Introduction to Flightradar24 and Blue Planes
Flightradar24 is a Swedish-based company that offers a unique service, enabling users to track flights in real-time. The platform relies on a network of ADS-B (Automatic Dependent Surveillance-Broadcast) receivers, which collect data from aircraft equipped with ADS-B transponders. This data is then used to calculate the aircraft’s position, altitude, and velocity. The resulting information is displayed on a map, providing users with a comprehensive overview of air traffic.
On the Flightradar24 map, aircraft are represented by different colored icons, with blue planes being one of the most intriguing. Blue planes on Flightradar24 indicate that an aircraft is transmitting its position via ADS-B, but the signal is not being received directly by Flightradar24’s network of receivers. Instead, the data is being relayed through other means, such as satellite connections or third-party feeds.
Understanding ADS-B and Its Role in Blue Planes
ADS-B is a crucial component in the functioning of Flightradar24 and the appearance of blue planes. ADS-B is a surveillance technology that enables aircraft to broadcast their position, altitude, and velocity to nearby receivers. This information is then used to track the aircraft’s movement and provide real-time updates.
There are two types of ADS-B systems: ADS-B Out and ADS-B In. ADS-B Out transmits the aircraft’s position and other data to nearby receivers, while ADS-B In receives this data and provides it to the aircraft’s cockpit. The majority of commercial aircraft are equipped with ADS-B Out, which allows them to transmit their position to air traffic control and other nearby aircraft.
