The interplanetary spacecraft Sakigake (formerly MS-T5), launched in January 1985, is a test spacecraft for the ISAS Planet-A mission, Halley's comet exploration, to be launched in August 1985. The design and the features of the communication system (CS) for Sakigake and Planet-A, and the on-orbit performance of the CS of Sakigake are presented, including diagrams illustrating the spacecraft and the CSs. The key on-board components that realize the successful communication are a high-gain antenna, highly sensitive receivers, a command demodulator using digital phase-lock loop, a high-power transmitter, and a data processing unit using a convolutional encoding with Viterbi decoding algorithm.
