Satellite network capacity, adaptability, and responsiveness are enhanced with onboard capabilities for packet switching, bandwidth allocation, and spot-beams which facilitate uplink and downlink spectral reuse. A recent over-the-air (OTA) test of the SPACEWAYTM (TM) system, a Ka-band regenerative satellite mesh network supporting IP packet services, provides definitive demonstration of key capabilities in the areas of quality-of-service, routing for unicast and multicast (both best-effort and guaranteed service) traffic, dynamic bandwidth resource allocation, security, and configurable satellite uplink and downlink components. Leveraging SPACEWAY system technologies and operational capabilities serves as a pragmatic step toward the development of future multi-satellite networks with more advanced features including onboard packet routing, multi-mode radio transmission, and inter-satellite links, which are now being considered for transformational satellite networks.

Rajeev Gopal received a Ph.D. in Computer Science from Vanderbilt University and a B.E. in Electrical Engineering from BITS, Pilani. He has worked in satellite network development, computing research, biomedical R&D, and large scale information systems. Dr. Gopal was one of the SPACEWAY system architects and the chief architect for the SPACEWAY Network Operations Control Center development. Currently he is involved in the Transformational Communications Satellite (TSAT) System project.
