Combined spectral management/ satellite receiver modem

Satellite transponder bandwidth cost has always been expensive, and more efficient use of this scarce asset is highly desirable. Operators around the world are demanding smarter satellite systems capable of optimized dynamic bandwidth allocation through Bandwidth-on-Demand (BoD) and Quality of Service (QoS) as well cost effective end-user terminals and ground stations based on commercial standards to benefit from global economies of scale. Conventional analog system implementations have many performance limitations that include frequency dependency, non-linearities, high insertion losses, circuit tuning requirements and expensive waveguide inter-connections that ultimately limit the performance of the complete receiver system. These limitations are greatly multiplied when operational scenarios require multiple frequency and channel configurations.Solving these problems requires extension of digital processing to the traditionally analog RF domain. Superconductor electronics allow for direct-conversion system approach has been realized with Digital-RF architecture. This architecture enables digital signal distribution system and can provide multiple band operation within a single integrated system. Here are we are proposing a single software defined receiver system that can be used to monitor satellite operations and also act as a multi-band terminal and intruder detection.
