Delay/Disruption Tolerant Networking (DTN) " bundles " have been proposed for deep-space communication in the " Interplanetary Internet. " This paper describes the first DTN bundle protocol testing from space, using the United Kingdom Disaster Monitoring Constellation (UK-DMC) satellite in Low Earth Orbit (LEO). The mismatch problems between the different(More)
This document describes the requirements and desired properties of Network Mobility (NEMO) Route Optimization techniques for use in global-networked communications systems for aeronautics and space exploration. Substantial input to these requirements was given by aeronautical communications experts outside the IETF, including members of the International(More)
A Delay-Tolerant Network (DTN) is a necessity for communication nodes that may need to wait for long periods to form networks. The IETF Delay Tolerant Network Research Group is developing protocols to enable such networks for a broad variety of Earth and interplanetary applications. The Arctic would benefit from a predictive velocity-enabled version of DTN(More)
A tunable diode laser has been incorporated as a source in an operating high resolution vacuum grating spectrometer. The advantages of such a system for recording molecular spectra have been elaborated. In the process of developing this system, several practical problems came about, and it has been considered useful to document the manner in which they have(More)
