- These "circles" on the map are usualy designating ground tracking/communications
- stations that the Orbiter can talk through. They are used as a second source of
- comm with MCC (Mission Control Center - Houston) to supplement the TDRSS meathod of
- comm. The "indications" are usually "name codes" and "frequencies".
