1.2 FUNCTIONAL DESCRIPTION
The Lynx MultiLink Surveillance System (also referred to in this manual as the Lynx NGT-9000s) is a
Mode S Level 2 dens Class 1 Transponder with an integrated GPS receiver providing Automatic
Dependent Surveillance-Broadcast (ADS-B) output using a 1090ES (Extended Squitter). The unit also
receives ADS-B data via 1090ES and UAT (978 MHz Universal Access Transceiver). 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 receiving interrogations at 1030 MHz and
transmitting responses at 1090 MHz. The unit is equipped with IDENT capabil ity tha t activat es the
Special Identification (SPI) pulse for 18 seconds.
Ground stations 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 1090ES and UAT ADS-B datalink have the following capabilities:
• 1090ES In - Receive ADS-B, ADS-R and TIS-B
• 1090ES Out - Transmit ADS-B
• UAT In - Receives ADS-B, ADS-R and TIS-B, FIS-B, NOTAMS, and TFR’s
The unit also provides TAS traffic adviso r ie s w hen TAS configuration is enabled. A voice or tone audio
output announces traffic alerts. The unit has multiple transmit/receive ARINC 429, RS-422 and RS-232
data ports used to transmit data to traffic, weather, an d PED display s.
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.
Models are available that provide Active Traffic Awareness System (TAS) function and antenna
Diversity. Both models require additional equipment to be installed.
1.2.1 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, NAC etc.) information to
the ADS-B functions and is ADS-B rule compliant with the requirements of AC20-165A.

1.2.2 ADS-B System Overview
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 nearby like equipped aircraft (with
Mode S or UAT). The ADS-B Out (1090ES) function is used to periodically broadcast (without
interrogation) information about the aircraft that includes aircra ft id en ti fi c a tion, position, al ti tu de , ve loc ity
and other aircraft status information.
•The traffic display shows the relative position of ADS-B or standard traffic using text, shapes, and
colors. ADS-B also provides similar information on ADS-B equipped ground vehicles.
•The effective surveillance range is 60 nmi. The passive-mode surveillance range is 160 nmi and
maintains report messages for a minimum of 200 1090ES ADS-B participants and 300 UAT ADS-B
participants simultaneously. To reduce display clutter a set number of other aircraft of the highest
priority other aircraft are displayed at a time. See Figure 1-2 for an example of own aircraft traffic
(UAT, 1090ES, TIS-B, and TAS).
•The Lynx NGT-9000 is equipped with a dual-link receiver. ADS-R service is unnecessary to provide
a complete picture of traffic in the area.
1.2.3 ADS-RSystem Overview
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.
•ADS-R transmissions are updated at least every 2 seconds on the surface, 5 seconds in the term ina l
area, and 10 seconds in the en-route airspace.
•An aircraft on the ground receiving ADS-R is provided both ground aircraft and vehicles as well as
airborne other aircraft within 5nm and 2,000 ft above ground level of the airport reference point.
•Other aircraft are provided by the ground station if within a 15 nm horizontal range and +/-5,000 ft
of altitude of the receiving aircraft. ADS-B equipped ground aircraft and vehicles are not displayed
to airborne aircraft. See Figure 1-2 for an example of own aircraft traffic (UAT, 1090ES, TIS-B, and
TAS).
1.2.4 TIS-B System Overview
Traffic Information Service Broadcast (TIS-B) is a ground based broadcast service that provides
secondary surveillance radar (SSR) derived traffic data (aircraft not equipped with ADS-B Out capability)
to ADS-B In equipped aircraft.
•The actual availability of services depends upon the availability of ground-based radar to support
TIS-B source data.
•Receiving aircraft must be in both radar coverage and ground based transceiver (GBT) coverage in a
given area to receive TIS-B service in that area. When ownship is above 24,000 ft, the ground station
will no longer provide TIS-B service. To reduce display clutter, the TIS-B service provides traf fic
information on other aircraft within 15 nmi and +/- 3500 ft of ownship.
•Other aircraft are provided by the ground station if within a 15nm horizontal range and +/-3,500 ft of
altitude of the receiving aircraft. ADS-B equipped ground aircraft and vehicles are not displayed to
airborne aircraft. See Figure 1-2 for an example of own aircraft traffic (UAT, 1090ES, TIS-B, and
TAS).

