Let's learn about GPS (Global Positioning System) technology


GPS, or Global Positioning System, is a Satellite-based Navigation System.


A Navigation System is a way of looking at where you are located by a map. This is carried out by the US Department of Defense's 24 satellite satellites. This was first used in military operations, and later, in 1980, the government allowed civilians to use it. This GPS technology is successful in any part of the world regardless of whether, but 24 hours a day. An important fact is that it is a completely free service.


How does this work?

Every GPS satellite transmits facts to the Earth, travels twice a day on its brakes. GPS receivers use this facts to calculate their place. This calculation is done by comparing the time the GPS sends to the signal from the satellite. It detects the distance between the Receiver and the GPS Satellite. Thus, one receiver receives one receiver using several GPS satellites and maps the receiver's place to the receiver.


The receiver also requires at least two GPS-s at a time to show the place at which it is in two-dimensional mode, in mech and longitudes. Using GPS Satellite 4 or more, you can view your place as 4D, such as latitude, longitude and altitude.

In this way, the receiver receives the speed, direction, path, distance traveled, the distance from the source to the voyage, the sunrise and the sunset when the receiver receives one.


How right is GPS?

Today, the used GPS Receiver is high in size, because of its parallel multi-channel design. Garmin's 12 parallel-channel receivers are able to retrieve data provided by Satellites in a short period and to keep up a strong connection as soon as they are put into action. Garmin® GPS receivers can accurately calculate their place by ascending to 15m from ash.


The WAAS - Wide Area Augmentation System - comes with Garmin GPS receivers that can cut their accuracy to 3 m. WAAS does not have any accessibility tools. It can be further defined through Differential GPS (DGPS) (see above). This DGPS system is supported by a network of fixed towers using beacon transmitters operated by the US Coast Guard. One must use this service as well as a different beacon receiver and beacon antenna.


GPS Satellite System

There are 24 satellites located 12,000 miles over the Earth. These run smoothly and less than 24 hours each satellite travels through two circles. They travel at a speed of 7,000 miles per hour and the satellite is powered by the sun. A battery backup is used to power continuously in the eclipse. Each satellite uses the little rocket boosters to keep track of them.


The following is some information about GPS Satellite.

  • The first GPS Satellite was designed in 1978.
  • The first time a GPS Satellite 24 was established in 1994.
  • Each satellite is capable of operating up to 10 years, and the satellites to be used in the meantime are being produced.
  • One satellite is weighing 2,000 pounds and consists of a 17 foot cross-section of solar panels.
  • They send a transmitter of 50w or less power.
  • These waves emit a range of UHFs of 1575.42 MHz. The FM radio we use uses a range of 88-108MHz.
  • Thus, three information sets are transmitted, such as Pseudorandom codes, Ephemeris data, and Almanac data.
  • Pseudorandom is the code to find each satellite.
  • Ephemeris data indicates that the satellite is in good condition.
  • Almanac data identifies the satellite as to where the satellite is to be at the time of the day.
