To better understand its operation and capabilities, it may be helpful to review the basic terms and concepts briefly explained below. Other navigation and GPS definitions used in the manual are defined in the appropriate reference sections of the manual. Almanac Data Satellite constellation information (including location and health of satellites) that is transmitted to your receiver from every GPS satellite. Almanac data must be acquired before GPS navigation can begin. Bearing (BRG) The compass direction from your position to a destination. Course Made Good (CMG) The bearing from the "active from" position (your starting point) to your present position. Crosstrack Error (XTK) The distance you are off a desired course in either direction. Desired Track (DTK) The compass course between the "from" and "to" waypoints. Differential GPS (DGPS) An extension of the GPS system that uses land-based radio beacons to transmit position corrections to GPS receivers. Estimated Time of Arrival (ETA) The time of day of your arrival at a destination. Estimated Time Enroute (ETE) The time left to your destination at your present speed. 2 INTRODUCTION Glossary Grid Coordinate system that projects the earth on a flat surface, using square zones for position measurements. UTM/UPS and Maidenhead formats are grid systems. Ground Speed (SPD) The velocity you are traveling relative to a ground position. Latitude The north/south measurement of position perpendicular to the earth's polar axis. Longitude An east/west measurement of position in relation to the Prime Meridian, an imaginary circle that passes through the north and south poles. Navigation The process of traveling from one place to another and knowing where you are in relation to your desired course. Position An exact, unique location based on a geographic coordinate system. Track (TRK) The direction of movement relative to a ground position. Universal Transverse Mercator (UTM) A grid coordinate system that projects global sections onto a flat surface to measure position in specific zones. Velocity Made Good (VMG) The speed you are traveling in the direction of the destination. Waypoint A specific location saved in the receiver's memory. 3 INTRODUCTION Battery Installation Battery Installation The GPS 12 operates on 4 AA batteries, which are installed at the base of the unit. These batteries provide up to 24 hours of use. To install the batteries: 1. Remove the battery cover by turning the thumb loop at the bottom of the unit 1/4 turn counterclockwise. 2. Insert the batteries into position. The battery pole you can still see should match the symbol (+ or ­) marked on the case. 3. Replace and secure the battery cover by turning the thumb loop 1/4 turn clockwise. Battery life varies due to a variety of factors, including temperature and backlighting. You may find that lithium batteries provide longer life in colder conditions. 4 INTRODUCTION Keypad Usage & Data Entry B P M G E Q U D LR Turns the unit on and off and activates screen backlighting.
