Reliability-based TT&C subsystem design methodology for complex spacecraft missions

Architectural optimization of spacecraft telemetry, tracking and command (TT&C) subsystems, in the view of reliability analysis is discussed in this paper. Subsystem equipment configuration is optimized using an autonomous design approach, which satisfies the system performance parameters such as multipath loss, uplink C/No, noise temperature, telemetry EIRP etc. This leads to reduced costs of spacecraft manufacturing and launching.
