Aviation
In aeronautical applications, satellite
positioning and timing services have long been
an additional means of navigation.They
provide supplementary service for many flight
phases, in leisure flying as well as commercial
air transport.
In the European Union, nearly 15,000 civil
aircraft (commercial aviation and general
aviation) are currently registered, with an
additional 30,000 small private planes in use.
In recent years, scheduled traffic has increased
by about 4% per year worldwide, doubling the
number of flights within 20 years. Higher
navigation accuracy and service integrity are
required to allow aircraft separation
reduction, allowing for the increase in traffic
capacity.
EGNOS and Galileo will assist pilots in all flight
phases, from movement on the ground to
take-off, en-route flying and landing in all
weather conditions, reaching the level of safety
that will be required to cope with the
continuous increase in the number of flights.
Galileo, with the aid of ground-based local
elements, will satisfy the needs for precision
approach as defined in the aeronautical
standards.
Air traffic controllers need position, heading,
speed and time information for the
continuous management of all aircraft. Some
areas of the world lack the appropriate
ground infrastructure, including secondary
radar and communication links. Standardized
transmission of Galileo navigation data will
lead to advanced systems and techniques for
safer air traffic monitoring.
All other aviation-related operations, such as
airport surface movement and guidance
control, require precise assistance from air
traffic controllers.Airports may have surface
radar, but sometimes pilots report taxi
movements manually and aircraft are managed
using visual aids only.This has lead to severe
accidents. Satellite navigation and particularly
Galileo will improve operations safety. [1]
