GPS Navigations – the New Generation Multitasking Satellite System

In this modern age for the blessing of science and technology almost nothing is difficult and impossible. When it comes to travelling to a completely unknown place, the statement also seems to be true. People normally carriy maps while visiting to a place which is completely unknown to him. But sometimes it is really tough to them to identify his own position and the right way of his destination. But in this 21st century this is not a subject to worry about, as there is a electronic gadget named Global Positioning System navigator. These devices use GPS navigation system for working.

Originally developed by the United States, this GPS navigation system is a fully functional Global Navigational Satellite System. This system works by using a constellation of 24 Medium Earth Orbit satellite. By using a GPS navigation enabled device, one can easily determine his current location, multiple directions and time. Apart from being a company of travellers, it helps for land surveying, map-making, several commercial and scientific uses and for hobbies such as geocaching. The system also helps in many applications including scientific study of earthquakes and synchronisation of telecommunications networks.

This Sat Nav GPS Navigation system is powered by using solar panels and some small rocket boosters. Generally, there are three types of GPS devices are available in the market for general use, these are GPS Tracking devices, GPS Navigation Systems and GPS Location devices.


The GPS Tracking devices are designed to be used to identify and record where a particular vehicle has travelled to. The most popular GPS tracking devices starts to record the vehicles movements when its starts to move. Their hard drive has a longer recording life.


There are some GPS devices are available which are being uses to locate the vehicles or users of the device. These GPS devices consist of very less capacity to be used as a tracking or navigation tool. These kind of devices are often used in situation where a person or asset has been lost and to successfully recover the item the exact location is required.


For the calculation of position by a GPS receiver requires the current positions and time of the satellite and the measured delay of the received signal. The basic factor of accuracy is depends on the satellite position and signal delay.
