GPS uses satellites to provide location and time information anywhere in the world. It works by triangulating signals from 24 satellites in orbit. GPS is used for navigation in vehicles, ships, planes and more. It can display maps and provide turn-by-turn directions. A-GPS improves GPS for mobile phones by using cellular networks to assist with location. Both GPS and A-GPS are constantly improving and being used in more applications like watches, satellites, and tracking units.

1. Enhanced Navigation
Technology- GPS

2. Introduction
GPS stands for Global Positioning System, it is used for
navigation. Space based satellites are used which gives
the exact information about a particular location and
tells correct time to reach the destination.

3. How It Works
 The GPS navigation
system is a network of 24
satellites placed in Earth's
orbit by the U.S.
Department of Defense. It
provides correct location
and time information at
any position whether its a
day or night, under all
weather conditions.

4. The GPS navigation system devices find use in
several applications in the fields of
a)Military
b)Marine
c)Aviation
d)Tracking
e)Surveillance
Uses of GPS Technology

5. Number of GPS technology applications are
there
But the widely known are GPS navigation
devices which are used to receive GPS signals on
Earth.
A GPS device gives the information about the
Earth's Latitude, Longitute & Altitude.
It displays maps, including streets maps,
displayed in human readable format via text or in
a graphical format,

6. 
GPS represents turn-by-
turn navigation directions to
a human in charge of a
vehicle or via text or
speech, directions fed
directly to an automatic
vehicle.

It can suggest the
shortest route distance
between the two locations.

It also represents the
area with traffic congestion.

7. Mobile phones with GPS
capability
The GPS technology is getting updated day by
day, and its recent advanced advent is named as
A-GPS.
A-GPS stands for Assisted Global Positioning
Service.
This service enables a user to navigate through
his phone too.

8. Working Principle Of A-GPS

9. A-GPS technology was introduced for mobile
devices, it takes assistance from GPRS and
service provider network. A typical A-GPS
mobile phones uses a GPRS or other networks
for developing a connection with the server of
A-GPS.

10. GPS & A-GPS Proved Worthy
GPS technology can be used in different modules
Some of them are:-

GPS Navigation Device

GPS Watch

GPS Satellite

GPS Tracking Unit

11. GPS Watch
A GPS watch is a
device with inbuilt
GPS receiver that
work as a single unit
strap onto wrist, GPS
watches are generally
used for sports and
fitness purposes

12.  A GPS satellite is a
satellite used by the
NAVSTAR Global
Positioning System
(GPS). The GPS
satellite constellation
is operated by the 50th
Space Wing of the
United States Air
Force.
GPS Satellite

13. GPS Tracking Unit

A GPS tracking unit is used
to determine the exact
location of a vehicle, person,
or other asset to which it is
attached and to record the
position of the asset at regular
intervals. The recorded
location data can be stored
within the tracking unit, or it
may be transmitted to a
central location data base, or
internet-connected computer,

14. The GPS and A-GPS technology are being
advanced day by day, and even enhancing the
navigation experience.
Because of its different modules it can be used in
outdoors as well as in indoor applications.
