【 摘 要 】

The next generation Earth observing satellites will face challenges in supporting high rate space communications from the increasingly sophisticated instruments. Emerging applications will need space-to-ground links with data rates forecasted to be in the 1-20 Gbps range. To meet these challenges, NASA is designing and integrating a 26 GHz Polar Subnet to support space communication needs in 2020 and beyond. This paper describes the current effort of the Space Communications and Navigation Program's Near Earth Network (NEN), managed out of Goddard Space Flight Facility (GSFC), to deploy a 26 GHz Polar Subnet including the implementation, topology, capabilities, architecture design, operations and key design trades.
