When all GPS satellites have been deployed, 3D coverage with goodgeometry will be available 24 hours a day worldwide. Until then, there maybe periods of time when only 2D coverage is available with occasionaloutages in coverage.A.3 GPS RECEIVER DESIGNSUntil now, most GPS receiver designs could be categorized as one of threetypes:· Continuous Receiverstypically consist of five or more channels witheach channel dedicated to the tracking of one satellite. Receivers withthis design provide the highest performance but are also large,expensive, and consume more power. A high dynamics vehicle suchas a fighter aircraft typically requires a continuous receiver.· Multiplex Receivers typically consist of a single channel whichrapidly sequences through five satellites at a four millisecond rate.Receivers with this design provide high update rates but suffer fromdegraded signal tracking capability. For example, a multiplex receivermay not reliably track satellites at low elevation angles.· Sequential Receivers typically consist of one or two channels whichsequence through multiple satellites at a rate much slower than thatof the multiplex receivers. Receivers with this design provide goodsignal tracking sensitivity at low cost, but lack high update rates ofcontinuous receivers.GARMIN’s MultiTracTM design represents a major breakthrough in GPSreceiver technology. Using this proprietary technology, the GPS 100provides high update rates and tracking capability similar to continuousreceivers, but consumes far less power and space. This design can handleany navigation situation from the palm of your hand to the cockpit of a fastpersonal jet.In addition to MultiTrac TM , the GPS 100 incorporates the latest innovationsin software design. As a result, this feature packed Personal NavigatorTM isextremely easy to use. The unit tracks all visible satellites and provides theuser with continuous navigation information. Satellite transitions, datacollection, and acquisition of newly launched satellites are all automaticallyhandled by its built-in intelligence.A-2
