This article summarizes the EU's activities in the ACTS program on mob
ile satellite communication, which are directed to the satellite compo
nent of UMTS. In this article the projects INSURED, NEWTEST, SECOMS, S
INUS, and TOMAS are briefly introduced, and their R&D work on the serv
ices implemented in the different test platforms, the network integrat
ion scenario into the UMTS network, the studies performed for the air
interface, the mobile terminals implemented, and the demonstrated appl
ications are summarized. Furthermore, a new approach using neural netw
orks for adaptive channel equalization and the concept for an EHF/Ka-B
and system are introduced.
