The radio frequencies that extend from 390 MHz to 1550 MHz. The GPS carrier frequencies are in the L band (1227.6 MHz and 1575.42 MHz).

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, Mai [..]

The Global Orbiting Navigational Satellite System; the Russian counterpart to the United States’ GPS system.

A method of determining the location of an unknown point, as in GPS navigation, by using the laws of plane trigonometry.

See Time To First Fix.

See Universal Transverse Mercator.

A two-dimensional GPS position fix that includes only horizontal coordinates (no GPS elevation). It requires a minimum of three visible satellites.

A three-dimensional GPS position fix that includes horizontal coordinates, plus elevation. It requires a minimum of four visible satellites.

A measure of how close an estimate of a GPS position is to the true location.

The time it takes a GPS receiver to acquire satellite signals and determine the initial position.
