Important Notice

The Global Positioning System (GPS) is operated by the United States Department of Defense which is solely responsible for the accuracy, daily operation, and maintenance of the satellite constellation. System accuracy is affected by the Department of Defense's Selective Availability (SA) and the Dilution of Precision (DOP) attributed to poor satellite geometry.

This product is not intended for use as a sole source of navigation information. Exclusive reliance on this device in any navigation application is discouraged.

FCC Notice

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.

DOC Notice

This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Canadian Department of Communications.

Aviation Applications

The Precedus handheld GPS receiver is intended for use as a navigation aid. In aviation applications, the receiver should be used to complement certified navigation instruments already installed in the aircraft. This device is not intended for use as a primary or sole source of navigation information in aviation applications. Never fly the aircraft without other available means of navigation. For maximum safety and to minimize distraction in the cockpit, place the receiver in an easily visible location, within convenient view of other avionics.

This device emits a small amount of electromagnetic energy. Do not place the receiver closer than 250 mm (approx. 10") to the wet compass in the cockpit.

Due to implementation of Selective Availability by the United States Department of Defense (DoD), all GPS receivers may suffer degradation of position accuracy. The DoD has stated that 95% of the time accuracy will not be degraded more than 100 m and 99.9% of the time accuracy will not be degraded more than 300 m.

The following guidance has been issued by the FAA, Seattle Aircraft Certification Office and Seattle Aircraft Evaluation Group on December 12, 1994. It is relevant to the use of portable GPS navigation systems in aircraft:

The information contained in FAA Flight Standards Notice No. 8310.171, dated October 19, 1992, is still applicable. The use of portable GPS receivers in aircraft falls under FAR 91.21 for Portable Electronic Devices for operations conducted under FAR part 91 Operating Rules Only. It is the responsibility of the aircraft operator to ensure that the device does not interfere with other systems in the aircraft. The GPS system must not be used for primary navigation and can only be used for comparison purposes during flight(s).

Introduction to GPS Navigation

GPS Overview

The Global Positioning System (GPS) is a constellation of 24 satellites in six orbit lanes 10,898 nautical miles above the earth at an inclination angle of about 55 degrees from the equator. Each satellite orbits the earth twice in 24 hours.

The GPS was developed and the satellites launched by the U.S. Department of Defense with the original intent of supplying highly accurate position fix information for military applications. In recent years, commercial applications for the information provided by this system have steadily increased in the civilian sector. Some of the more popular civilian uses of the system include surveying and position fix data recording for civil engineering applications, and a broad range of marine, aviation, and terrestrial navigation applications.

While orbiting the earth, each GPS satellite transmits complex streams of data containing the operational status and orbital location of all the satellites in the system. The Precedus™ receives this data stream and processes the information to determine which satellites are “visible” to the receiver’s antenna. With this determination made, the receiver chooses satellites to calculate a position fix. Using information transmitted from three or more satellites, the

Illustration of three satellites orbiting Earth with ground-based communication links (no text or symbols)

GPS System Accuracy

unit can calculate latitude and longitude (usually abbreviated Lat/Lon); with four or more satellites, GPS altitude can also be calculated.

The GPS allows a high degree of position fix accuracy. The system can produce a position fix accurate to within less than one meter. Due to concern for national security, the U.S. Department of Defense introduces constant errors to the transmitted satellite data to degrade the accuracy of the system. Called Selective Availability, this practice limits GPS position fix accuracy to about 100 meters, although the relative position of the satellites to one another, their elevation above the horizon, and other factors can also affect accuracy of the position fix. Under optimal conditions, accuracy can improve to within 10 meters. GPS position fix accuracy is not affected by atmospheric conditions.

GPS altitude is based on a mathematical model of the sphere of the earth. Including intentional degradation, GPS altitude may differ from barometric altitude by several hundred feet.

Summary

Unlike navigation aids providing a position fix with data from land-based sources, the Precedus™ can provide an accurate position fix over land or sea anywhere in the world. The unit includes an extensive database of useful waypoint information and allows you to create up to 1,000 “customized” waypoints of your own. With the power of this navigation device in the cockpit, you can easily navigate with unsurpassed accuracy.

Operation Basics

Getting Started the First Time

This section explains how to get started using the Precedus. Information in this section explains how to startup the unit, check signals from the GPS satellites, enter a seed position, assign a destination waypoint, and detach your antenna.

