Over the next few years, the technology we use to keep aircraft safely separated in ATC airspace will undergo a significant
transformation. Instead of relying on ground-based radar as the primary means of identifying and monitoring aircraft, the NextGen
operational environment will adopt an interactive system of GPS-based datalinks to perform this tracking function more accurately,
reliably and affordably.

User’s signal reception range may vary depending on receiver altitude above ground and any intervening physical obstructions to line of sight uplink.
Called ADS-B (an acronym for “Automatic Dependent Surveillance – Broadcast”),
this space-based, satellite-derived system will allow ATC to handle a larger
volume of airplanes more efficiently – while providing broader coverage over
areas that were not possible (or practical) to support via radar service before.
Using ADS-B datalinks, each aircraft will automatically transmit its precise
position, track, speed, altitude, climb/descent rate, etc., to air traffic controllers
and other nearby aircraft using the network. The “dependent” part of ADS-B
means that, instead of being passively tracked by ATC, each aircraft operating
in the system will ultimately be responsible for determining its own WAAS/
SBAS-level GPS position and then transmitting that information to others using
the datalink network. The idea is that everyone in the ADS-B loop is working
with, and dependent on, the same interconnected information – which allows
them to share, see and react to the same tactical air traffic scenarios. Situational
awareness is clearly enhanced – as long as substantially all aircraft operating in
the airspace are equipped to participate in the exchange of ADS-B data. To
make that happen, NextGen rulemaking provides that all aircraft operating in
controlled U.S. airspace where a Mode C or Mode S transponder is now required
will need to be equipped with ADS-B “Out” capability by December 31, 2019.
(See requirements and deadlines for other ADS-B adopting airspace regions
on the overleaf of this brochure). It’s important to emphasize that under the
new U.S. regulations only ADS-B “Out” transmission is required. There is
currently no regulatory requirement for ADS-B “In”. Thus, for many pilots, a
minimal-but-workable solution for meeting the new ADS-B “Out” requirement
is to link a certified WAAS GPS receiver with a 1090 MHz Mode S transponder
with ES (or “extended squitter”) capability for transmitting the aircraft’s
position-tracking data into the network. This combination will meet the NextGen
equipage rules and allow flight at any altitude, but it won’t provide you with
the displayed in-cockpit user benefits of ADS-B. For that, you need ADS-B “In”
capability – which receives the networked tracking data and enables you to
view, on a compatible cockpit display or portable device, the same basic traffic
picture that ground controllers are monitoring on their scopes. There’s also a
TIS-B traffic uplink component available to help fill the gaps in traffic coverage
from not-yet-ADS-B-compliant aircraft or those either equipping with only ES
or only UAT solutions. The TIS-B broadcast service uses ATC-derived radar
surveillance (from transponder-equipped aircraft), which is uplinked from the
ground to supplement the ADS-B traffic picture in situations where nearby
aircraft may not all yet be equipped with ADS-B “Out” transmitters. In addition
to displaying traffic, adding ADS-B “In” can also provide access to uplinked
(and subscription-free) aviation weather. The weather content available on this
FIS-B uplink is comparable to the basic services offered by leading commercial
TAFs, winds and temperatures aloft, PIREPs, NOTAMs, and more. However,
these ADS-B “added value” weather features can only be accessed with certain
types of ADS-B “In” receivers. Not all ADS-B “In” formats are compatible with
the free FIS-B weather uplinks.

While every jurisdiction outside the U.S. has instituted a single 1090 MHz frequency for ADS-B datalink, operators within the U.S. airspace system will have two approved options that can satisfy the mandate for ADS-B “Out” airborne equipment. One option, as mentioned earlier, is the 1090 MHz Extended Squitter (or ES) format available on certain Mode S transponders. The extended squitter technology enables the transponder to serve as a broadcast datalink – transmitting the aircraft’s flight ID, GPS position, altitude, velocity, and other information to controllers and other nearby aircraft. (Traditional Mode S and Mode C transponders can only respond to radar interrogations with basic identity and altitude information; thus, they require ground-based radar surveillance to correlate and track the aircraft’s position.) To help relieve frequency congestion on the transponder’s 1090 MHz band, the FAA decided to offer a second ADS-B frequency option. This one, operating at 978 MHz, is called the universal access transceiver, or UAT. Combining both ADS-B “Out” and “In” capability in a single transceiver, the UAT can be used to provide pilots with a display of both air-to-air and TIS-B uplinked traffic data in the cockpit. Further, only UAT equipment has the capability to offer the subscription-free FIS-B service for uplinked NEXRAD weather and other flight information (such as TFRs, NOTAMs, PIREPs, etc.). The 1090 MHz ES system does not have the datalink capacity for FIS-B weather/data support.
