Telecommunications systems are indispensable to control spacecraft and gather telemetry data from space. After the launch of each spacecraft, the telecommunications systems worked well and supported the observation around the encounters with Halley's comet. The system performances have been confirmed to be coincident with the design through operations. This chapter describes the design principle and constitution of the telecommunications systems, and the operational results together with system evaluations.