This section shows you how to start the Precedus and check for proper operation. It is necessary to enter a seed position and the current time the first time you turn the unit on.

• Charge the battery before using the Precedus
- Power on
• Enter a seed position (your dealer may have already completed this step for you)
• Enter the current time
• Check satellite signal strength
• Enter a "GOTO" waypoint
- Begin navigating

Power Up

AMERICAS DATABASE EXP: 08/17/95 Precedus PRESS ENTER

To switch the unit on, press MENU . The startup screen and database information shows on the display for several seconds and then will go into the Navigation function.

Seed Position

The first time the Precedus is switched on, it must locate satellites in the sky to acquire signals before determining a position fix in a complex process involving lengthy mathematical operations. Without a seed position and the current time and date, this process can take 10 minutes or more to complete. Enter a Seed Position to allow the receiver to quickly locate and track available satellites.

Note

The seed position and current time only needs to be entered the first time the receiver is switched on.

This information is stored in memory and need not be entered again. If you move about three hundred miles without the Precedus turned on and tracking its position, reenter the seed position.

The unit shows the GPS signal strength screen in the Navigation function.

Checking GPS Signal Strength

While the Precedus acquires signal information from satellites, the bars representing signal strength show grey in color. This process takes place quickly. When the unit has acquired a signal and begins tracking a satellite, the bar will change to black.

The GPS signal strength screen is located in the Navigation function. Make it a habit to check this screen to make sure that the unit is properly tracking visible satellites before you fly.

In this example, the GPS Status screen shows that eight satellites are available, seven satellites are being tracked, and five signals (dark boxes) are acquired and usable for navigation. The Precedus requires signals from at least four satellites to calculate a 3D position fix (Lat/Lon and GPS altitude).

Checking Each Satellite Press the ◀ ➤ buttons to view information about the visible satellites.

ID numbers of tracked satellites (statistics are for the highlighted satellite) Signal Strength (0 - 255) 12 Satellites visible in sky from current position Number of satellites available in the system 3D Fix (including GPS altitude) being calculated GPS STATUS Signal strength of tracked satellites Tracking Status (0-8) Satellite Elevation (Vertical angle from the horizon) Satellite Azimuth (Bearing relative from North) Precision Dilution of Precision (DOP) or merit value of position fix accuracy based on current conditions: 3 is good, greater than 7 is poor Technical GPS diagnostic value. No useful information for the user.

Important!

The GPS antenna must be able to “see” each satellite it is tracking. If a satellite is “shaded” by the wing or fuselage during a turn, it may temporarily lose track of that satellite. If this happens, or if the geometry of the satellites available is poor, the unit may temporarily calculate a “2D Fix” and altitude information will not be available.

Entering a Destination Waypoint With a seed position and the current time and date set, the Precedus is ready to begin navigating a trip. Prepare for trip navigation by entering a destination waypoint.

Navigation Basics

This section explores the navigation function and describes the powerful features it contains. When you become comfortable operating the unit, you may wish to “fly” the Precedus using the built-in simulator. Follow the instructions in the Tutorial section.

About the Navigation Function

The navigation function is always active. When you use other functions, the navigation function continues to run “in the background” calculating your present position, navigating your programmed route (if active), and alerting you to events or conditions important to navigation. When you finish using other functions and return to the navigation function, the last navigation screen used is displayed.

About the Navigation Function Screens

While you navigate, the Precedus gives you information in the Navigation function screens. Screens provided are: zero to four Navigation information screens (number is selected by the user in the System Setup function), HSI Display, messages, GPS status, route waypoints, navigation information and moving map, and moving map alone. The navigation information screens are user-programmable.

The ▼ ▲ buttons “scroll” or page forward or backward through the screens. This section describes each screen.

GPS Status

The GPS Status screen contains information about signals received from visible satellites in the sky.

