ADS-B, or Automatic Dependent Surveillance - Broadcast, is a technology used in aircraft for transmitting and receiving information to and from other aircraft and ground stations. A typical ADS-B system consists of a transponder and a GPS receiver.
The following specifications outline the main features and requirements of an ADS-B transponder with included receiver:
Transmission Frequency: The ADS-B transponder must transmit on the frequency of 1090 MHz.
Transmission Rate: The transponder must transmit data at a rate of at least once every second.
Transmission Content: The transponder must transmit the aircraft's position, altitude, velocity, and other information that could be relevant to air traffic control.
GPS Receiver: The ADS-B system must include a GPS receiver to determine the aircraft's position and velocity.
Power Supply: The transponder must be powered by the aircraft's electrical system or an external power source.
Certification: The ADS-B transponder must be certified by the relevant regulatory agency, such as the Federal Aviation Administration (FAA) in the United States, to ensure it meets all necessary safety and performance standards.
Compatibility: The ADS-B transponder must be compatible with existing air traffic control systems, including ground-based receivers and displays.
Reliability: The transponder must be designed to operate reliably in all weather conditions and under a variety of operational scenarios, including high-altitude flights and dense air traffic environments.
Security: The ADS-B transponder must include appropriate security features to prevent unauthorized access and ensure the integrity of the transmitted data. This may include encryption and authentication mechanisms.
User Interface: The ADS-B transponder may include a user interface, such as a display or control panel, to allow pilots to monitor and adjust system settings as needed.
