Abstract : Identifiers: Space communications. Contents: Orbital coverage a d satellite switching: Switching; Proof of existence of equal range sums; Relation between orbit configuration and system design. Lifetime of perturbed orbit ystem: Injection velocity errors, solar radiation pressure; Combined system lifetime. A system configuration: The global station network. Equipment pre-desig considerations: Modulation studies; Tracking and acquisition; Combination of communicating and tracking functions; typical frequency assignment of European A and B stations; typical operational performance including first and second acquisition mode. S YSTEM LOGIC AND CONTROL. Fr quency assignment considerations: Selection of frequency range; Number of frequency allocation channels; Frequency assignment. Identifiable problem areas requiring further work.
