Datasheet of GPS smart antenna module, LS20030~3
1 Introduction
LS20030~3 series products are complete GPS smart antenna receivers, including an
embedded antenna and GPS receiver circuits, designed for a broad spectrum of OEM system
applications. The product is based on the proven technology found in LOCOSYS 66 channel GPS
SMD type receivers MC-1513 that use MediaTek chip solution. The GPS smart antenna will acquire
up to 66 satellites at a time while providing fast time-to-first-fix, one-second navigation update and
low power consumption. It can provide you with superior sensitivity and performance even in urban canyon
and dense foliage environment. Its far-reaching capability meets the sensitivity requirements of car
navigation as well as other location-based applications.
This module supports hybrid ephemeris prediction to achieve faster cold start. One is self-generated
ephemeris prediction that is no need of both network assistance and host CPU’s intervention. This is valid for
up to 3 days and updates automatically from time to time when GPS module is powered on and satellites are
available. The other is server-generated ephemeris prediction that gets from an internet server. This is valid for
up to 14 days. Both ephemeris predictions are stored in the on-board flash memory and perform a cold start
time less than 15 seconds.
