GPS stands for Global Positioning System and it uses a constellation of between 24 and 32 earth orbit satellites that transmit precise radio signals, which allow GPS receivers to determine their current location, the time, and their velocity.

What is a GPS module?

The GPS module is a mountable receiver chip that can be attached to certain devices to give it GPS tracking and functions

GPS has several advantages and disadvantages, but what are they?

Advantages

The system is self-calibrating all you need to do is just turn on and use
Can be used in the field – doesn't require a laboratory or artificial environment
The technology is relatively small (typical GPS system is now no larger than a small mobile phone)
Works anywhere on Earth
Can give directions
Constantly evolving systems for greater accuracy and usability

Disadvantages:

Most systems will last only 8-12 hours before needing a battery recharge
A signal can be affected by large buildings

How do GNSS & GPS Modules work?

Through the use of the global positioning system, you are able to track your device via satellite which helps determine location, time and velocity on Earth
