CHAPTER 1 INTRODUCING THE GARMIN GPS 100 1.1 GPS 100 CAPABILITIES The GPS 100 provides a host of powerful capabilities which were previously unavailable or found only in much larger and more expensive systems: · Performance: State-of-the-art MultiTrac TM receiver tracks up to eight satellites while providing high receiver sensitivity, fast first f[...]

· Multi-purpose Alarms: Dual alarm clocks and timers allow the GPS 100 to watch the clock for you. Arrival, anchor drag, CDI, and hazard alerts help you safely navigate your craft. · Offset navigation: The offset navigation feature allows you to traverse your route a fixed distance left or right from a defined course. · Interfaces: Interface wit[...]

In order to track GPS satellites, the unit must be situated with the antenna pointed straight up and should not be blocked by objects or people (signal reception through thin fabric such as canvas may be adequate but degraded). A wrist strap is provided to prevent accidental dropping of your GPS 100. (Connect the wrist strap to the eyelet on the ba[...]

A Magnetic Mount Antenna KIt is available for temporary attachment of the GPS 100 antenna to a metalic surface. This kit includes a remote weather- proof antenna and 10 feet of low-loss antenna cable. Personal Computer Kit: A Personal Computer Kit is available for real-time track plotting/map generation and downloading of almanac, waypoints, and ro[...]

Normal mode offers continuous position updates as if you were using an external power source. The GPS 100 will typically operate 8 hours on a single pack of alkaline batteries, or 5 hours using the rechargeable battery pack. Battery Saver mode, suitable for most applications, offers navigation updates that adapt to your needs while extending batter[...]

You will create a waypoint by entering its position directly, you will create a waypoint by entering an offset from a reference (existing) waypoint, and finally, you will create a waypoint by entering an offset from your present position. Create waypoint KYW[...]

· Enter the latitude of Key West, Florida (N24°34.03) by pressing 2, 4, 3, 4, 0, 3. Press the ENT key when you are finished. The cursor will automatically move over longitude as illustrated below. · Enter the longitude of Key West, Florida (W081°46.15) by pressing 0, 8, 1, 4, 6, 1, 5. Press the ENT key when you are finished. Move the cursor ove[...]

· Enter KYWST in the reference field. After doing so, the latitude and longitude will automatically fill in with the position of KYWST and the cursor will move over bearing as illustrated below. · Enter the bearing from Key West to the Dry Tortugas which is 277 degrees. After doing so, the cursor will move over distance as illustrated below. · E[...]

· Move the cursor over “OK?” and press ENT. You have just created a waypoint right at your present position named FTMYR. Now that the sample waypoints are created, we will create the sample route using these waypoints. Create the sample route... · Press the RTE key until the Route Catalog Page is displayed as illustrated below. · Press the r[...]

· Enter DRYTG as the second waypoint of the route. · Enter KYWST as the third waypoint of the route. This is the waypoint where our voyage will end. If you haven’t already guessed, you have just created a route that will take you from Fort Myers to the Dry Tortugas and on to Key West. Activate the sample route... · Move the cursor over “ACT?[...]

· Press 0, 1, 5, followed by the ENT key, to indicate 15 knots (You may enter any speed you wish). The simulation velocity is now set. The page will indicate velocity, bearing, range, CDI and ETE information. · You may use the CLR key while the cursor is over any field proceeded by “>” to select a different display option. Try placing the [...]

you are on your way to Key West! · If you have not customized your unit, this may be a good time to review Chapter 11 for information concerning custom settings. Doing so will help you understand what each setting will do. · If you wish to stop the simulation, simply turn the GPS 100 off. We recommend that you delete the routes (see Section 7.5) [...]

APPENDIX A GPS — HOW DOES IT WORK? A.1 GPS OVERVIEW The Global Positioning System (GPS) is a satellite based navigation system that provides precise position, velocity, and time information. This navigation system may be used in marine, aviation, and land vehicles, as well as by hunters, hikers, and military forces. The heart of the Global Positi[...]

When all GPS satellites have been deployed, 3D coverage with good geometry will be available 24 hours a day worldwide. Until then, there may be periods of time when only 2D coverage is available with occasional outages in coverage. A.3 GPS RECEIVER DESIGNS Until now, most GPS receiver designs could be categorized as one of three types: · Continuou[...]

APPENDIX C LOCAL TIME TO UTC TIME CONVERSION To find UTC time from your local time, add the adjustment for your longitude zone given below. (If you are in a daylight savings time zone, subtract one hour from the adjustment.) For example, if you are at longitude W081°00.00' and your local time is 11:00 standard time, add 5 hours to obtain UTC [...]
