GPS Tracking Mysteries: What is the bandwidth of the GPS?
Global Positioning System (GPS) is a precise navigation and positioning tool. Developed by the Department of Defense in 1973, GPS was originally designed for soldiers and military vehicles, aircraft and ships to help accurately determine the various parts of the world.
Today, the use of GPS to extend both the commercial and the academic world to take. Commercially, GPS for navigation and positioning tool for airplanes, boats, cars, and almost all outdoor recreational activities such as hiking, fishing and canoeing. In the scientific community, GPS plays an important role in the earth sciences.
Meteorologists use weather forecasting and climate studies, and geologists can use it in a very precise method of measurement and earthquake studies to measure tectonic movements during and between earthquakes
GPS frequencies.
GPS device requires a number of different “channels” or frequencies, some of the development and uses some of the “ordinary” GPS units.
The principle of frequency of the GPS system is 1575.42 MHz. It is 1.57542 GHz or 1.57542 billion cycles per second.GPS bandwidth
Bandwidth is the difference between the upper and lower frequencies in the continuous spectrum. It is usually measured in hertz, and may sometimes refer to sometimes move the band bandwidth baseband bandwidth, depending on the carrier frequencies context.GPS L-band 1227.6 MHz, 1575.42 MHz, a bandwidth of less minus the top, so it comes out of the 347.82 MHz,
GPS blockers
GPS works by sending a bad signal to the private signal at the same frequency as the GPS device, a noisy signal, which will receive or send any useful information. There are several types of noise signals can be sent to a few questions about the narrowband Gaussian signal, for others a simple continuous wave. There are several devices on the market locally block GPS. These are portable, hand-held devices capable of jamming GPS signals, leaving the receiver void of GPS signals.
If you plan to buy a jammer, make selection of the frequency blocks in the sense that the jammer is local and not interfere with ambulances and other communications outside the company.
