Garmin designs, develops, manufactures and markets a diverse family of hand-held, portable and fixed-mount GPS-enabled products and other navigation, communications and information products for the general aviation and consumer markets.
An instrument for determining elevation, especially an aneroid barometer used in aircraft that senses pressure changes accompanying changes in altitude. The Garmin® eTrex® Vista and Summit models contain a basic GPS with a built-in barometric altimeter.
Industry:Telecommunications
A very precise clock that operates using the elements cesium or rubidium. A cesium clock has an error of one second per million years. GPS satellites contain multiple cesium and rubidium clocks.
Industry:Telecommunications
This is a proprietary feature of Garmin GPS receivers. A Garmin unit displays the "AutoLocate" status when it is looking for and collecting data from satellites that were visible at its last known or initialized position (almanac data), but it has not collected enough data to calculate a position fix.
Industry:Telecommunications
The horizontal direction from one point on the earth to another, measured clockwise in degrees (0-360) from a north or south reference line. An azimuth is also called a bearing.
Industry:Telecommunications
The art or technique of making maps or charts. Many GPS receivers have detailed mapping—or cartography—capabilities.
Industry:Telecommunications
A set of numbers that describes your location on or above the earth. Coordinates are typically based on latitude/longitude lines of reference or a global/regional grid projection (e.g., UTM, MGRS, Maidenhead).
Industry:Telecommunications
A pattern of regularly spaced horizontal and vertical lines forming square zones on a map used as a reference for establishing points. Grid examples are UTM, MGRS, and Maidenhead.
Industry:Telecommunications
A unit of length used in sea and air navigation, based on the length of one minute of arc of a great circle, especially an international and U.S. unit equal to 1,852 meters (about 6,076 feet).
Industry:Telecommunications
The act of determining the course or heading of movement. This movement could be for a plane, ship, automobile, person on foot, or any other similar means.
Industry:Telecommunications
The message transmitted by each GPS satellite containing system time, clock correction parameters, ionospheric delay model parameters, and the satellite’s ephemeris data and health. The information is used to process GPS signals to give the user time, position, and velocity. Also known as the data message.
