What is the GPS antenna?

GPS Antenna is a device that helps to strengthen the reception signal for the GPS unit, whether it is a separate unit or a built -in unit. The GPS antenna is often used in a situation where the GPS unit itself is somehow removed from the sky supervision line, as in the car to help the GPS "see" the sky without having to move. GPS antennas can be purchased for a number of budgets or cheaper home versions can be made with relatively common components. It uses more than two dozen satellites orbiting orbiting to tell the receivers on the ground or in the sky exactly where they are, by receiving their heads from multiple satellites. Using this location, the device can detect not only latitude and length, but also altitude and even heading and speed. For years, GPS has been reserved for military use in the United States, but after the Directive Reagan in 1983 opened for civilian use.

Civil GPs contain certain limitations that the US government imposes to ensure that hostile forces do not use this technology in missiles. As a result, consumer GPS is unable to work when moving at more than 515 m/s for more than 60,000 feet (18 km). During the 1980s and early 1990s, GPS was used primarily in commercial roads, such as fishing ships, aircraft or for geographical exploration. At the end of the 1990s, she began to gain popularity for hiking or management consumers and was equipped with new millenniums with built -in GPS to provide driving instructions, and mobile phones began to include GPS for instructions and location.

GPS unit has a built -in antenna, which is usually relatively small and located inside the unit. Although it is likely to work in ideal circumstances, for example, when the entry moving at slow speed or stay at rest, it may not work as it would be for,that they would be more likely to try. The GPS unit likes a clear, undisturbed view of the sky to best receive microwave signals that allow it to communicate with satellites. In GPS units inside cars, this can be problematic, so that an external GPS antenna will often be used, mounted on the outside of the car with a magnet and connected to the unit itself.

In situations such as a heavy canopy cover in tourism, a small GPS antenna built into a consumer unit may not be able to ideally communicate with satellites. In this case, the larger, more advanced GPS antenna helps unity overcome environmental challenges and provide a clear signal. Similarly, moving high speeds can overcome smaller, less sophisticated antenna and external devices can strengthen the signal.

There are a number of different types of GPS antennas, with patch and quad helixstyly are the most popular. Both have roughly the same efficacy, although many people find a quad bike to have a little more sensitivity. LimitOther types of antennas include micropers, of which the patch is one configuration, flat rings and spiral helixes.
