Introduction

GPS Overview

What is GPS?

GPS (Global Positioning System) is a satellite-based navigation system developed by the U. S. Department of Defense to provide a consistent, accurate method of simplifying navigation. Originally designed for military applications, it also provides commercial and recreational users with 24-hour, worldwide navigation coverage with accuracy to 15 meters (49 feet).

How Does GPS Work?

GPS navigation uses satellite ranging to determine your position in relation to a set of satellites orbiting the earth. The GPS constellation is made up of 24 satellites, which continuously send radio signals containing precise position and time information for each satellite back to earth.

By knowing the position of any 3 or 4 of these satellites and calculating various time differences between the transmitted signals, your GPS receiver can determine its present position anywhere on earth. And once you’re under way, your GPS continuously updates your position and provides speed and track information.

What are the Advantages of GPS Navigation?

The GPS system provides pilots with a highly efficient, reliable system for pointto-point navigation without total reliance on traditional ground-based navigation aids. GPS takes navigation to a higher level by providing accurate position and course information, anywhere in the world, regardless of the weather or your proximity to traditional navaids. The accuracy and coverage of GPS navigation can help make your ﬂying safer, smarter and more efficient wherever you may travel.

Getting

Started

Basic

Deﬁnitions

The GPS 90 is a powerful navigation tool that can guide you anywhere in

the world. To better understand its operation and capabilities, it may be helpful to review the basic terms and concepts brieﬂy explained below.

Navigation is the process of traveling from one place to another and knowing

where you are in relation to your desired course.

Position is an exact, unique location based on a geographic coordinate system.

Most aviation navigation is based on the latitude/longitude coordinate system.

Meridians of longitude are a set of imaginary circles around the earth that pass

through the north and south poles. Longitude describes position in terms of how

many degrees it is east or west of the Prime Meridian (0º longitude).

Parallels of latitude are another set of imaginary circles that are perpendicular

to the earth’s polar axis. Latitude describes position in terms of how many

degrees it is north or south of the equator (0º latitude).

A waypoint marks an exact position ﬁx so it can be recalled for future use. The

GPS 90 lets you mark waypoints electronically, without physical landmarks.

Bearing is a compass direction to a particular destination (waypoint) from your

present position.

Track is a compass direction representing your course over ground.

Getting Started

Keypad Usage

The GPS 90’s two-speed thumbkey allows convenient, one-handed entry of information. Press on a particular arrow key once to scroll through data options slowly, press and hold an arrow key for faster scrolling.

• Use the up and down arrow keys to select alphanumerical characters and menu choices and to move the ﬁeld highlight from ﬁeld to ﬁeld.

• Use the left and right arrow keys to move the selected character ﬁeld and to move the ﬁeld highlight from ﬁeld to ﬁeld.

The GOTO/NRST key quickly sets a direct course to a selected destination. Pressing GOTO twice activates the NRST mode.

The POWER key turns the unit on and off and activates screen backlighting. To turn the unit off, press and hold the POWER key for 3 seconds.

The QUIT key returns you to a previous page, or clears data entry, restoring a data ﬁeld’s previous value.

The PAGE key scrolls through main data pages in sequence and returns the display from a submenu page to the previous page viewed. It also displays the message screen when a message alert appears.

The WPT key provides access to the GPS 90’s internal database of airports, VORs and other waypoints and the AutoStore function.

The ENTER key conﬁrms data entry and on-screen responses. The ENTER key also activates highlighted ﬁelds to allow data entry.

The GARMIN GPS 90 is a powerful navigation tool that o ffers pilots a host of advanced features that help make flying safer and more efficient. The Ta k e o ff Tour is designed to quickly guide you through basic features and functions of the GPS 90 using a simulated trip.

Once you’ve completed the tour and become familiar with the main pages and features of the unit, refer to the reference section for complete instructions on installation, initialization and performing speciﬁc tasks and functions.

The takeoff tour assumes you have not changed any of the default settings for the unit. If you have changed any settings, the descriptions and pictures used may not match your configuration (see the troubleshooting sec tion in Appendix D to reset your unit to default settings).

Now let’s return to the Map page to ﬁnish the tour. If

you’re not already on the Map page:

1. Press Prepeatedly until the Map page appears.

You may have noticed that a s we make our way towards the destination airport, the map scale has automatically zoomed in to provide a closer look of the airp o r t. What you’re actu all y s ee ing is the GPS 90’s AutoZoom feature. Whenever you select a GOTO destination, the Map Page will default to the 80 nm setting, and gradually zoom down the map scale to the 1 nm setting.

The map scale will zoom to the next lowest setting (i.e., from 80 nm to 40 nm) whenever the map can fit both your present position and your destination on the screen. If you manually zoom in the map scale before this point, the AutoZoom feature will resume once it catches up to the map scale you have selected (down to 2 nm). If the map is manually zoomed out beyond the AutoZoom scale, the Autozoom will be cancelled, and the GPS 90 will assume you want to stay at the scale you have manually selected. For more information on the AutoZoom feature, please see page 41.

By now, our plane should be approaching 3R9, the destination airport. As the map zooms in to the 10 nm range, you’ll be able to see the runway appear right on the screen. Let’s move back to the Navigation page and ﬁnish up our tour:
