Imagine a world where you can always find out where your children are, wherever they are. Nowadays, this is possible thanks to GPS technology. This system, which was originally developed for the needs of the US military, is now used in everyday life and has become a key part of smart watches for children. But how exactly does GPS work and how does it help keep your kids safe?
What is GPS ?
GPS, or the Global Positioning System, is a network of approximately 30 satellites orbiting the Earth. These satellites emit signals that any GPS receiver, such as your child's smart watch, can receive to determine their exact location.
How does GPS determine location?
GPS works on the principle of so-called "triangulation". Your child's smart watch receives a signal from several GPS satellites at the same time. Each satellite transmits information about where it is and what the exact time is. The watch's receiver picks up this signal and uses it to calculate your child's exact location using the time it took for the signal to travel from the satellite to the watch.
Types of GPS signals
There are different types of GPS signals:
- C/A Code (Coarse/Acquisition) : This signal is publicly available and used in common GPS receivers like your child's watch.
- P Code (Precision) : This signal is intended for military purposes and is more precise.
- In the future, C Code for civilian use and M Code for military purposes will be introduced, which will allow even more accurate and reliable localization.
Why is GPS important for your children?
Smart watches with GPS for children give parents peace of mind. Thanks to GPS location, you can find out where your child is at any time. It is perfect for situations when your children are playing outside, going to school or on trips. With this system, you are sure that your child is always just a few clicks away.
