Geostationary
communications satellites first came into service
in mid 1960s to provide direct telecommunications
links across the Atlantic. These satellites offer
a range of telecommunications services similar to
those provided by ground-based systems, which use
cable and microwave. The advantage of satellite
is that it is able to reach every point within a
large coverage area, unrestrained by borders, oceans,
continents or rough terrain. Using satellite, broadcast
and telecommunications services are extended not
only to the people in cities but also those living
in small isolated islands and sparsely populated
rural areas. Moreover, terrestrial infrastructure
is vulnerable to natural disasters while satellite
links can serve as excellent backup in such situations.
Landlines usually take years to plan and install,
with rough terrain and inaccessible areas compounding
the problems, and sometimes rendering them economically
infeasible. In comparison, ground equipment for
satellite communications can be installed within
a few months, offering fixed costs for any distance
within the satellite footprint.
Satellite also distributes content faster than conventional
on-line delivery. It offers last mile access, allowing
content to be transmitted directly to users bypassing
the congested terrestrial bottlenecks and multiple
hops.
AsiaSat operates satellite systems that provide
telecommunications and broadcast facilities to customers
who need rapid, direct, efficient and cost-effective
communications. High-quality services are provided
by a team of experts from around the world. Each
of these professionals brings to AsiaSat extensive
experience in satellite payload, frequency co-ordination,
network planning, satellite control and customer
service. With AsiaSat's full compliance to the International
Telecommunication Union (ITU) regulations, customers
can be assured of high reliability and integrity
of service on the AsiaSat satellites.