This free FIS-B weather uplink on UAT was conceived as a “value added” proposition to encourage owners of GA aircraft that typically operate below 18,000 feet to go with a 978 MHz solution for ADS-B. (Otherwise, all aircraft that operate at or above 18,000 feet are required to have the 1090 MHz ES datalink.)
However, with two discrete frequency options, there can be situations where aircraft may be operating beyond the range of a ground station uplink – and are thus relying on air-to-air datalinks between aircraft for their traffic picture. In such cases, a 1090 ES MHz equipped aircraft would not display as traffic to a pilot equipped with a single-link 978 MHz UAT solution. Consequently, both pilots may think they’re seeing a complete traffic picture, when, in reality, they may not be.
So, what’s the solution? Consider a “dual-link” ADS-B: One that can listen on both 1090 MHz and 978 MHz UAT frequencies. That way, there’s no uncertainty. Your equipment is able to link with either datalink format within air-to-air range, enabling you to always see other ADS-B traffic in your vicinity, regardless of ground station uplink coverage. By covering both of the available ADS-B frequencies, Garmin’s dual-link ADS-B solutions offer a more complete situational picture – for added confidence in all phases of flight.

The GDL 84 ADS-B datalink provides an all-inclusive, convenient and minimally intrusive means to satisfy the requirements of NextGen at an affordable price. The GDL 84 comes complete with an integrated WAAS GPS, installation kit, configuration module and GPS antenna, and the only panel modification required during installation is a single annunciator indicating ADS-B status.
The GDL 84 receives air-to-air traffic data from 1090 ES and 978 UAT links, regardless of ground station coverage. It also provides TargetTrend™ relative motion tracking technology, spoken audio alerts and AutoSquawk – and it delivers subscription-free FIS-B NEXRAD radar, forecasts and more.
But the GDL 84 delivers all the benefits offered by ADS-B In without needing to add a multifunction display. With a Garmin Flight Stream wireless gateway, it transmits ADS-B traffic and subscription-free weather to a Garmin portable or mobile device running the Garmin Pilot™ app.
Engineered for the FAA’s NextGen ATC environment, Garmin’s GDL 88 is your all-purpose “dual-link” installed solution for ADS-B compliance on aircraft that operate below 18,000 feet. Available with or without1 a built-in WAAS GPS receiver, the GDL 88 can interface with a variety of Garmin cockpit displays. And since it features both ADS-B “In and Out” capability, you can use it to immediately start taking advantage of the FAA’s U.S. uplink infrastructure that provides subscription-free FIS-B weather as well as TIS-B traffic information to your cockpit. On the weather side, you’ll see content comparable to the basic subscription services offered by today’s leading satellite weather providers: NEXRAD imagery, METARs, TAFs, PIREPs, and more. Plus, on the traffic side, the GDL 88 also receives air-to-air data on both 1090 ES and 978 UAT links, enabling you to always see other ADS-B traffic2 in your vicinity, regardless of ground station coverage. Spoken audio alerts (“Traffic. Two o’clock. High. Two miles.”) combine with Garmin’s new TargetTrend™ relative motion tracking technology to offer a faster, more intuitive way of judging target trajectories and closing rates in relation to your aircraft’s position2. And with TerminalTraffic™, the GDL 88 provides pilots with the most comprehensive picture of ADS-B-equipped aircraft and ground vehicles in the airport environment. What’s more the GDL 88 uses AutoSquawk technology, which allows it to automatically synchronize with your on-board transponder’s squawk code, and then transmit that data through its own datalink. Not only does this provide a single point of data entry for ADS-B “Out”, but it also allows you to meet the new regulations – under 978 MHz UAT rules – without the need to replace or upgrade your existing transponder to provide ES (extended squitter) functionality. Thus, Garmin’s GDL 88 helps make your path to ADS-B compliance as simple, straightforward and cost-effective as it can possibly be.

