for the specific positions is because of neighbouring allocations. For example, Arabsat were originally allocated 19°E in C-band, so Astra were slotted in at 19.2. Additionally, Kopernikus were allocated 28.5°E, which was taken over by Eutelsat, so Astra were assigned 28.2°E. The 28.2/28.5 split still exists today. This is probably true. There's two "libration points" at 105°W and 74°E where an uncontrolled satellite in geosynchronous orbit will drift towards and eventually settle at. [/QUOTE]
