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.


A very interesting post about GPS technology. If possible, make a comment on this below.

The story of the computer - Full Tutorial


The calculation always made man a problem. Hence, man tried to use a convenient method, and as a result, he found a manual operating mechanism. This was called "Abacus". It was produced by the Chinese about 2000 years ago.

Abacus


This is a thin-striped wooden frame. The miniature balls are mounted on the scenes. And the lines were crossed. There is another slim collar. There are two pieces of small round balls on top of the top, each bar topping each with seven round rounds. These small balls can be moved according to the rules. They should refer to problems that need to be solved. An Abacus operator can add more speeds to the current calculator.

Russian and Japanese abacus more than Chinese Abacus. But those machines can be performed equally in the same way, and only the rules in which they work can be seen. This horizontal-mounted device is one of the number one enhancement options. Each of these wooden pieces has numbered 1-9 and added the value of each number by adding each number.

Pascaline


In 1642, the calculator discovered by French lawyer Blace Pascal named it. This is called the earliest calculator in the world. Each wheel is made up of 0 to 9 disks in each wheel of the machine, connected to a pinch and wheel. Rotating the rotors accordingly enables the number to be added to the machine.

Charles Babbage


He is a English national. He designed a "Difference Engine" machine. In 1822, its main goal was to compute multiplications and tables. At that time, however, technology had not been so advanced and technically costly planned and abandoned. After that, From 1833 to 1834, he was planning another machine, which was a machine that was steam powered. He called the "Analytical Engine".

A large number of features on the modern computer included him. Unfortunately, this machine could never be manufactured. But Charles Babbage has been able to name the name of the computer in the very top, and today he remembers him as "the father of the computer".

Ada Augusta


Also, "Ada Augusta" developed the idea of computer programs, as a friend and assistant of Charles Babbage's computer software, and as "the first computer programmer" (computer programmer ) Today is also commemorated.

Tabulating Machine


The creation of the TAB is owed by a US citizen. In 1880, Hermann Hollerith. It took about 8 years to produce these kinds of manuscripts. Herman sought to find this machine to help prevent this amount. This made it possible to do a quick calculation.

The world's first computer


His dream planned by Charles Babbage came true after 70 years of his death. Howard Aiken of the Harvard College, Hawaii, Hawaii, USA, in 1930, I.B.M. This machine was developed with a company engineer and started to manufacture this machine. This was a full automatic. This machine was capable of adding and lowering the numbers in a second. It also takes seconds for this count to count. This was the first computer to be called the Automatic Sequence Controlled Computer (ASCC).

Electronic computer


After the ASCC was discovered, its upgrading continued. During World War II, during the Second World War, a tactile gun for the Allied Forces was a prerequisite for shooting targets and was required to find the Electronic Numerical Integrator and Computer (or ENIAC) to fulfill this essential requirement.

This ENIAC computer had a faster speed than the earlier machines. It has the ability to decrypt and add 5000 reductions, 350 upgrades, or 50 split resolutions in a second. But this computer was very large.

John Von


Improvements continued. John Von Neumann has joined in developing the ENIAC. He said that the computer can not only store data and counted results.

He believed that a program could be included to do the instructions in accordance with the instructions given earlier. Six years later, in 1949, the first electronic computer was produced by the University of Cambridge at the University of Cambridge. This was the Electronic Delay Storage Automatic Calculator (EDSAC).

These developments led to the emergence of a modern computer.
