Overview of the GPS

Introduction So far, our ancestors have used different ways to find the way on the planet. They used the position of the stars, proposed landmarks, and created detailed maps so that they did not get lost. In today's era, as long as you are using a mobile device called GPS, it is easy to find exactly where you are on the planet and find it without getting lost. I know that GPS can be found in cars, boats, airplanes, computers, and other new equipment, but recently when I asked my father's friend who purchased GPS I am interested in how the system works was.

The AVL system is an advanced way to track and monitor any remote vehicle using a device that sends and receives signals via GPS satellites. AVL includes Global Positioning System (GPS) and Geographic Information System (GIS) and provides the true geographical location of the vehicle. The AVL system consists of PC based tracking and scheduling software, wireless system, car GPS receiver, and GPS satellite. GPS based systems are widely used in both GPS - based AVL and road sign - based AVL.

How does the accuracy of GPS improve? In agricultural applications, the most common way to offset GPS errors is to use differential GPS or DGPS. In the DGPS system, the GPS receiver is placed in an exactly known place (Figure 4). The base station receiver will calculate the error between its actual position and the position calculated from the GPS signal. The error message is sent to the mobile station receiver being used in the field and the calculated position information can be modified from the GPS signal. Most of the variance corrections are provided by US Coast Guard (USCG), WAAS (FAA's Extended Area System), or private wireless carrier or satellite link order.
