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.
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
Garmin mapping units come with permanently built-in basemaps, which typically include coverage of oceans, rivers, and lakes; principal cities, smaller cities, and towns; interstates, highways, and local thoroughfares; and railroads, airports, and political boundaries. Basemaps are available in a variety of global coverage areas, depending on the user’s needs.
Industry:Telecommunications
Stationary transmitter that emits signals in all directions (also called a non-directional beacon). In DGPS, the beacon transmitter also broadcasts pseudorange correction data to nearby GPS receivers for greater accuracy.
Industry:Telecommunications
The compass direction from a position to a destination, measured to the nearest degree (also call an azimuth). In a GPS receiver, bearing usually refers to the direction to a waypoint.
Industry:Telecommunications
The frequency of an unmodulated output of a radio transmitter. The GPS L1 carrier frequency is 1575.42 MHz.
Industry:Telecommunications
The art or technique of making maps or charts. Many GPS receivers have detailed mapping—or cartography—capabilities.
Industry:Telecommunications
The difference between the indicated clock time in the GPS receiver and true universal time (or GPS satellite time).
Industry:Telecommunications
A constant difference in the time reading between two clocks, normally used to indicate a difference between two time zones.