In busy, high-density airspace, you need every possible advantage when it comes to “seeing and avoiding” traffic conflicts. That’s why Garmin developed the GTS™ family of ADS-B enhanced Traffic Advisory (TAS) and Traffic Collision Avoidance (TCAS I and II) Systems. For aircraft flying outside ADS-B surveillance-enabled airspace, an active traffic system like the GTS series will remain the primary source available to display electronic traffic information. In addition, when paired with an ADS-B “In” solution like the Garmin GDL 88, the GTS series provides the most complete traffic picture possible: showing targets for all aircraft – including those not yet equipped for ADS-B “Out”. Featuring exclusive Garmin CLEAR CAS™ (Correlated Location Enhanced ADS-B Receiver Collision Avoidance System) technology, these attractively priced Garmin GTS systems combine both active and passive surveillance, including 1090 MHz ADS-B “In”, to correlate target data and pinpoint traffic threats. Three distinct product configurations are available: GTS 800, GTS 825 and GTS 855. The GTS 800 TAS system offers up to 22 nm of interrogation range, while the higher-power GTS 825 TAS and GTS 855 TCAS I systems reach even further (up to 40 nm of interrogation range with the GTS 825; up to 80 nm with the GTS 855). All three systems use surveillance data from nearby transponder-equipped aircraft to generate expanded audio callouts of traffic in an ATC-like spoken format. The systems can also display traffic symbols and advisories on a variety of compatible navigation or multi-function display products. Passive surveillance with ADS-B “In” capability is available with installation of Garmin’s GTX 33 ES or GTX 330 ES transponders or other compliant ADS-B equipment, such as Garmin’s Dual-Link GDL 88 (1090/978 Mhz). On the GTS 825/855 systems, up to 75 traffic targets can be tracked simultaneously, with up to 30 intruder threats being displayed at a time. And, thanks to Garmin’s expanded voice alerts, pilots know instantly where to look outside for called traffic – thus saving vital time when traffic is converging quickly.
For 1090 MHz ADS-B “Out” signal delivery that meets worldwide ADS-B requirements – including current TSO-C166b standards in the U.S. for flight at any altitude (required above 18,000 feet) – Garmin’s Extended Squitter (ES) capable GTX 330, GTX 33 and GTX 23 series transponders offer a logical, affordable pathway to NextGen compliance. They can interface with approved GPS position sources, such as Garmin’s GTN and WAAS GNS series navigators, for ADS-B “Out”. Then, for full ADS-B “In” capability, they can also be paired with the Garmin GDL 88 receiver and compatible cockpit displays to enable both visual traffic monitoring and access to subscription-free weather. The transponders’ extended squitter technology enables the GTX 330/33/23 series to automatically transmit all essential traffic surveillance data – including aircraft flight ID, position, altitude, velocity, climb/descent, and heading information. Moreover, for customers who have already purchased a Garmin GTX 330/33 series transponder, there’s a factory upgrade available to add the ES functionality. The Garmin GTX 33 is a remote-mount unit designed for use with the GTN 650/750 and G1000® series avionics, which allow for built-in transponder mode and code selection. The GTX 330 is a panel-mount unit. Another option, the Garmin GTX 23 ES is designed for the experimental and light sport (LSA) market. It provides an affordable transponder/datalink combo for Garmin’s popular G3X glass flight display system. And when paired with an approved GPS position source, it meets the criteria for a 1090 MHz ADS-B “Out” installation. All three of these Garmin ES capable transponders are fully solid-state designs – delivering 250 watts of power output, while minimizing heat emissions and power consumption to give you superior reliability and extra-long service life.

Built to meet the unique and stringent demands encountered by helicopter operators, and designed providing them with a timely solution to meet airspace modernization initiatives, the GDL 84H and GDL 88H offer ADS-B Out solutions, while also providing ADS-B In tools on compatible cockpit displays and mobile devices.
