1.2.2 Transponder Functional Overview
The unit receives 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.
1.2.3 GPS Functional Overview
The GPS function utilizes signals from Global Positioning System (GPS) satellite constellation and
Satellite-Based Augmentation Systems (SBAS) such as the USA Wide Area Augmentation System
(WAAS), European EGNOS, Indian GAGAN, and the Japanese MSAS. Currently it supports WAAS and
WAAS compatible SBAS systems.
The internal GPS function provides position, velocity, time, and integrity (NIC, NACp, etc.) information to
the ADS-B functions and meets the requirements of 14 CFR 91.227.
1.2.4 Lightning Detection (optional)
Release 2.1 and later. The WX-500 Stormscope is a Weather Mapping System that provides lightning
discharge information. This information is shown on the right application screen of the NGT-9000 Panel
Mount unit.
1.2.5 ADS-B System Overview
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) - Receive ADS-B, ADS-R, TIS-B, and FIS-B data
The Automatic Dependent Surveillance-Broadcast (ADS-B) improves situational awareness and flight
safety by providing real time traffic information. The ADS-B In function is used to receive ground station
supported TIS-B and ADS-R traffic, and direct communication with ADS-B out equipped aircraft.
The ADS-B Out (1090MHz) function is used to periodically broadcast (without interrogation)
information about the aircraft that includes aircraft identification, position, altitude, velocity and other
aircraft status information.
The Automatic Dependent Surveillance Re-broadcast (ADS-R) is a ground based broadcast service that
repeats ADS-B messages from one link (1090ES or UAT) to the other link for aircraft with ADS-B In.
Traffic Information Service Broadcast (TIS-B) is a ground based broadcast service that provides
secondary surveillance radar (SSR) derived traffic data (ATC transponder equipped aircraft not equipped
with ADS-B Out capability) to ADS-B In equipped aircraft.
