    Welcome from the magellan crew. With the purchase of a magellan gps satellite receiver, you have joined the thousands of people who enjoy using gps in their professional and recre- ational activities. Since we introduced our first product more than five years ago, magellan has established a reputati...

    Use good judgement this product is an excellent navigation aid, but does not replace the need for careful orienteering and good judgement. Never rely solely an one device for navigating. Use care the global positioning system (gps) is operated by the u.S. Government, which is solely responsible for ...

    This is much like de- scribing a position in a city by the street inter- section, but "fifth and main" can describe more than one location, since these are com- monly used designa- tions. Lat/lon uses numbers and hemi- sphere to describe each position in a unique way. Using lat/lon co- ordinates, no...

    "camp." as you walk to your skiff at the dock, the receiver continues to obtain position fixes; these are "updates" to the first fix obtained. Once at the dock, you save the current position fix as waypoint "dock." instead of travelling directly across the lake to the inlet on the other side, you ma...

    The first thing you have to do is to return to your skiff, which you do by getting a current position fix, then setting a direct-to course. A direct-to course is a straight line from your current position to the waypoint you select. Here, the direct-to course is to waypoint "in- let". The direct-to ...

    Setting a route with stored waypoints to navigate safely from the inlet to the dock, you set a route from inlet to buoy, then to dock. A route is required to help you avoid the shallow area or any rocks that you may not see when visibility is poor. A route is a planned course from one place to anoth...

    The magellan gps receiver displays xte graphically on a course deviation indicator, or cdi. The cdi displays the courseline at the center of a scale, and your current position relative to the courseline is shown as a symbol. When you are to the left of the courseline, the symbol is to the left of th...

    A utm position is described by three elements; the zone it is in, the easting, and the northing. Eastings and northings measure how far into a zone a position is in meters. Eastings are an east/west measurement, and correspond roughly to longitude. Northings are a north/south measurement, and corre-...

    What is gps? Gps is a constellation of navigation satellites that orbit the earth. The precise time and position information transmitted by these satellites is used by a gps receiver to triangulate a position fix. The system is expected to be completed during 1994, and will provide continuous, 24-ho...
