Government and is subject to change in accordance with the Department of Defense civil GPS user policy and the Federal Radionavigation Plan. USE CAUTION Accuracy can be affected by poor satellite geometry. [. . . ] Use the CURSOR KEY to select an option and press ENTER.

Selecting Map Orientation When navigating on the map, there are two methods of orienting the map and the boat icon. When Map Orientation is set to North Up, the boat icon rotates according to its COG direction, with respect to north; the map does not rotate. North Up Track Up When Map Orientation is set to Track-Up, the boat icon always points up while the map rotates so the top of the screen is always the COG direction. The map rotates every time COG changes more than the specified number of degrees set. Press the Aux softkey, highlight Navigation Setup using the CURSOR KEY, press ENTER, highlight Map Orientation using the CURSOR KEY, and press ENTER. Use the CURSOR KEY to highlight North Up or Track Up and press ENTER to accept. If Track Up is selected, the resolution of rotation must be entered (the default is 10°). Default setting: North Up Direction related information such as COG, BRG, CTS and Set can be referenced to True North or Magnetic North (Auto Mag. ).

Use the 42 Magellan NAV 6500/NAV 6510 Setting Projected Course and press ENTER. [. . . ] This random error, known as Selective Availability (SA) is not due to receiver error and is not significant enough to affect navigation for most purposes (See DGPS in appendix). Geometric Quality (HDOP) GOTO Measures the probable accuracy of a position fix, based on the position of the satellites relative to each other. A single leg route with the present position being the start of the route and a defined waypoint as the destination. 99 Magellan NAV 6500/NAV 6510 Heading The direction in which the receiver is moving, track or ground course, (due to wind, current, and so forth), and may also be different from the course. The angular distance north or south of the equator measured by lines encircling the earth parallel to the equator in degrees from 0° to 90°. [. . . ]
