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)
The popular Internet Protocol (IPv4) has been used operationally in space on the Disaster Monitoring Constellation (DMC) satellites for remote sensing tasks since 2003. The UK-DMC satellite carries the Cisco router in Low Earth Orbit (CLEO) as an experimental payload, and use of IPv4 with CLEO and to command and control the UK-DMC satellite was demonstrated(More)
CLEO, the Cisco router in low Earth orbit, is a secondary experimental payload onboard the UK-DMC disaster-monitoring consortium remote-sensing small satellite built by Surrey Satellite Technology Ltd (SSTL). That router in space, its mobile networking capabilities, and the satellite's imaging capabilities have been proven as part of a demonstration and(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)
