Question

What is GPS? Mention its uses.

Answer 1

Hint: The GPS which stands for Global Positioning System has been developed in order to allow the determination of geographical locations by the military and civil users. The GPS is based on the use of satellites in Earth orbit that transmits information which allows measuring the distance between the satellites and the user.

Complete answer:
The different uses of GPS include:
1. Locating Positions: Locating position is the main and most common application of GPS tracking. For instance, if one is hiking with his/her friend and gets separated, the GPS can help in finding one’s location in a short span of time.
2. Preventing car theft: GPS works as an excellent anti-theft device. By installing a tracking device on vehicles, it allows us to locate and trace the accused in case our car gets stolen.
3. Mapping and surveying: GPS can be used while mapping and surveying projects. The projects include mapping of highways, power lines, crops, soil types, rivers. Using GPS while surveying also saves companies time and cost.
4. Tracking for law enforcement: The police and the investigators also use GPS as it allows them in tracking and catching criminals. The authorities will just have to glossily attach a tiny GPS tracking on the suspect’s vehicle so as to track the suspect and the prime location.
Keeping track of elderly people: One of the widely known uses of GPS is keeping tabs on the elderly. This helps us take care of a senior family member who has a tendency to wander alone and have difficulty finding a way back home.

Note: The GPS has no doubt been playing an important role in our lives through its useful way of tracking. It may be safely predicted that most citizens will come to depend on it in one way or another in due course of time.
