Guide to Flight Trackers

 

 

Flight trackers are advanced devices that give us information on live air traffic all over the world. There are several sources for data received by flight trackers including radar data. All these data sources are put together with the data gathered from airlines of flight schedules and flight status data. All in all, this creates a unique flight tracking experience.

 

Automatic dependent surveillance broadcast of ADS B is the primary technology that some flight trackers use to receive flight information. This technology is best explained in the following way. An aircraft gets its location from a GPS navigation source which is a satellite. Then the ADS B transponder on the aircraft transmits a signal containing its location and other data. ADS b signals are picked up by a receiver connected to the flight tracker. This receiver feeds the data to the flight tracker and is then shown on the particular flight tracker website or flight tracker app.

 

The ADS B is a relatively new technology which is atoll being developed. Today, it is not yet really used by air traffic control. Majority of all commercial passenger aircrafts are equipped with an ADS B transponder. For general aviation, there are very few who have this. Aircrafts equipped with ADS b receivers is steadily increasing and they will become mandatory for most aircraft around the world in a few years. When mandatory, ADS B will replace primary radar as the primary surveillance method used by air traffic control.

 

One of the popular flight trackers at http://flugeverfolgen.de/ today has a network of more than 10,000 ADS B receivers around the world that receive flight information from aircrafts with ADS B transponders and send this information to the servers. Because the frequency used is high, the coverage from each receiver is limited to about 250 to 450 km in all directions depending on location. If an aircraft is flying farther away from the receiver is should fly higher to be covered by the receiver. This distance limit makes it difficult to get ADS B coverage over oceans.

 

Above 30,000 feet, which is cruising altitude, the flightradar app kostenlos tracker cover a hundred percent of Europe and of the USA. There is also good ADS-B coverage in Canada, Mexico, Caribbean, Venezuela, Colombia, Ecuador, Peru, Brazil, South Africa, Russia, Middle East, Pakistan, India, China, Taiwan, Japan, Thailand, Malaysia, Indonesia, Australia, and New Zealand. ADS b coverage varies in other parts of the world. Through the receiver, coverage is added all over the world.
