GRT Avionics Dual XGPS170 ADS-B Receiver Supplement

Section 1: Introduction

1.1 About the Dual XGPS170

The Dual XGPS170 is a 978 MHz ADS-B receiver that receives FIS-B weather and TIS-B traffic data

and displays it via USB on GRT Horizon HX, HXr and Sport SX EFIS screens. It also transmits data

through Bluetooth to Android and Apple tablets and phones that can display ADS-B information.

NOTE: GRT Horizon/Sport HS and WS units do not support USB receivers, including Dual XGPS170.

These systems require a receiver with RS-232 serial output.

WARNING: The Dual XGPS170 is a receiver ONLY. Do not expect or rely on any traffic information

unless your aircraft is also participating in ADS-B OUT. GRT recommends the use of an ADS-B

compliant Mode S extended-squitter transponder, such as the Trig TT22, coupled with WAAS GPS

for full ADS-B participation. Please read the ADS-B page on the GRT website for more information

on current ADS-B options and how the system works.

Follow all instructions in the Dual XGPS170 owner’s manual thoroughly. This supplement is intended

to support GRT users with information about connection and use with GRT EFIS systems, and may

not be totally up-to-date with all Dual specifications.

The interface between this receiver and GRT display units allows for:

Ÿ FIS-B subscription-free weather information displayed on a GRT display unit while within ADS-B

ground coverage;

Ÿ TIS-B traffic information displayed on a GRT display unit while within ADS-B ground coverage;

Ÿ Direct airplane- to-airplane traffic information displayed on a GRT display unit from nearby aircraft

participating in ADS-B OUT on 978 MHz UAT frequencies.
