Chapter 2. Introduction
This guide describes the maintenance of the Apollo GX line of products. The GX50 and GX55 are
GPS receivers. The GX60/65 models combine the GPS receiver with a VHF radio in a single
package.
The Apollo GX products are high-performance GPS products with a high-resolution moving map
display configured in a 2-inch high by 6.25-inch wide standard package. The Apollo GX’s use a
powerful, accurate 8-channel GPS engine designed specifically for high-performance aviation use.
The 160 by 80 pixel electroluminescent display uses an automatic intensity control to keep it easily
readable in all conditions from direct sunlight to the dark of night.
A wealth of easy to use features serves the needs of today’s demanding aviation requirements. The
large waypoint database has information about airports, VORs, NDBs, intersections, and special use
airspaces that makes the Apollo GX an encyclopedia of aviation. It’s what you’d expect from UPS
Aviation Technologies the first to provide a database in a general aviation navigation aid. The
database can be updated by simply changing the removable data card in the front of the unit. The
database can also include 500 custom waypoints created by the user. Thirty flight plans can be saved
with up to twenty legs for setting up custom tailored routes. The detailed navigation information
displays are also customizable and can be set to automatically scroll through the desired information.
The Nearest/Emergency Search feature, invented by UPS Aviation Technologies, makes it easy to
react to an emergency or change your active flight plan.
GX55
The GX55 is designed to be a simple slide-in replacement for panel-mounted Apollo Loran and
Flybuddy GPS receivers. The GX55 connectors and antenna footprint are the same as the Apollo
Loran and Flybuddy GPS receivers. The GX55 is TSO-C129 Class A2 authorized for IFR en route
and terminal operation.
