Reply to comment by [deleted] in China looked at putting a monitoring satellite in retrograde geostationary orbit via the moon by OkOrdinary5299

Well above or below wouldn't work. If you mean further out then that'd be a bad idea since that's where most graveyard orbits are and if you mean closer in then sure that's possible but positions of GEO satellites do not require space-based detection. There is really no point in doing this unless you were operating like gssap

Above as in higher altitude, not a different inclination. If space based detection isn't necessarily, why does the US do it?

"More accurate tracking and characterization of man-made orbiting objects." You can do a lot more at ~0 relative velocity versus ~6 kps though

Not necessarily. Taking multiple measurements from different angles can be more useful than sitting still and staring at it all day.

RPO is not a static operation Edit: to expand, that article you sent says that gssap conducts RPO meaning it moves along the belt as you mentioned. Since it is so close it can actually look from more angles in a safer manner than a retro orbit
