GTS 800

An affordable 40-watt TAS traffic alerting system that is well suited to most light helicopters and piston aircraft. Features exclusive CLEAR CAS™ technology with up to 12 miles of active surveillance and ADS-B “In” capability.

Recommended for entry and mid- performance aircraft and helicopters.



GTS 825

TAS traffic alerting for faster and higher-performing aircraft. Combines active/passive surveillance, 250-watt output (for up to 40 miles of active surveillance), and Garmin CLEAR CAS™ with ADS-B “In” capability.

Recommended for mid and high-performance aircraft and helicopters.



GTS 855

Satisfies all TCAS I collision avoidance criteria for higher-capability turboprops and jets. Garmin CLEAR CAS™ enables both active and passive surveillance with 1090 MHz ADS-B “In” capability.

Recommended for very high performance turboprops and jets.

In busy, high-density airspace, pilots are challenged to "see and avoid" other aircraft that may be climbing, descending, or cruising in their vicinity. Alertness and vigilance are critical. But for added protection, nothing beats Garmin's GTS™ family of ADS-B enhanced Traffic Advisory (TAS) and Traffic Collision Avoidance (TCAS I) Systems. Featuring exclusive CLEAR CAS™ technology, these innovative systems provide accurate, dynamic traffic surveillance — with ATC-like spoken audio alerts to help you quickly respond to potential flight path encroachments.

  • Actively tracks up to 45 targets to 22 nm
  • Combines active surveillance with passive (ADS-B) surveillance
  • Generates aural and visual traffic advisories
  • Interfaces with a range of displays
  • Variety of antenna configurations

Life-saving Technology at a Money-saving Price

Feature-rich yet affordably priced, the GTS 800 system is designed to bring full TAS traffic surveillance capability well within reach of most GA pilots and their budgets. It offers power, range and performance comparable to systems costing far more. And like all our GTS devices, it will operate to 55,000 feet — so it’s not constrained by the much lower altitude limits imposed on some competitive traffic alerting systems.


Better Surveillance Equals Faster Response

Augmenting reports from radar-based air traffic control, the GTS 800 can combine both active and passive surveillance technologies (including 1090 MHz ADS-B “In”) when installed with a compatible “extended squitter” Mode-S transponder such as the GTX 330 ES unit (sold separately). Using this hybrid active/passive surveillance, the GTS 800 creates a 360° zone of detection around the aircraft — enabling you to see and identify other nearby transponder-equipped aircraft in time to take prompt corrective action. As the ADS-B NextGen system becomes available, the GTS 800 will gain enhanced surveillance features, including the ability to display flight identification, position, altitude, velocity and heading information broadcast from other NextGen-enabled transponders. Thus, instead of just seeing random targets on a display, pilots using select displays will be able to identify and track specific intruder movements using familiar TCAS-defined symbology.


It Sees More So You Worry Less

GTS 800 can track up to 45 traffic targets simultaneously — and depict up to 30 intruder threats at a time, depending on the display being utilized. Offering 40 W of transmit power, a +/- 10,000-foot vertical separation maximum, and a typical active interrogation range of 22 nm in the forward direction, the GTS 800 system will interface with a variety of compatible system displays in the cockpit. So it doesn’t require added panel space for a dedicated control/display.


Voice Alerting Helps Keep Heads Up, Eyes Out

Instead of the generic “Traffic, traffic” voice alerts of some earlier-generation systems, GTS 800’s exclusive CLEAR CAS technology provides for expanded audio messaging in an ATC-like verbal format: “Traffic. One o’clock. High (or Low or Same Altitude). Two miles.” If surveillance bearing information is not available on the intruder, “Traffic, No Bearing” is called out. By vocalizing more specific traffic­-spotting information, pilots know instantly where to look without going “eyes-down” to locate the intruder target on the cockpit display. Obviously, this can save vital split-seconds in a fast-converging traffic situation.


Antenna Options to Optimize Performance

As a value-priced TAS system, the GTS 800 offers performance, utility, and installation flexibility that’s ideally scaled for most single-engine piston aircraft. In addition to the basic TAS remote transmitter/receiver/computer LRU, GTS 800 comes standard with a single top-mounted directional antenna. Bottom-mount directional or omni antennas are also available as an extra-cost option to help optimize coverage and prevent target drop out during turns and maneuvers.