The GPS information screen tells you:

- The type of position fix currently calculated by the unit: 0D: no signals available

2D: the position fix is calculated based on signals from only three satellites and GPS altitude is not available

3D: the position fix is calculated based on signals from four or more satellites, and GPS altitude is available

• The total number of operational GPS satellites in orbit

- The number of satellites visible in the sky from your position and their status

- The Dilution of Precision (DOP) value for the position fix provided by the satellite constellation - a high value (6 or greater) indicates poor position reliability, while a value of 3 or less indicates good position reliability

In addition, individual satellite information is available by pressing the location follows:

• The strength of the received signal from each satellite

- The satellite azimuth and elevation from the current position

- The GPS receiver's current track status for each visible satellite

Messages The Precedus helps you navigate by informing you of important events or conditions while you fly. When an important event or condition occurs, an alert message shows on the display to inform you. When you see one of these alerts on the display, follow the instruction shown to clear it. Clearing the alert removes it from the display. The screen shown before the alert appeared returns to the display. Alerts may show on the display anytime the unit is operating.

Press the ▼ button to move the arrow cursor down the list to select a destination. Press INFO to view waypoint information. Press GO TO NRST and then the ENTER button to assign your chosen waypoint as a destination. The display returns to the navigation function automatically.

You can also return to the navigation function without assigning a new destination waypoint from the list by pressing the button.

Important

You can control the types of waypoints that show on the display as the result of a search for nearest waypoints. The “MAP SETUP” menu function allows you to choose whether or not to display airports, VORs, NDBs, and intersections as searched waypoints and on the moving map screens. Before you fly, make sure to check this option and confirm that the waypoint types you wish to show will appear on the display after a search and while using the moving map screens.

Creating User Waypoints

The Precedus allows you to create up to 1,000 of your own waypoints, each with a 6-character name you choose. As you navigate, you may wish to create waypoints at locations that are important to you, or waypoints to which you plan to return. You can use your present position or enter either lat/lon coordinates or radial and distance position relative to another waypoint for the waypoint's location.

Note

The Precedus automatically sets magnetic variation to 0 degrees when you fly above 70 degrees north or south latitude. It is not necessary to disable automatic magnetic variation as you travel north or south to high latitude regions.

Press the ▼ button to highlight the Map Datum Type and then press ◀ or ▶ to select the desired Map Datum.

The following list shows the GPS map datums contained within the Precedus. Each map datum represents a mathematical model of the earth used for the purpose of establishing precision in charting various areas of the earth. Since each datum relies on a different mathematical model, inconsistencies exist in defining the location of charted points between datums. For this reason, it is important to verify that you have selected the correct map datum for the area where you navigate and the chart you use.

Note

WGS-1984 is the default datum until you change it.

Waypoint Database

Database Structure

The Precedus provides an extensive built-in database of waypoint information to aid the navigator. Waypoints in the database are divided into 5 categories. This structure allows you to easily select a waypoint as a destination, search for waypoint information, search for nearest waypoints, or display waypoints on moving map screens.

The waypoint types are:

• Airports (ARPTs)
• Non-directional beacons (NDBs)
• Very high frequency omniranges (VORs)
• Enroute intersections (INTs)
• User created (USERs)

Available Waypoint Information

The following information is available for each waypoint type. Use the waypoint INFO function to get this information as the Introduction describes in “Waypoint Information.”

ARPT Waypoint Information

• Bearing and distance from present position
- Airport type
- Airport elevation
• Fuel availability by type
• Runway length(s) and surface type
• Radio communication frequencies (an asterisk at the frequency indicates part-time availability)
• Lat/Lon coordinates
• Navigation beacon light

Tutorial

This section gives a tutorial on using the built-in simulator to practice “flying” the Precedus. Use this tutorial at your own pace to become familiar with using the unit.

During the tutorial, you will use many of the Precedus's features as you would during an actual trip. All operating functions are available while you use the simulator. Each will work the same way when you actually navigate later.

Get comfortable and take some time to follow the instructions in this section to “fly” with the Precedus. As you navigate with the simulator, feel free to experiment with the features as much as you like. The instructions here should serve only as a general guide. The goal of this tutorial is to help you become comfortable using the Precedus.

When you finish using the simulator, switch the unit off. The next time you switch it on, simulator mode will be automatically canceled and the unit will be set to aviation mode for actual navigation.

Preparing for the Trip

Before you navigate a trip, determine whether you will fly direct to a waypoint, or navigate a route of several waypoints. This tutorial presents instructions to set up either kind of trip. It may be helpful to first navigate direct to a destination before setting up a route to travel.

Originating the Trip

The Precedus's simulator uses your present position as the point of origin for the trip unless you have already used the unit to navigate a route. If this is the case, refer to the tutorial section entitled “Navigating a Route” later in this section, or deactivate your route and continue. These exercises assume your present position is the point of origin for the trip.

