========================================
At the Unispace 3 Conference in Vienna, Austria
last year a number of serious
concerns were raised about how effectively space
was being employed to meet
the needs of developing countries. The
following article has been drafted as
part of a 100 page monograph that this being
prepared by the International
Space University (ISU) to address these concerns.
Only 4-5 pages have been
reserved for the topics that this article addresses.
It is hard to cover all
of these key topics in such a brief number of
words, but as promised here is
the initial draft for your review, comment, and
editorial (or substantive
improvement). I hope you will recall my
message over a month ago in which I
indicated that this article was being drafted
and that your participation as
joint authors was being solicited. Please
let me know if you can both agree
with the article and can help improve it.
Specific text changes (both
additions and deletions would be greatly appreciated).
Thanks in advance for
your support and assistance. Sincerely,
Joseph N. Pelton

Many of the major collective issues that humanity
must face in the first
quarter of the 21st century can profit from the
appropriate and creative use
of space technologies. Space technologies
already have proved to be crucial
to environmental monitoring and pollution control,
reversal of
desertification, protection of rain forests and
other endangered areas, vector
control, water sanitation, disaster warning and
recovery, and to agricultural
innovation and renewal. Notwithstanding
the great contributions of technology
to human wellbeing, about two billion individuals
live today with inadequate
or no healthcare, formal education, access to
clean water, or without minimal
communications infrastructure to support their
economic livelihood and social life.
The general availability of space-based communication
technologies and the
implementation of distant education and interactive
health communications
applications open enormous possibilities and
a multiplicity of innovative
solutions for dealing with the serious deficiencies
and growing demands for
education and health. It is not always
clear whether technology leads or
follows important new social applications and
market needs but,
unquestionably, satellite communications will
be a key part of the
revitalization and development of the education
and health sectors in the near future.
Telecommunications and informatics technologies
applied to the education and
health sectors are considered to be critical
elements for attaining the goal
of improving access to equitable educational
opportunities and healthcare. In
the health sector, they are important tools to
the practice of evidence-based
quality health interventions, the cost-efficient
operation and management of
health services and health programs, health promotion,
professional education,
access to knowledge databases, and the provision
of individualized healthcare.
It is expected that emerging broadband satellite
communications technology and
new stratospheric platforms will be part of the
global effort to drive the
sorely needed development of the social sector.
One can, for the first time,
foresee broadly assessable education, an affordable,
reliable, and reachable
healthcare system and global connectivity that
offer new economic hope to
those most in need.
Here are some of the important technological transformations
that provide hope
and geographic breadth regarding those goals.
New Communications Technologies
For many years there has been the hope that a
single breakthrough technology
would eventually offer everyone an immediate
and affordable access to
information and communication. It seems
now clear that integrated
technologies working together seamlessly through
globally agreed technical and
data standards, offer the greatest hope of reaching
that target. By the end
of the first decade of the 21st century we will
have deployed advanced
broadband communications able to provide multi-media
services to the desktop,
laptop computers, palmtop processors, and even
"wearable transceivers".
The development of high-power communications satellites
in low earth and
geosynchronous orbit, plus stratospheric platforms,
local loop terrestrial
wireless systems, and other advanced wireless
technologies, will make this all
possible at affordable cost even to less developed
societies. Those space and
terrestrial wireless systems will interconnect
with high capacity fiberoptic
networks to bring more information and digital
services to more people than
ever before. The key to these new systems
is the development of exceptionally
user-friendly compact portable processors and
communications devices priced in
the range of a few hundreds dollars, easily purchased
and serviced at local
electronic appliances stores. Fixed or
mobile units, including
micro-terminals, will be able to provide services
of all types (television,
radio, telephone, data, paging, and multimedia)
at an operational cost
affordable to a growing segment of the world's
population.
Although no one is forecasting an early solution
to our extant communications
and information problems via technological advances
alone, we can indeed
predict rapidly falling prices for computing,
communications, and for
satellite and wireless services. Figure
1A and B below shows how quickly
costs are falling for both fiberoptic connections
and satellite networks.
Note that fiber costs are given on the basis
of channels (or half circuits)
but satellite costs are based on duplex circuits.

2000
$ 250
Note: The figures for 1995 and 2000 take into
account advanced digital
processing (now providing 8 Kbps voice circuits)
and long term lease rates.
In general satellite costs (as driven by the
latest technology) tend to lag
some 5 years behind those of transoceanic fiber.
Satellites, by virtue of
their ability to broadcast services over wide
areas, support large-scale
networks and reach rural and remote areas.
