LS20030 / 31 / 32 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.
