GNSS & GPS Modules

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