The GDL 84H and GDL 88H provide all the industry leading ADS-B In technology provided by fixed-wing models of these datalinks, plus they offer safety enhancing benefits specifically for helicopters. TargetTrend™ relative motion technology offers a faster, more intuitive way of judging target trajectories and closure rates in relation to your aircraft’s position. As part of Garmin’s Terminal Safety Suite, TerminalTraffic™ provides pilots with the most comprehensive picture of ADS-B-equipped aircraft and ground vehicles in the airport environment. ADS-B-equipped aircraft in-flight are easily distinguished from ground vehicles and taxiing aircraft, which are displayed using distinct colors and symbols, and all of this information is presented on a simple, easy to understand SafeTaxi® diagram with reference to runways, taxiways hangar locations and more. Additionally, when configured for helicopter operations, TerminalTraffic™ helps pilots easily identify potential traffic conflicts while in the airport environment by minimizing nuisance alerts from fixed-wing aircraft and abbreviating select alerts while performing unique helicopter maneuvers such as hovering. And by pairing a GDL 88H with Garmin GTN series touchscreen navigators, On Scene mode reduces nuisance alerts when intentionally operating in close proximity to other helicopters, such as during electronic news gathering, alerting you only when new threats are present.
The GDL 84H and GDL 88H also give you a wide range of display choices to receive these safety and operational benefits. The GDL 88H conveniently interfaces with the GTN touchscreen series or GNS WAAS navigators to display ADS-B traffic and weather in the cockpit. And if you don’t have a compatible display, both can wirelessly transmit weather and traffic information to a mobile device using Garmin Pilot app. Additionally, for helicopters that do not already have an approved WAAS position source, the GDL 84H comes with WAAS and GDL 88H is optionally equipped with a built-in WAAS GPS receiver.

If you’re looking for an easy and affordable way to bring all the free benefits of ADS-B uplinks to your cockpit, this is your answer: Just plug the GDL® 39 3D dual-link portable receiver into your aircraft’s cigarette lighter outlet – or clip on the optional Lithium-Ion battery pack – and you’re ready to connect with the subscription-free U.S. graphical weather and traffic information now available through the FAA’s 978 MHz ADS-B datalink. NEXRAD imagery, METARs, TAFs, PIREPs, and more: The uplinked weather content is continuously broadcast from a network of ground stations, and is similar to the basic services offered by leading commercial satellite weather providers. In addition, you’ll also receive ADS-B traffic information and target alerts to help you maintain safe separation. Spoken audio alerts call out potential flight path conflicts (“Traffic, traffic.”) to get you looking right away. Meanwhile, on your compatible screen, Garmin’s TargetTrend™ relative motion display2 offers a faster, more intuitive way of judging target trajectories and closure rates in relation to your aircraft’s flight path. Accessing both 1090 ES and 978 UAT frequency bands, the dual-link GDL 39 can show you a complete air-to-air picture of other ADS-B “Out” equipped aircraft
in your vicinity – regardless of the ground station coverage where you’re flying. And with TerminalTraffic™, you’ll see ADS- B-equipped aircraft and ground vehicles in the airport environment. You can view all this data on select Garmin portable units – including the aera 796/795, aera 500 series, and GPSMAP 696/695. In addition, the 796/795 will also display 3D Vision with AHRS attitude display cues provided by the GDL 39 3D. This versatile datalink can also be used to provide
enhanced GPS location information and AHRS backup attitude sensor reference to your Apple iPad® or other iOS® or Android-based devices compatible with our Garmin Pilot™ mobile app. This provides your device with the precision and performance you’d expect from Garmin’s aviation-grade navigation products – combining WAAS-quality positioning accuracy with 5-times-per-second updating capability. And you can even split the display on your iPad® screen to show traffic and weather overlaid on the moving map above, while monitoring your backup AHRS attitude on Garmin’s Panel Page instrument display below. The GDL 39 3D:
Any way you look at it, this is one smart, simple, affordable way to provide ADS-B “In” capability – and more – to your cockpit.
Note: The GDL 39 is a non-certified receive-only product. It does not provide ADS-B “Out” capability to satisfy NextGen requirements. However, it can serve as an affordable ADS-B “In” solution for subscription-free access to the FAA’s weather and traffic uplink services. If your aircraft isn’t transmitting ADS-B “Out” data to trigger FAA ground station uplink, then the TIS-B data received may be incomplete for your aircraft.
