1090 MHz ADSB LNA Low Noise Amplifier Circuit Board Picture
What is the basic principle of ADS-B?
The aircraft’s onboard ADS-B communication equipment sends out the collected data in the form of broadcasts, receives broadcasts from other aircraft or from the ground, and then processes them and passes them to the cockpit integrated information display.
Based on the collected ADS-B information from other aircraft and ground, onboard radar information, and navigation information, the cockpit IID provides the pilot with situational information about the aircraft and other additional information so that air traffic controllers can accurately track the aircraft.
Based on the direction of information transfer relative to the aircraft, the airborne ADS-B application functions can be divided into two categories: transmitting (OUT) and receiving (IN).
ADS-B OUT
As the name implies, OUT means outward, which is the original intention of ADS-B and is the basic function of airborne ADS-B equipment.
The aircraft onboard device keeps broadcasting position and other information outward like a radio, regardless of other users’ status: including aircraft equipment information (ID), position, altitude, speed, direction, climb rate, etc.
Ground systems monitor air traffic conditions by receiving ADS-B OUT information from airborne equipment, playing a role similar to that of radar.
Airborne ADS-B equipment constantly OUT position data, so what is the main source of position data?
The horizontal position of the aircraft generally comes from the GNSS system, and the altitude data comes from the aircraft’s barometric altimeter.
Therefore, the positioning accuracy of the GNSS system determines the positioning accuracy of ADS-B. The positioning accuracy of the GNSS system can reach the order of 10 meters, so the positioning resolution of ADS-B can also reach the order of 10 meters.
The radar equipment, on the other hand, has relatively low monitoring accuracy because of the inherent angular resolution limitation, and cannot distinguish aircraft that are too close.
ADS-B IN
IN means inward, which is an advanced function of airborne ADS-B equipment.
With this function, the aircraft can not only broadcast its own information to the surrounding area, but also receive information from other aircraft or ground service equipment, and display it to the cockpit traffic information display device (CDTI) so that the crew can feel the operation status of other aircraft in the surrounding area, thus improving the crew’s air traffic scenario awareness.
