This payload architecture enables single-hop, low-latency, full-meshed, user terminal to user terminal connectivity by avoiding double hops to a central hub. Delivery of services to users is provided via low-cost, small-aperture terminals (e.g., 1W HPA and ;m antenna). SPACEWAY® satellite supports a peak capacity of 10 Gbps of raw user data.

NASA Lewis Research Center is developing an on-board information switching processor for a multichannel communications signal processing satellite.
The information switching processor is a flexible, high-throughput, fault tolerant, on-board baseband packet switch used to route user data among user ground terminals. NASA Lewis Research Center is developing an on-board information switching processor for a multichannel communications signal processing satellite.
The information switching processor is a flexible, high-throughput, fault tolerant, on-board baseband packet switch used to route user data among user ground : Jorge A. Quintana and Mary JO Shalkhauser. It describes alternate switching concepts, i.e., circuit switching and fast packet switching, their advantages and shortcomings, and potential applications for future commercial satellite communications.
In particular, fast packet switching is a relatively new concept for on‐board applications and shows a great promise for the integrated operation of digital satellite by: 4. An ATM‐based on‐board switch with a shared bus architecture is described. This switch is suitable for a satellite system with medium throughput requirements.
The development of components and technologies for high capacity switches with a throughput of 5–10 Gbit/s, within a German technology development programme is by: 5.
The NASA Lewis Research Center is developing a multichannel communication signal processing satellite (MCSPS) system which will provide low data rate, direct to user, commercial communications services.
The focus of current space segment developments is a flexible, high-throughput, fault tolerant onboard information switching processor. This Cited by: 2. Potential satellite applications, alternate satellite network architectures, system design issues, and onboard switching/processing options for satellite B-ISDN services are investigated.
Special attention is focused on fast packet switching architectures and switch design details to exploit the feasibility of implementing a fast packet switch in the future advanced communications satellite.

The satellites implemented for the BSS are often called direct broadcast satellites (DBSs). The TVROs needed for BSS reception should be smaller than the ones needed for operation in the FSS.
The direct reception shall encompass both individual reception (DTH) and community reception File Size: 9MB. The architecture of a microprocessor-based packet switch using three processors for use on-board satellites is presented. The operation of the switch involves three distinct functions, namely, the input, the routing and the output functions.
Each of these functions is performed by one of the three microprocessors. control facilities that control and monitor the satellites. To make a telephone call, send an e-mail, broadcast TV programs, or exchange other information, a user on the ground generates the information and sends it to a satellite through a communication device either directly or via a ground station.
Communications satellite service providers, acutely aware of their need to remain competitive with terrestrial alternatives, have embraced payload technologies promising to lower their costs of service. Multi-Beam Antennas (MBAs), Digital Channelizers (DCs), Digital Channelizer Beamformers (DCBs) and even Fully Regenerative Processors (FRPs which demodulate, decode, packet switch.
