User terminals for Communications-On-The-Move (COTM) systems and Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) satellite ground terminals require antennas with high gain and steerable beams. LEO cubesats offer unprecedented opportunities for scientific discoveries as well as commercial space adventures. Internet is provided to aeroplanes, ships and defence and other vehicles by COTM system...

The current prototype of the Genoa Active Message MAchine (GAMMA) is a low-overhead, Active Messages-based inter-process communication layer implemented mainly at kernel level in the Linux Operating System. It runs on a pool of low-cost Pentium-based Personal Computers (PCs) networked by a low-cost 100base-TX Ethernet hub to form a low-cost message-passing parallel platform. In this paper we de...
