The interplanetary overlay network (ION) software at JPL is an implementation of delay/disruption tolerant networking (DTN) which has been proposed as an interplanetary protocol to support space communication. The JPL deep impact network (DINET) is a technology development experiment intended to increase the technical readiness of the JPL implemented ION suite. The DINET experiment operations center...
Delay/disruption tolerant networking (DTN) promises solutions in solving space communications challenges arising from disconnections as orbiters lose line-of-sight with landers, long propagation delays over interplanetary links, and other phenomena. DTN has been identified as the basis for the future NASA space communications network backbone, and international standardization is progressing through...
We present the telecommunications protocol processing subsystem using reconfigurable interoperable gate arrays (TRIGA), a novel approach that unifies fault tolerance and inter-planetary communication protocol offloading to implement CCSDS file delivery protocol and datalink layers. The new reconfigurable architecture offers more than one order of magnitude throughput increase while reducing footprint...
The UHF relay link through the Mars Odyssey orbiter exceeded expectations of the Mars exploration rover (MER) project and played a critical role in the return of data from the surface of Mars and in the accuracy of the rover position determination. This paper will discus the development and performance of the UHF transceivers and the Consultative Committee for Spacecraft Data Systems (CCSDS) Proximity-1...
