The new S-A6640 is a managed Ethernet Switch/Router with 12x1GE copper ports and uses IP and Ethernet protocols to help significantly improve communication speeds, while lowering costs and significantly improving time-to-market for small satellite constellations as well as manned missions.
Communication Hub of the Space Digital Backbone (DBB)
Designed with major components with a radiation pedigree, the S-A6640 can be easily installed in any NEO or LEO space mission with any target platform size and significantly lowers the risk of communication-related failures in space.
In addition to serving as the centerpiece of the Aitech Space Digital Backbone (DBB) architecture for LEO/NEO applications, the new switch operates as the main connectivity hub for any small satellite or human rated space mission, operating as a scalable network architecture for all on board computing and communication equipment.
Alex Trigoub, space product line manager for Aitech, noted: “Compared to other protocols, such as 1553B, Serial and SpaceWire, Ethernet provides a much higher bandwidth and far more flexibility in a wide variety of applications. It also provides its own mechanisms for protection and redundancy, including xSTP & VRRP, which are both supported by the S-A6640 to eliminate the chance of communications failure.”
Adaptable for any platform size; Space-rated for NEO/LEO missions
Specific uses of the new S-A6640 include connectivity for GPGPU, edge computing and storage as well as network protection, resiliency and scalability in NEO/LEO space applications, especially in applications with two redundant S-A6640s installed.
The switch offers several advantages to ensure reliable communication. Fast Boot means operation is restored immediately in the event of power spike/outage. In addition, the IPv4/IPv6 dual stack routing enables the S-A6640 to be used in any type of IP network and the secure SSH & HTTPS interfaces facilitates easy remote management access.
