trialled a Wi-Fi access system connected to an
interactive satellite terminal for use on trains with the
capability to support broadband internet and intranet
access as well as local multimedia content such as short

market is high-speed trains in Western Europe where
journey times allow for its use. The 21Net system
addresses the needs of train passengers, especially
business passengers, and allows them to access the
internet, their email and corporate VPNs.
The objective is to demonstrate the low loss, mass and volume reduction for a high power filter at Ku Band using advanced dielectric material, considering all the high power issues.
The potential benefit of SANTTSUR to
surgeon trainees will be in providing an interactive
learning environment and high quality learning materials
at the workplace. Important to these trainees and
Surgical Tutors, all with busy schedules, is that no time
is wasted travelling to a different location. The course is delivered via satellite through 30 high quality, live,
interactive TV programmes over a period of a year to
selected hospital centres, based on a modular syllabus
that is complementary to the Royal College of Surgeons
of England's (RCSEng) established course materials.
DELTASS is a mobile telemedicine demonstrator designed to improve the efficiency of the management of rescue, first aid and emergency operations in disaster telemedicine contexts such as earthquakes or large explosions. The DELTASS system enables the mobile paramedical or medical teams to coordinate their actions towards victims, to generate and transmit localisation and medical data directly from the disaster area to a coordination centre in an automatic and easy way, using adapted light space-backed equipment. DELTASS system allows also distant medical equipment or image manipulation and real time telediagnosis by specialised medical doctors at remote sites.
The main objective of the "Web Global
Medical System" (WEBGMS) is the availability of a
common base of multimedia data relevant to any
patients in remote sites. A package delivery service has
been used to multicast informative video clips and
content from a pharmaceutical firm evaluating the
system for commercial use. Virtual community has been
represented in the pilot base by 35 hospitals in Europe
collaborating with scientific associations in the field of
Marrow Transplant and Haematology.
The project OSCAR (Optically-pumped Space Cesium Atomic Resonator) aims to develop a concept of industrial compact optically pumped cesium atomic beam standard exhibiting superior frequency stability as compared with its commercial counterparts, namely, magnetically pumped cesium clocks.
I-GARMENT is aimed at developing fullbodied
smart garments equipped with sensors to
monitor position, vital signals (temperature and heart
beat) of the agents. This information will be sent via a
wireless link to Civil Protection Officers in the HQ,
processed and returned to the field officers equipped
with PDAs and/or TabletPCs. The project will develop a
service for the Portuguese Civil Protection to accurately
and effectively manage the human resources on the
field in near real-time, guaranteeing the service will
work even when terrestrial communications are
unavailable.
In the proposed experiment, radiation effects that are important for instrument and spacecraft design are studied by employing several technology experiments in conjunction with radiation monitoring instruments.
The project objective is to fly a Mechanically Pumped Fluid Loop loop Flight Experiment (MPFL-FX) as Technology Demonstrator Program (TDP) on the Alphasat mission.
The objective of the Alphasat TDP#1 - Broadband Data Relay project is to verify the performance of a 2 Gbps optical LEO-to-GEO link in-orbit as part of an experimental broad-band data relay transmitting a 300 Mbps user data stream from Tandem-X to ground.
The objectives of this project are to demonstrate the feasibility and reliability of using low-cost detectors to sense the atomic oxygen airglow of the atmosphere from space, and estimate the performance of a low-cost earth sensor that uses this concept.
This activity developed the ?Atmospheric Propagation and Profiling System? (ATPROP) advanced ground-based microwave radiometer, for radiowave propagation assessment at Ku, Ka, Q/V and W bands.
SKY EYE SPY (SKISPI) is a system that
adds an additional level of security to data transmitted
over a satellite communications link. This project aims
to produce a prototype system capable of either
permitting or refusing access to digital data dependent
on the location of the person, or system, that is making
the request for access. The system will combine
methods of encryption with the latest high sensitivity
GPS receivers and will be directly applicable to a variety
of satellite communication services, ranging from TV
broadcasts to business (point to point) transmissions.
The project objective is to develop optimal guidance laws for full electric propulsion station-keeping of GEO satellites with their corresponding thrusters accommodation architectures.
This study was motivated by the need to investigate new techniques for the capacity improvement of multimedia broadband satellite systems. In particular, the use of satellite systems with large numbers of beams and operations at a higher frequency limits the system performance interference. Hence, techniques which go beyond ACM in mitigating interference and improving system throughput were the objectives of this work.
Within this project, GPS measurements at high sampling rates (50 Hz) have been recorded in both high and low latitude regions. A data base has been constituted. These data have been used to derive the scintillation characteristics and improve scintillation models.
The Healthtrack Professional Service in
Home (HPS in Home) aims to provide professional
healthcare services to general practitioners directly to
their home. This is achieved by utilising the Sky Digital
TV platform to deliver the service as an interactive
television (iTV) application. The HPS in Home service is
planned ultimately to meet many of the continuing
medical education needs of healthcare professionals.

Sat-n-Surf aims to take the results of
Sat@Once, a previous ARTES 3 project, and enhance it
with additional tools and means to become a full-sized
new broadcasting medium, on a par with popular radio
or television. Through the Casablanca technology, Sat-n-
Surf exploits the broadcasting capability of the satellite
to transmit the same information to all listeners. This
approach is the opposite to the familiar point-to-point
approach (unicast) of the Internet, where data goes
from one source to only one destination. Sat-n-Surf acts
as a "virtual matchmaker". On the local PC of the user
the application, a "Magic Mirror" runs that matches
together the personal interests of any given user and
profiles of the content that is sent by satellite. The
Magic Mirror "catches" all the information of the day that
may be of interest to his master.
