![]() Here is a brief discussion of the seven DSN data types that are processed in the UPL and DTT:Īny computer system, whether desktop or supercomputer, has an internal clock that directs every step of the computer's operations. Today, thanks to the Network Simplification Program, these have been consolidated into two DSN systems: Uplink (The Uplink Tracking and Command Subsystem, UPL) and Downlink (The Downlink Tracking & Telemetry Subsystem, DTT). In the past, each of these seven data types was associated with a separate DSN system. The DSN is an extremely complex facility, but it becomes more easily comprehensible if you recognize its seven data types, as a context for learning about DSN subsystems, and how they relate to each other. Each image, when selected, displays an extensive caption describing a part of the DSN's history. The DSN enjoys a rich history that is closely intertwined with the history of the space age and the cutting edge of development in telecommunications technology. The strategic placement of the DSCCs permits constant observation of spacecraft on interplanetary missions as the Earth rotates. The Network Operations Control Center, NOCC, is in building 230 at JPL. It consists of three deep-space communications complexes, DSCCs, placed approximately 120 degrees apart around the world: at Goldstone near Barstow in California's Mojave Desert at Robledo near Madrid, Spain and at Tidbinbilla near Canberra, Australia. The DSN is the largest and most sensitive scientific telecommunications system in the world. The DSN also supports selected Earth-orbiting missions. Radar astronomy, and related observations for the exploration of the solar system and the universe. The DSN supports interplanetary spacecraft missions, radio astronomy, ![]() The NASA Deep Space Network, DSN, is an international network of facilities managed and operated by JPL's Interplanetary Network Directorate, IND. You will be able to describe advantages of arraying and cite planned improvements in the DSN. You will be able to describe the three Deep Space Communications Complexes, and compare five types of Deep Space Stations. Objectives: Upon completion of this chapter, you will be able to describe the Deep Space Network's seven data types and trace data flow.
