Our World without Global Positioning System?

A year ago, when the satellite navigation at Ben Gurion Airport in Israel left working with the assistance of satellites, the aviation authority abilities were there to protect the planes from mishaps.

The closure of the satellites was most likely a mishap, presumably because of a deliberate exertion by Russia during the battle in Syria to forestall radio or radar signals from meddling with some other sign.

Notwithstanding, this episode featured a significant issue and that will be that the Global Positioning System or GPS could be meddling. Todd Humphreys, a Communication engr: at the University of Texas at Austin in the US, says there is a developing need to make GPS more secure, more grounded and better.

Daily Life Uses of GPS:

In today's life GPS has become the focus of our daily activities. The simplest way to do this is to find out which part of the planet the GPS wave receiver is in at a time. It is present in our mobile phones, in our cars.

It helps ships navigate safely through difficult sea lanes by informing them of the directions in navigation, which acts as a modern lighthouse.

One of the few things that is not very well known is that ports may not be able to function without them now because their installed cranes now operate with the help of GPS and they are key in the delivery of goods. The role of car makers and supermarkets in moving their destinations very fast.

Without GPS, our supermarkets will be empty and prices will go up.

The construction industry uses GPS to survey the ground when work begins somewhere. Fishermen seek guidance from them to stay within the legal limits in their areas.

But GPC is not only the source of your housing but it also provides information about time.

This cluster of about 30 satellites around the planet currently uses atomic clocks to tell the exact same time so that signals can be sent at the same time. Users can also use it to determine the tenths of a second.

Mobile phone networks use GPS to accurately determine the time according to their original ground station, while the financial and banking systems also rely on it for accurate commercial payments and receipts.

The Global Positioning System is currently playing an important role in the study of animal behavior:

I would be completely inactive without this satellite system. But is there a system that can replace it? And will we be able to function without this existing system? A five-day shutdown of a satellite navigation system would cost 6.5 billion, according to a report prepared for the British government by the London School of Economics. Shutting down the navigation system for just one day would cost the U.S economy 1 billion a day, and if it happened during the April and May sowing days, it would cost 1.5 billion a day.

GPS Jamming:

GPS shutdowns happen quite frequently. Military authorities in different areas often intercept and block GPS signals during testing of a new device or during military exercises, which is called 'jamming'.

The US government itself often conducts tests or exercises during which these satellites are 'jammed'. In any case, once in a while the satellite quits working because of specialized issues.

There is no doubt that there are other satellite systems in the world right now. Russia's Glonas, Europe's Galileo and China's Bydownez all work in the same way with GPS. But growing technical glitches or 'jamming' from satellites to housing assessment devices interfere with signals and make them ineffective.

"Most military organizations are now against jamming," says Charlie Curry, a fellow at the Royal Institute of Navigation and co-founder of Coronos Technology, a field company.

Military agencies are concerned about their own. The satellite navigation system was originally designed for the US Department of Defense, but now it guides everything, from drones flying to naval ships, from a smart bomb to an evil soldier. And now it's all in jeopardy.

Criminals also use GPS jamming technology, which is readily available online.

They use this jamming to keep stolen cars out of police custody and don't care how many people are affected by their actions. And then there are the bigger dangers.

Natural disasters can cause similar conditions. A major solar storm, such as the Carrington event of 1859, could bring down entire satellite systems, much like a military strike.

Suppose GPC and other related technologies suddenly disappear - what alternatives do we have to make the world run smoothly?

A possible alternative to GPS could be the modern version of Long Range Navigation (LoRNE), which was used by ships to cross the Atlantic during World War II
While old-fashioned maps may help us find places, many aspects of our modern lives will stop working without GPS. Initially, Lorraine technology worked only a few miles away, but in the 1970s it would be able to mark a location within a few hundred meters. The UK and other countries stopped using Lorraine transmitters after the introduction of GPS in 2000.

However, now the latest and better-performing Loren technology, called e-Loren, can be just as accurate as GPS. This new e-Loren uses state-of-the-art signaling devices with the 'Differential Correction' technique, in which the signals are reviewed and refined according to the station so that it can be used perfectly. Be right.

