The NAUG network development will be based on the Open Systems Interconnection Reference Model (OSI-RM). The NAUG is the Nascom ground communications network being developed to accommodate the operational traffic of the mid-1990s and beyond. The NASA Communications (Nascom) Division of the Mission Operations and Data Systems Directorate (MO&DSD) is to undertake a major initiative to develop the Nascom Augmentation (NAUG) network to achieve its long-range service objectives for operational data transport to support the Space Station Freedom Program, the Earth Observing System (EOS), and other projects. The cultural challenges, however, have proven to be aĬhallenges of Integrating NASAs Space Communication Networks Each new requirement has made the networks more unique and harder to integrate. The differences across the networks have occurred in effort to satisfy their user missions' needs. The three distinct networks provide the same types of services, with customizable data rates, bandwidth, frequencies, and so forth. The technical challenges to integrating the networks are many, though not impossible to overcome. The existing networks are the progeny of the very first communication and tracking capabilities implemented by NASA and the Jet Propulsion Laboratory (JPL) more than 50 years ago and have been customized to the needs of their respective user mission base. The integration of multiple, legacy organizations and existing systems has challenges ranging from technical to cultural. The Space Communications and Navigation (SCaN) Program is pursuing integration of these networks and has performed a variety of architecture trade studies to determine what integration options would be the most effective in achieving a unified user mission support organization, and increase the use of common operational equipment and processes. NASA space communication services are provided by three separately designed, developed, maintained, and operated communications networks known as the Deep Space Network (DSN), Near Earth Network (NEN) and Space Network (SN). All industries experience the push to increase efficiency of their systems National Aeronautics and Space Administration ( NASA) and the commercial space industry are no different. Most often this is done with cost-reduction in mind, though ease of use for the customer is also a driver. Recent examples of this shift are changing to using robots in the assembly line construction of automobiles or the increasing use of robotics for medical procedures. The transition to new technology, innovative ideas, and resistance to change is something that every industry experiences. Challenges of Integrating NASA's Space Communications Networks
