1. Introduction
1.1. Overview
Modulestek GPS module MG-ST01 is a high sensitivity ultra low power
consumption cost efficient, compact size; plug & play GPS module board designed for a
broad spectrum of OEM system applications. This product is based on the SkyTraq GPS
technology and it will track up to 44 satellites at a time while providing fast
time-to-first-fix. Its far reaching capability meets the sensitivity & accuracy
requirements of car navigation as well as other location-based applications, such as AVL
system. Handheld navigator, PDAs, Wrist Watches, Personal Locators, Toll collection,
Fleet Management, pocket PC, or any battery operated navigation system.
The MG-ST01 design utilizes the latest surface mount technology and high level
circuit integration to achieve superior performance while minimizing dimension and
power consumption. This hardware capability combined with software intelligence
makes the board easy to be integrated and used in all kinds of navigation applications or
products. The module communicates with application system via RS232 (TTL level)
with NMEA0183 protocol.