Installation Manual
1.2.5 FIS-B System Overview
The Flight Information Services - Broadcast (FIS-B) function provides pilots with a cockpit display of
certain aviation weather and aeronautical information for awareness of own aircraft location with respect
to reported weather, including hazardous meteorological conditions (CONUS/ NEXRAD /AIRMETS/
SIGMETS/ NOTAMS/ METARS, etc) and SUA status and TAF (FIS-B products).
NOTE
CONUS and Regional NEXRAD may not always contain complete data.
The data is refreshed every 15 minutes and it is likely to be updated in a
future cycle.
FIS-B is advisory information only and is intended to enhance pilot decision-making during strategic
flight planning. FIS-B augments traditional sources of this information such as ATC and Flight Service
Station (FSS). FIS-B information is provided over the ADS-B Services network on the 978 MHz UAT
link when in ground station coverage.
1.2.6 Traffic Awareness System (option) Overview
The TAS option is an active system that operates as an aircraft-to-aircraft interrogation device. The unit
interrogates transponders in the surrounding airspace similar to ground based radar. When rep lies to these
active interrogations are received, the responding aircraft’s range, altitude, and closure rates are computed
to plot traffic location and predict collision threats. The unit alerts the flight crew to nearby transponder
equipped aircraft and assists the pilot in the visual acquisition of aircraft that may represent a danger.
Traffic information, out to a selected range, is graphically displayed on the unit or alternate display. See
Figure 1-2 for an example of own aircraft traffic (UAT, 1090ES, TIS-B, and TAS).
•The system display shows the relative position of traffic using text, shapes (i.e., Traffic Advisory =
solid circle; Other Traffic = open diamond) and colors.
•The effective active-mode surveillance range is 35 nmi and track 35 ATCRBS intruders
simultaneously with the target bearing relative to the nose of own aircraft.
•The tracking of targets is in a cylindrical volume centered on own aircraft that has, at a minimum, a
radius of 35 nmi and extends 10,000 ft above and 10,000 ft below own aircraft.
1.2.7 Discrete Inputs and Outputs
The Lynx NGT-9000s have discrete inputs and outputs available that can be interfaced to indi cat or lam ps
and cockpit switches. These are optional installations and are not required.
•The WOW input discrete signals the On Ground status to the unit via a squat switch, airspeed
monitor, or a collective switch.
•The IDENT switch activates the IDENT pulse which highlights the aircraft’s symbol on the ATC’s
radar screen and is identified on the NGT-9000 when active.
•The Audio Mute switch is used to signal the unit to suppress all audio output. The discrete is set to
GND/Open. The active position indicates Audio Muted. When grounded this input mutes all audio
from the NGT-9000. This input is typically only used if the aircraft equipped with TAWS or other
aircraft alerting systems.
•The TAS Alert lamp is used to indica te Tra f fi c Ale rt ( TA ). Th e dis c re te is set to G N D /O pen . The
GND (active) position indicates Traffic Alert. The GND (active) position illuminates the lamp.
•The TIS-B Not In Coverage lamp is used to indicate that the unit is not receiving a ground station
signal. The discrete is set to GND/Open. The GND (active) position illuminates the lamp.
•The ADS-B Out Fail lamp is used to indicate that ADS -B out is not operating. The discrete is set to
GND/Open. The GND (active) position illuminates the lamp. Depending on the situation the lamp
has the following functions: flashes while the GPS is initializing and stays illuminated when the
ADS-B Out has failed.

1.4.4 Audio Out
Two audio out discrete outputs are available that can output a 40 mW signal to equipment with a load of
600 Ohms.
1.4.5 RF Suppression Input/output
The mutual suppression input/output is used to provide suppression of L-band equipment on the aircraft.
The transponder uses the signal as an input to inhibit decoding of receiver signals when other equipment
on the aircraft is transmitting. When the transponder transmits, it asserts a positive voltage on the output
to provide the suppression to other systems on the airplane.
1.4.6 TAS Alert
Traffic Alert is a discrete output that provides an indication of when a TAS Alert exists. Discrete outputs
are ground/open type and are able to sink 250mA.
1.4.7 TIS-B Not In Coverage
The TIS-B Not In Coverage discrete output provides an indication that the unit is not in an Radar
coverage area or that power has been removed from the unit. Discrete outputs are ground/open type and
are able to sink 250mA.
1.4.8 WiFi Interface
The Unit uses a RS-232 bus to interface with a commercially available RS-232 to Wifi accessory. This
interface provides traffic and weather information on a personal electronic device via an approved
software application (APP).
1.4.9 WOW Input
The WOW input discrete is optional. The input signals the On Ground status to the unit via squat switch,
Airspeed monitor, or a collective switch. The discrete input is active (ON) when the input is grounded.
• Do not connect this to a gear switch or a manual pilot switch input.
• An internal algorithmic override that uses ground speed and altitude inputs may override this input
and change the air/ground state (ex. a WOW "in-air" state could get changed back to on ground if the
Aircraft is sitting on the ground). This is expected behavior. If simulated in-air tested is requir ed,
use the ground test mode.
1.4.10 Maintenance Interface
The Unit can interface to a maintenance computer using either the WiFi interface or the USB port located
on the front of the unit. This interface is used for installation setup and fault isolation and is only available
while on ground.
1.4.11 GPS Antenna
Antenna performance is critical to the operation of the Unit. The unit requires that the GPS Antenna meet
performance requirements s peci fi ed in TSO-145c.
