Flightradar24 (Flightradar): tracking of aircraft in real time
Not everyone knows what Flightradar24 is. But at the same time, many people have already appreciated the convenience and informativeness of this service. So, let's take a closer look at this unusual Internet service and find out how it functions.
What is Flytradar24? This is a faithful assistant to all travelers, their relatives and friends. If you have seen your family or friends at the airport at least once, you are probably familiar with the feeling of anxiety for them while the plane is in the air. In order to accurately know the location of planes in real time, the Flyradar service was created, which tracks every civilian aircraft almost all over the world and transmits the data to a desktop site and a special application.Flytradar - history and description
You will be surprised, but Flightradar is not a state initiative at all. The idea of creating such an application was ignited by ordinary people who wanted to know exactly the routes of air transport, for example, in order to know about the actual delays of their flight. The service is based on a very simple principle: in the modern world, most air carriers install special ADS-B transmitters on their vehicles. They transmit signals at a certain frequency during flight, and these signals can be intercepted and decoded with the help of the simplest equipment - an RTL-SDR receiver. Connected to a computer, it allows you to convert aircraft signals and transfer them to a map to get exact coordinates in real-time mode.
Over time, the number of volunteers who joined the service in all countries became so large that it made it possible to obtain objective and timely data about most of the planet's airspace and about those planes that fly in it. The Flytradar network currently covers most of Europe, North America, and South America, and operates in the countries of Southeast Asia, Oceania, and Australia. The Middle East, South Africa and the Atlantic islands are not forgotten.
How does Flyradar work?
We described the initial working principle of this web service above, but over time, its device became much more complicated.
In general, Flytradar24 receives signals from planes online, converts them into graphic format - and provides users with complete information about air traffic in the world.
For this, data taken from three surveillance systems are used: ADS-B, FAA and MLAT. Due to three sources, information is recorded even from those boards that are not equipped with transponders.
- Coordinate fixation system using Automatic Dependent Surveillance Broadcast. ADS-B transponders today account for more than half of the world's aircraft fleet, and this number is constantly growing, as this technology is now considered the main control system. During the flight, each aircraft equipped with such a transmitter positions its coordinates in the air with the help of GPS satellite geolocation technology, after which it transmits them continuously via a transponder. On the ground, Flytradar24 employees and volunteers track them with the help of receivers, transcribe and transfer them to a map on the website or to a mobile application. Currently, the Flightradar project's receiver fleet includes more than 9,000 receivers located around the world. Each of the receivers receives a signal at a frequency of 1090 Hz with a coverage of up to 400 km. The coverage may vary depending on the natural curvature of the planet. In general, with the help of receivers, coverage is provided over all of Europe, America, Canada, the countries of the Caribbean basin, the Japanese islands, mainland Southeast Asia, Australia and New Zealand. The exception is the space above the oceans, where the signal reception range is simply not enough. But here two other tracking systems used in the project come to the rescue.
- MLAT technology allows receiving signals from old-style transponders (Mode A/C). It uses self-developed FR24 receivers. To obtain objective data, the signal from the aircraft must be received by four such devices at once (multilateration principle). This becomes possible during a flight at an altitude of more than 10,000 feet. The higher the aircraft is, the more likely it is to track the plane. With the help of MLAT, today the territory over part of European countries and the space over North America is processed.As the company's receiving devices are produced, the MLAT network will be expanded.
- FAA is the third of the involved systems for tracking flying objects. This information comes from the American Federal Aviation Administration. That is, this is information from official radars located on the territory of America. It is especially important because it allows you to get the coordinates of those civilian flights that are not equipped with ADS-B transmitters. In addition, the long-range radar makes it possible to build routes over oceans, where ordinary receivers cannot receive signals from transponders due to their remote location. The FAA has only one drawback: it is not real-time data. According to the system regulations, data is transmitted with a delay of 5 minutes. In addition, the FAA operates only in the airspace of the North American continent and over the Atlantic and Pacific oceans in the northern hemisphere.
In addition, Flight Radar24 constantly receives information from spotters (people interested in photography and observing aircraft), so often the route on the map can be accompanied by photographs.
Where can I track my flight via Flightradar?
For the convenience of users, the service works in two versions:
- A website where you can find aircraft flights in real time.
- Mobile application with convenient functionality for working with a smartphone.
