The decision to utilize the UAT data link for general aviation (GA) in the United States is influenced by the congested nature of the 1090 MHz frequency band. With a high volume of both air carrier and GA aircraft, as well as numerous radar installations, the 1090 MHz frequency can become...

The RF transmitter may be configured to operate at a frequency within the L-band Digital Aeronautical Communications System (LDACS) frequency band. For example, the controller may be configured to encapsulate the flight identification data and flight position data within a message for an LDACS.SHAWN...
A "ground station" can be built from any Helium Hotspot without affecting the performance, nor do we utilize the LoRa Concentrator (ADS-B is broadcast over the 1090MHz frequency). To achieve dual "mining" it is simply a case of running DeFli in a Docker Container (can be viewed on our...
And ADS-B is one type of signal that people really have fun trying to optimize. For ADS-B it’s very desirable to have the filtering placed AFTER the LNA, because of the high insertion loss degradation that a sharp filter can bring at the ADS-B L-band frequency. But then the problem...
A system and method of using a standard ADS-B transmitter and encoder to identify targets to provide a collision avoidance system, wherein the method includes the steps of providing a standard ADS-B transmitter and encoder, a phase modulator including a digital synthesizer, radio-frequency electron...

Since 1090 MHz is being used to support all transponder interrogations and TCAS traffic alerting, as well as ADS-B transmissions, there exists the potential for frequency congestion as airspace traffic continues to grow. To help alleviate crowding on the 1090 MHz band, the FAA decided in 2002...
the method includes the steps of providing a standard ADS-B transmitter and encoder (20), a phase modulator (30), including a digital synthesizer (31), radio-frequency electronics (40), antennas (50), and a radar transceiver (70), synthesizing digital-based band signals from the ADS-B ...
