STANDARD SPACECRAFT INTERFACES AND IP NETWORK ARCHITECTURES: PROTOTYPING ACTIVITIES AT THE GSFC

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, NevadaAdvancements in flight semiconductor technology have opened the door for IP-based networking in spacecraft architectures. The GSFC believes the same significant cost savings gained using MILSTD- 1553/1773 as a standard low rate interface for spacecraft busses can be realized for highspeed network interfaces. To that end, GSFC is developing hardware and software to support a seamless, space mission IP network based on Ethernet and MIL-STD-1553. The Ethernet network shall connect all flight computers and communications systems using interface standards defined by the CCSDS Standard Onboard InterFace (SOIF) Panel. This paper shall discuss the prototyping effort underway at GSFC and expected results.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
