Satellite Systems Engineering and Economics
challenge for a new entrant is to develop a new niche, gain the spectrum and
orbit resources, provide for market entry, and create and manage the instant
infrastructure for maximum advantage.
The companies that will be successful are those that:
•
Properly play the space game. They obtain the right orbit slots (GEO) or
orbit resources (non-GEO) and frequency assignments. From there, the satel-
lites must have high capability and utilize proven technology to reduce risk.
•
Lead the ground game. They get the right partnerships with equipment
suppliers, service providers, and distributors. To that is added the key aspect
of market access and local licensing.
Success is not a given—the project must have adequate funding to implement
the system and deliver services during the initial lean years. Furthermore, having
satellites in orbit is not enough. The ground partnerships need money, too. Making
all that happen in a coordinated way makes the industry unique.

Satellites Versus Fiber Optics
The versatility of satellites should allow them to fill important and vital needs even
as fiber optic networks extend to the home. Likewise, mobile and fixed wireless
systems cover much of the developed land areas, potentially reducing the need for
satellites. At the same time that satellite applications are evolving in response
to competition from terrestrial systems, the technology base also is undergoing
evolutionary change. There is every reason to expect that the capability and versatil-
ity of satellites and Earth stations will continue to improve significantly over the
coming years. That provides a technology push all over again, allowing system
designers and operators to approach new applications and markets with powerful
hardware and software capabilities. Lower costs from microminiaturization in user
equipment and advanced satellite payloads have produced a low-cost satellite radio
service, and new two-way interactive schemes are on the horizon. Other advances
help maintain this medium as important and cost effective for decades to come.
Not least of those is HDTV, which the terrestrial networks strain to address but
which becomes a normal facet of modern digital DTH systems.
This picture provided an introduction to the following discussion of the lineup
of valuable services that satellites will provide in decades ahead. We see that the
near term is dominated by the technologies, systems, and applications that were
under development just prior to 2000. At the same time that satellites are addressing
new markets and services, the terrestrial networks are evolving and improving.
Keep in mind that applications often appear out of nowhere and some of the more
important ones to come have not even been thought of yet.
