GPS & SNS 

GPS

A GPS navigation device is any device that receives Global Positioning System(GPS) signals for the purpose of determining the device's current location on Earth. GPS devices provide latitude and longitude information, and some may also calculate altitude, although this is not considered sufficiently accurate or continuously available enough to rely on exclusively to pilot aircraft. GPS devices are used in military, aviation, marine and consumer product applications.

GPS devices may also have additional capabilities such as:

• Contains all types of maps.
• Provides direction for people in vehicle.
• providing directions directly to an autonomous vehicle such as a robotic probe
• Provides information about the statues of traffic. 
• Providing information about nearby shops, restaurants, fuel stations  ...etc.

                                                                                                                                 

SNS

SNS are commonly found in new cars, while GPS is found anywhere: phone, internet, computer, portable devices and many more. 

Because GPS is portable, it allows to go anywhere in the World and not worry about being lost. Another advantage is not having to worry about following the wrong road as well as finding roads which have less traffic/construction.