They are a key instrument for
global economic development and service to developing
countries.
We predict, however, that in a short time "content"
development and quality
and attending maintenance costs will exceed those
of the enabling
technologies. By the end of the decade,
we expect that knowledge and content
will be the single most important limiting factor
in the deployment and
operation of education and health applications
not the technical hardware
represented by fiberoptics, satellites, and wireless
systems. The problems
associated with content development is already
being acutely experienced by
many researchers and web sites managers.
Interactive Communications and the Internet
One of the most important innovations of our times
is the explosive growth and
ubiquitous presence of the Internet. The
global cumulative aggregate growth
of Internet today is somewhere between 80% and
100% within the more developed
countries of the OECD, just over 80% in Africa,
around 100% in Asia and near
125% in South America. The Internet is
a remarkable tool for message
switching, education, healthcare, economic and
trade development, commerce,
research, emergency warning and recovery, and
general knowledge building. The
most rapidly growing use of telecommunications
satellite are related to
Internet, data, and multimedia-related services.
On the INTELSAT global
satellite system, Internet, data, and multimedia-related
services network
traffic grew from almost nothing in 1996 to over
15% of all revenues.
It is clear that any use of satellite communications,
earth imaging, space
navigation or geomatics services in the next
few years to achieve development
goals, must be able to draw on the power of Internet
when needed.
Satellite-based Internet can equally respond
to the needs of developed, newly
industrializing, and developing countries with
a high degree of flexibility.
It has now been shown that latency in satellite
transmission can be
immediately overcome by adjustment of Internet
protocols to the extent that
545 Megabits/second can be sent through 622 Megabit/second
satellite carriers
and highly asynchronous carriers between upstream
and downstream traffic can
be readily accommodated as well. In a few
years anyone will be able to access
the Internet via a number of satellite and wireless
systems via very low cost
micro-terminals.
Global and Regional Tele-Education and Tele-Health Programs
Satellite, wireless and even fiber networks already
can reach, at a reasonable
cost, rural and remote locations via global or
regional systems and extend
needed social services to underserved parts of
the world. The creation of
such networks is the easiest task in the establishment
of satellite-based
tele-education and tele-health projects but the
ability to provide low cost
fiber, satellite, and wireless services to all
countries, although a necessary
requirement, is not by itself sufficient.
The development of the educational content and
programming, the generation of
healthcare information, and the establishment
of local education and health
physical infrastructure to support these initiatives
are by far the hardest
part. National priorities and capabilities
will determine how, where, and
when applications should be deployed. Appropriateness
of project design,
development, and management are critical for
ensuring success. The process of
installing new systems is often difficult and
requires tremendous discipline.
Daily demands on personnel, changes in the market,
and conflicts about running
the educational and healthcare services are all
potential barriers to
realization.The provision of educational and
health services must respect
local legal and ethical rules, standards of practice,
and cultural and social
beliefs this is a much greater challenge
than the technological issues.
Involvement of all stakeholders is an essential
prerequisite since any project
that does not have local involvement has a very
high failure rate an example
being the INTELSAT's Project Share and Project
Access.
The installation of a new work paradigm and technology
is a tremendous
undertaking for any organization, affecting every
area of the operation.
Often, because of time and budget constraints
as well as the perception that
change is not immediately necessary, many organizations
wait until there is no
other option but to carry out changes within
short time frames and thus
increasing the risks of failure. For a
large, multisite organization the
issues are the same, but the complexity increases
tremendously. It is
important to note that the only successful long-term
tele-education and
tele-health programs via satellite that have
proved successful in rural and
remote locations of India, China, Indonesia,
and Brazil, have been those where
content and project management were locally developed
or adapted and closely
coordinated with local teachers, teaching aids,
and medical clinics.
There are a number of initiatives that provide
the best program development
models. These initiatives are widely supported
by international cooperation
agencies, educational institutions, and broadcasters.
They include the World
Bank and its InfoDev Program, the Foundation
for the Support of the United
Nations in Japan, the Global University System,
GLOSAS, the World Health
Organization, the Pan American Health Organization,
UNESCO, the International
Telecommunications Union, the National Technological
University, the Open
University, most of the development agencies
of the OECD countries, PEACESAT,
the University of the South Pacific, the University
of the West Indies, TV
Ontario, and the Sir Arthur C. Clarke Institute
for Telecommunications.