If you visit the service website, you are offered a half-hour trial session - that is, you can use FlightRadar for free for the first half hour. Then you can subscribe to work on a regular basis for a fixed fee. If you don't want to subscribe, simply reload the page to start a new session (again, free of charge).
What planes can be tracked by Flyradar
Today, with the help of FR24, it is possible to track the majority of aircraft making private, charter and civil flights. First of all, these are all models of transport that are equipped with ADS-B: Airbus, Antonov, Boeings of all models, ATR, Suchoi SuperJet, Il and Tu of new models.
Among those types of aviation transport that do not yet have transponders installed, the service supports the location of other models of the already specified manufacturers, as well as almost all helicopters, business jets, and propeller-driven aircraft.
In addition, in the coverage area of MLAT and FAA, the service receives data from absolutely all types of flying objects, regardless of the model and the presence of transponders.
The exception is flights whose information is blocked due to confidentiality and security requirements. They are not displayed on the flight map.
Flightradar in the USA
Flightradar24 is a widely used application for tracking aircraft movements, with a significant user base in the United States. The service provides real-time flight tracking information, including flight paths, aircraft types, and current positions. Users can access this information through the Flightradar24 website or mobile applications. As of now, Flightradar24 primarily offers its services in English. The interface is designed to be intuitive, allowing users to navigate and utilize the platform effectively, even without extensive language proficiency. For users who prefer to access the service in other languages, some features may be available in multiple languages, but comprehensive support in languages other than English may be limited. To assist non English speaking users, web browsers like Google Chrome offer built-in translation features. By enabling this function, users can translate web pages into their preferred language, facilitating easier access to flight tracking information. However, it's important to note that this translation applies only to the web version of Flightradar24. The mobile applications may not support this feature, and their interfaces are primarily in English. In summary, while Flightradar24 is extensively used in the United States and offers a user-friendly interface, full functionality in languages other than English is limited. Users can utilize browser translation tools for the web version to access information in their preferred language, but mobile applications may not offer the same level of language support.
Who needs Flytradar24?
It is worth using such a convenient method of tracking the location of aircraft for several reasons:
- If you are concerned about the fate of passengers on a particular flight (for example, when the weather conditions deteriorate during the flight, passing through difficult sections of the airspace, long flights during which the mobile phone is used communication is prohibited). This is the easiest way to calm your nerves while the plane with your loved ones is in the air.
- When flying to war zones, over the territory of belligerent countries, the air transport tracker is indispensable from the point of view of safety and situation control.
- If the flight is delayed for a long time in the air without announcing the reasons, you can independently make sure that everything is in order with the flight and that it is on the given route.
- For those who travel by air regularly and want to know about possible flight delays in order to plan their time. For example, if you are flying with a layover at a large air gate, and at the same time you have a limited amount of time before boarding, information about a flight delay or its imminent arrival will help you allocate the remaining time wisely.
- The mass media regularly use this resource to obtain accurate data during high-profile events, for example, during natural disasters (tsunamis, volcanic eruptions, hurricanes). So it is more convenient, firstly, to plan flights to the disaster zone, and secondly, to find out how many search vehicles are in the disaster zone or how many rescue boats have arrived for evacuation.
- For those who are interested in spotting, this resource is a source of invaluable information about the arrival of an aircraft of particular interest. Just follow the flights you are interested in right from your gadget - and watch them land or take off.
- Owners of airfreight companies can use it to track their goods in real time. Moreover, this same option can be used to rationalize the overloading of goods at airports from one transport to another. So that due to the delay in arrival, the trucks hired by you do not stand idle, and the cargo does not remain in the warehouses of the airport due to the fact that its transportation was delayed, and the next flight from the transit point took off without it.
Try it yourself and you will see that using FlightRadar is definitely worth it, both to satisfy your curiosity and to get information about what is important to you the flight took off safely and landed at the right point.
In addition, you can join the team of volunteers of the resource: Flight Radar regularly recruits newcomers to improve its network. All that is needed for this is registration as a volunteer and simple equipment, which can be ordered for just a couple of tens of US dollars. So you can feel like an important part of a global project that improves our lives every day.
Use the global capabilities of Internet services, fly at your pleasure, be calm about the fate of your loved ones who are crossing the airspace above the planet right now, get the most from just one service that works worldwide for everyone from us - FlightRadar24!
