The Lynx MultiLink Surveillance System is a Mode S Level 2 dens Class 1 Transponder with an integrated GPS receiver providing Automatic Dependent Surveillance-Broadcast (ADS-B) out on 1090 MHz. The unit also receives ADS-B data via 978 MHz and 1090 MHz. Some models support optional Active Traffic Awareness System (TAS) or antenna Diversity functionality.

The unit replies to Mode A, Mode C and Mode S interrogations on 1030 MHz and replies on 1090 MHz. The unit is equipped with IDENT capability that activates the Special Identification (SPI) pulse for 18 seconds.

Ground stations and airborne TCAS can interrogate Mode S Transponders individually using a 24- bit ICAO Mode S address, which is unique to the particular aircraft. In addition, ground stations may interrogate the unit for its transponder data capability and the aircraft's Flight ID.

The ADS-B provides own aircraft data with Enhanced Visual Acquisition (EVAcq) traffic information that improves situational awareness and flight safety by providing aircraft position, velocity, and heading information that is automatically transmitted to other aircraft and ground stations providing immediate surveillance of air-to-air traffic. 

The ADS-B system has the following capabilities:

·                1090ES In (1090MHz) - Receive ADS-B, ADS-R and TIS-B

·                1090ES Out (1090MHz) - Transmit ADS-B

·                UAT In (978MHz) - Receives ADS-B, ADS-R and TIS-B, FIS-B, NOTAMS, and TFR’s 

The unit also provides TAS traffic advisories when TAS configuration is enabled. A voice audio output announces relative altitude and traffic alerts. The unit has multiple transmit/receive ARINC 429, RS-422 and RS-232 data ports used to transmit data to traffic, weather, and PED displays. 

The unit provides the transponder code, reply symbol and mode of operation to the display. 

Maintenance and configuration setup can be accomplished via the USB port located on the front of the unit or by an optional WiFi connection.