Scroll through the navigation screens to check your progress and decreasing range to the destination. When you are within several miles of the destination, adjust your ground speed to slow your rate of travel to approximately 30 knots. See “Setting the Ground Speed” earlier in this tutorial. Use the moving map screen to view your arrival at the destination. Set the map scale to auto zoom. At this slower rate of travel, you can clearly see the approaching destination. As you approach, you can see the runway configuration.

Note

The simulator will not “land,” but shows a “fly-by” and continues travel at the current heading and ground speed until you enter another destination. When you do this, the heading changes and the unit navigates to the new destination. You can stop travel at any time by adjusting ground speed to 0.

Setting Up a Route

The Precedus can store up to 20 routes or multiple leg trips of up to 30 waypoints each. After you create a route, you can edit it to add or change waypoints anytime. You can also delete waypoints from existing routes. See pages 29-36 in the Navigation Basics section for Route editing details. You can navigate any route you choose, but only one route can be active at any time.

Selective Availability (SA): The degradation of accuracy of GPS position fix data by the United States Department of Defense for civilian use.

Statute Mile: A distance measurement equal to 5,280 feet or 0.87 of a nautical mile.

T Three-dimensional (3D) Position Fix: A position fix defined by latitude, longitude, and altitude.

TOT: Total Outside Temperature. Also called indicated air temperature, this is the total temperature of the outside air temperature (TRU) and the heating effect of the aircraft moving through the air. The heating effect is usually negligible for most piston aircraft.

Track (TRK): The imaginary line that the flight path of an airplane makes over the earth.

TRU: True outside air temperature.

True North: Geographic north, at the earth's north pole.

Tower (TWR): Airport tower communication frequency

U UNICOM: The radio frequencies assigned to aeronautical advisory stations for communication with aircraft. Unicoms

may provide such airport information as active runway, wind direction and velocity and other conditions of importance to pilots.

Universal Coordinated Time (UTC): Greenwich Mean Time, or the time at the Prime Meridian in Greenwich, England. Also referred to as Zulu time.

UTC Differential: The difference in time between that at the present position and UTC.

Universal Transverse Mercator Map Projection System (UTM): Also known as Military Grid Coordinates, the UTM grid consists of 60 north-south/east-west zones, each six degrees wide in longitude.

V Very High Frequency Omnirange (VOR): A navigational aid that transmits signals such that a receiver can indicate its current radial or bearing from the transmitter.

W Waypoint: A navigation fix used in area navigation and defined by latitude and longitude coordinates.

Display Care and Cleaning

Your new Precedus GPS has a hard coating that has been applied to the display screen. Despite this coating, care must be taken when cleaning the display screen. To remove stains, smudges, fingerprints, and so forth, we recommend these cleaning methods (if the first method fails to remove the problem, try the next method):

• Wipe with a clean, dry, non-abrasive fabric (for example, cotton or Handi-wipes). Do NOT use paper products, such as paper towels or facial tissues.
• Blow on the area to condense moisture on the display and then wipe the area with the clean fabric
• Moisten a clean fabric with a small amount of water and wipe the display area
• Apply a small amount of glass cleaner (without ammonia) to the fabric and wipe the area
• Apply a small amount of isopropyl alcohol and wipe the area (this is the last resort)

Note

Use a clean fabric with each cleaning method to avoid other contaminants. Do not use paper products.

Battery Care

Charging the Battery The Precedus comes with a high quality rechargeable NiCd battery. This battery is not charged and needs to be charged two to three times to reach full capacity before its first use. A built-in battery charger will charge the battery when the unit is connected to external power.

Charge the battery by connecting the Precedus to external power using either the AC adapter or the cigarette plug. Leave the unit plugged in for a minimum of eight hours. The Precedus will automatically stop charging and maintain the full charge.

Battery Memory The battery may lose some of its capacity if the battery is only partially discharged and then charged again. This loss of capacity is called the memory effect and can be reversed by discharging the battery completely before charging it again. Leave the Precedus on until the battery is completely discharged and then charge the battery to recondition it. A special battery charger/reconditioner available for the Precedus will accomplish this automatically.

Desktop Charger A desktop battery charger/reconditioner is available for the Precedus and will quick-charge the battery in approximately one hour. The desktop charger has a built-in reconditioner that will remove the memory effect from your battery.
