Reference Satellites and Formation Flying
The Reference page of a satellite's basic properties is apparent if you are licensed for STK Astrogator or STK Premium Satellite capabilities. The page enables you to specify a vehicle to be used as a reference vehicle in a formation flying situation with other satellites. In target/chase terminology, this is what is known as the 'target' satellite. Simply open the Reference page for each satellite in the formation, select the desired reference vehicle in the list of reference vehicles and click OK or Apply.
