NASA's Long-distance Operator Modernizing Aging Dish Network

摘要

As NASA pushes ahead with plans to modernize its space telecommunications systems -elements of which have not been updated since the 1980s - the agency also expects to stand up by 2018 a next-generation data network that will consolidate current space and ground assets with new technologies into a single, unified architecture in support of future exploration missions.rnManaged by the Space Communications and Navigation Office (SCaN), NASA's communications infrastructure comprises a global patchwork of ground stations, low-Earth-orbiting spacecraft and deep space probes that provide the backbone of data-relay services for communication among NASA and other federal government agencies active in space.
