11. To find location by using latitude and Longitude
data.
24 Satellites at different orbits.
Revolve around Earth twice a day.
For 2D location , 3 GPS Satellites are used.
For 3D location, more than 3 Satellites are
used.
WHY WE USE GPS?

12.  Triangulation
 Augmentation
A GPS Signal contains three different bits of
information
 Pseudo random code
 Ephemeris data
 Almanac data
THE SIGNAL

13. Receivers require clear line-of-sight thus, they will not work indoors
or where tall objects obscure the sky.

15.  Short for Global System for Mobile communications.
 One of the leading digital cellular systems.
 GSM was first introduced in 1991 and as of the end of
1997, GSM service was available in more than 100
countries and become the standard in Europe and Asia.
 GSM uses narrowband TDMA, which allows eight
simultaneous calls on the same radio frequency.
 International roaming capability.

16.  Any GSM module is using the normal GSM network
 GSM modules can be communicated to PIC-
microcontroller using normal serial USART protocol
 Communication is being done using regular GSM
modem At Commands.

17.  Low cost, easy to use for rural areas, automated
operation, and Low Power consumption.
 High secured and reliable.
 It gives information of place using GPS.
 By sending SMS through mobile, we can stop vehicle.
 It provides more security than other system.
 From the remote place we can access the system.
 Mobile number can be changed at any time.

18.  In military application.
 In public cabs.
 In private vehicles.
 In ships and boats.
 Tracking vehicle position.
 Stolen vehicle recovery .
