Road applications
The road sector is a major potential market
for GNSS applications. Satellite navigation
receivers are now commonly installed in cars
as a key tool for providing new services to
people on the move such as: road user
charging, real time traffic information,
emergency calls, route guidance, fleet
management and advance driving assistance
systems.
As road user charging systems are being
considered for highways, roads or urban areas,
either to pay back capital investment,
contribute to maintenance or to help control
road congestion, it will be important to ensure
that adequate accuracy, availability and
continuity is provided. One hour of loss of
signal disruption a year, which corresponds to
an availability of 0.9998,would lead to a loss
of approximately € 400,000 for the Toll
Collect system in Germany. Galileo will bring
the necessary performance levels for these
applications.
In the USA, by combining satellite navigation
tracking and wireless communications, the
new telematic systems will offer automatic
post-collision notification integrated into the
current E-911 emergency networks. In the
event of collision, onboard systems
immediately transmit alerts along with details
such as location, magnitude and number of
passengers involved to emergency response
centres operated by Cross Country
Automotive Services.
It is estimated that the real growth of GNSS
use in this market will occur over the next 5-
10 years, with Europe and N.America taking
the lead in this respect. In 2020, there will be
over 330 million cars with GNSS-based
navigation systems onboard.
By 2010 there will be more than 660 million
cars, 29 million buses and trucks and 214
million light commercial vehicles worldwide.
It is expected that in-car navigation systems
will be “dual mode”, i.e. based on Galileo and
GPS.The average price will tend to stabilise
around a minimum value as in the computer
industry, in this case around € 500 (with a
constant increase in the functionality and
improvements in man-machine interfaces, etc.)
With these assumptions, the total annual gross
turnover of this market will reach 25 billion
Euro in 2016.
This trend is based upon the replacement
cycle of new cars, with the after-sales market
size remaining marginal, unless the current
trend for portable, PDA-based navigation
devices catches on.
From 2015, it is likely that Galileo signals aided
by a network of continuous monitoring
stations will provide vehicle accuracies of well
under 1 meter and could be used in
conjunction with other sensors in Advanced
Driver Assistance Systems (ADAS), for
example, to help vehicles navigate along the
highway lanes automatically. [1]
