3 first with A-GPS navigation
3 leads the way with launch of world's first navigation
system using A-GPS
14 January 2004
3 has added a unique feature to the list of services
available to customers in several markets. The 3GEO mobile navigational
system turns a customer's handset into a perfect travel companion
by allowing quick and exact location searches. Maps available
on the screen allow customers to find what ever they are searching
for.
This world first, using A-GPS or Assisted Global
Positioning System technology, is now available in Austria, Denmark,
UK and Sweden, and will become a key feature of 3 services in
other worldwide 3 markets later.
With the touch of a button, 3GEO finds out where
customers are and leads them along the quickest path to their
destination. 3Mobile allows people to not only look at the detailed
local maps, but also pinpoint the nearest restaurant, bank, office-anything
they are looking for. 3 also offers other useful functions. For
example, with 3GEO, customers can speed up the arrival of a roadside
towing service from the OAMTC, access up-to-the-minute information
on traffic conditions, accidents, road construction and parking.
Destination points on the 3Mobile with A-GPS
3 customers are able to determine their position
automatically through two different methods. Firstly through "approximate
positioning", which offers precise results of up to about
15-30 meters and this also operates inside buildings.
Secondly and more accurate is the "Exact Positioning"
method --enabled by A-GPS. This precise location is derived through
a number of steps that are hidden from the customer. The first
step is the handset receives an approximate position, derived
from approximate network position combined with NASA assistance
data. Then the final accurate position is derived from data received
from a number of satellites. This exact position is then delivered
over the 3G network in real-time, to allow the delivery of position
sensitive customer information back to the customers handset.