The modern and improved version of the Lorraine is said to be able to determine the exact location from a distance of 10 meters. Unlike GPS, it can also transmit signals inside buildings and basements, mainly because it uses a lower frequency and more power to send signals. E-Loren's powerful signals are hard to block.

No new infrastructure will be required for other methods. Long before the invention of the radio, ships determined their directions with the help of the sun and stars using an angiometer. The method of determining directions with the help of stars and planets in the sky continued in modern times.

And surprisingly, tridents such as ballistic missiles still determine their direction in flight from space objects in space. With the help of stars, you can determine a place on the earth around a circle of a few thousand meters.

Latest:

But recently an American company, Draper Laboratory, has developed a new and innovative type of global positioning in space called the 'Skymark', which can be used with a very small telescope, automatically, the International Space Station and the Earth and stars. Objects orbiting planets from objects orbiting other orbits around the planet.

By making skymarks from countless fast-moving objects in the sky, they can point in a much more accurate direction than the slow-moving stars of old.

Skymarks use data from visible dead and living planets and pinpoint a location within a 15-meter radius, which is as accurate as GPS.

Benjamin Lane, Draper's engineer and group leader, says that sometimes it can be even more accurate, but it depends on how many planets it can see at once. There is only one problem and that is which planet is the basis of the reference.

Another downside is that this technology only works in the case of clear skies. Infrared light is used instead of visible light which passes easily through the clouds, however, in the North and South Poles where deep black alternation is more prevalent, it has no special advantage.

Inner navigation may be used for static orientation in everyday work, which uses a set of accelerometers to determine the speed and direction of a vehicle after determining its position. Its original models are currently in high demand, and helps vehicles inside tunnels.

 

The problem with inertial navigation is that it doesn't stay in one place, it keeps changing its arbitrary position and it doesn't stay right and errors start happening, so the inertial navigation that is attached to your car After the PS is off for a while, it stays on for a while.

The error of not being able to stay in one place can be overcome to a great extent by installing quantum sensors. In the world of quantum, atoms and particles behave like matter and waves, and acceleration changes this behavior of their properties.

A French company, IX Blue, is developing a GPS-level machine using this technique, while a team from Imperial College London is working with laser specialist M Squared and He developed a model of the portable quantum accelerator in 2018.

Such quantum sensors are still limited to laboratories and will take a long time to become a commercially viable product.

Optical navigation may soon be on the market, using ground signs such as buildings, intersections, etc. for navigation through the camera. A model of this, 'Digital Scene Matching' was developed for cruise missiles some time ago.

'Image New', developed by American scientists for the US Air Force, is a state-of-the-art optical navigation system for aircraft. It contains a complete database of land in a region that compares to camera videos and determines the actual location. The 'Image New' has been successfully tested on many aircraft, but it can also be used on cars.

For the first time, a Swedish company, Everdron, has been able to deliver supplies to hospitals via drones without doctors. Their system of optical data ... What the camera sees determines its speed ... And searches the destination like a GPS by comparing images seen on Earth with its own data.

Of course, this method requires pre-existing data for accurate images of the area in which the destination is to be located, which requires constant data improvement and powerful memory.

The UK is developing an alternative to time synchronization that will provide data in the form of the GPS National Timing Center program, which will be the world's first service. When it becomes operational in 2025, it will be associated with atomic clocks installed in various parts of the UK and will send signals via cable.

This means that if the satellite signals become inactive, and in such a case when the center becomes insecure, then whether it is due to an attack, due to a technical glitch, due to a cyber attack or just an accident Due to this, it can be used as an alternative.

This means that satellite navigation systems like GPS will not be replaced by a single system and we may use a variety of systems in combination, there is a different ratio for ships, something else for aircraft and cars. Be something else

The US Department of Communications is currently researching a suitable alternative to GPS. The real question is whether an alternative will be ready soon in the near future.

We are now becoming accustomed to much more accurate navigation. Automated cars, cargo drones, flying taxis will all be visible to you for a decade. And they will all rely on GPS.

Curry believes that a person, sitting in a suitable place, can disable the GPS of a big city like London through a powerful jammer. Until an effective alternative system is developed, the entire city may be completely shut down at any one time with just one click.
