Deep Space Communication

What is Deep Space Communication ?

Deep Space Communication includes Communication with Satellites and Space-crafts active in the outer space region as well as collecting radio and Radar astronomy observations for the exploration of the Solar system and the Universe.

Functions of Deep Space CommunicationAcquire telemetry data from Space-crafts.Transmits commands to Space-crafts.Gather science data.Monitor and Control the performance of the Network.

History of Deep Space CommunicationThe First communication station was established at Holmdel, New Jersey (USA) in the year 1957.