We can still be encouraged by progress achieved
during the 1990s. The Chinese
National TV University now reaches many millions
of students and teachers with
programming developed by the Central China Television
and the Chinese Ministry
of Education. This is among the world's
largest tele-education programs and
started with the INTELSAT Project Share program
in 1985-86. The INSAT system
of India, a joint effort of the Indian Space
Research Organization and the
Indian Ministry of Education, now distributes
educational programming to over
1 million students. PEACESAT continues
to operate throughout the South
Pacific and the UDIWITE network is operational
throughout the University of
the West Indies. There are also many successful
tele-education and
tele-health programs operating in the Caribbean,
Brazil, Indonesia, rural
Australia, Canada, the U.S., and dozens of other
countries.
In general, the technical and network implementation,
programming, content
development, local support operations, user equipment
and costs associated
with tele-education projects are easier than
the tele-health applications.
This is because tele-health, particularly real-time
tele-consultation,
requires higher bandwidth and reliability, specialized
and expensive
equipment, and access to highly skilled information
providers and specialists.
Even so, progress is being made in many trial
programs around the world. In
most cases healthcare applications can profitably
"piggy-back" on networks
first established for distance learning.
Recently there have been organized
efforts to institutionalize some of these efforts,
for instance, Alenia
Aerospazio has seized the initiative to create
two new joint ventures to
provide tele-education and tele-health services.
These projects include
TELBIOS which now operates the largest satellite
based tele-health operation
in Europe and Skyplex-Net, which operates one
of the largest tele-education
satellite networks in Europe. Projects
established in Canada to provide
medical services to offshore oil-drilling rigs
have now been adapted to use in
developing countries and remote regions.
The Millennium Village and Integrated Development:
Trial Projects that can be
Globally Cloned
Most development projects around the world have
a tendency to address needs in
a piecemeal fashion. The Ministry of Energy
addresses the issue of
electricity and fuels, the Ministry of Education
is concerned about improved
schooling, the Ministry of Health worries about
disease prevention and medical
care while other government units address economic
development, financing,
employment, and training. The "Millennium
Village" (MV) Project, which the
Clarke Institute for Telecommunications and Information
(CITI) is organizing
in partnership with many different groups around
the world, attempts to solve
that atomization of national efforts. The
MV Project aims at designing and
promoting of a new, integrated, and economically
self-sustaining advanced
technology development general model that can
be "cloned" in various parts of
the world. The thesis of the MV project
is that an integrated plan is more
efficient, cost less money and, hopefully, create
enough new jobs and wealth
to pay for the development investment and the
sustainability of implemented solutions.
CITI, GLOSAS and the Global University System
in partnership with the World
Bank/InfoDev and others recently launched an
initiative to create a Global
Service Trust Fund (GSTF) to establish a global
wireless and satellite
broadband Internet for GUS' regional activities
in Asia/Pacific, North,
Central, South America, Europe and Africa.
The expected result of the
initiative is to provide their tele-education
and tele-health programs with
access to low cost or free broadband networks
to rural and remote parts of the
world. The core problem of how to develop
the educational and medical support
programs, however, remains to be solved.
The initial project is planned for rural Sri Lanka,
the home of Sir Arthur C.
Clarke, and site of past projects by some of
the key participants in the
trial. The idea is to apply a combination
of developmental disciplines,
knowledge, skills, technologies, and systems
solutions integrating space and
terrestrial technologies to achieve a new development
model that is
economically and socially sustainable.
Affordable electrical power,
satellite- and wireless-based telecommunications
and computing networks,
tele-education and training programs, tele-health
applications, combined with
economic development activities, will generate
new jobs and sustainable social
and environmental improvements. As in many
technological initial deployments,
it is unlikely that the first attempt will fully
succeed, but carefully
monitoring and evaluation processes will be carried
out in the anticipation
that the second or third try, after assessment
of expected and unintended
results are conducted, will indeed prove viable.
Conclusions
Dramatic gains have been made in the application
of space communications and
interactive information networking technologies
to aid development efforts in
education, health promotion, remote medical services,
economic improvement,
and a broad range of information services via
Internet web sites. For the two
billion people who lack basic social services,
satellite networks in tandem
with terrestrial information systems offer significant
opportunities during
the coming decade. Content development
and maintenance, not technology, will
be the major problem in the deployment of educational
and medical support
programs. Information and communications
services may well be the most
important use of outer space because of their
impact in equitable access to
quality education and healthcare and their contribution
to economic
development besides the already well established
role of satellite-based
technologies in environmental monitoring, peacekeeping,
navigation, and
general communications. It is no accident
that the word satellite originated
from the Latin "satelles", meaning a follower,
attendant, or servant for
today's satellites are indeed servants of humankind.
