1. Introduction
1.1 Overview
The ZYM-GM7033 Smart GNSS Receiver is a total solution GNSS
receiver, designed based on MediaTek.Inc SOC MT3333AV . This
positioning application meets strict needs such as car navigation, mapping,
surveying,security, agriculture and so on. Only clear view of sky and
certain power supply are necessary to the unit. It communicates with
other electronic utilities via compatible RS232 and saves critical satellite
data by built–in backup memory. With low power consumption, the
GM7033 tracks up to 99 satellites at a time, re-acquires satellite signals in
100 ms and updates position data every second.
Trickle-Power allows the unit operates a fraction of the time and
Push-to-Fix permits user to have a quick position fix even though the
receiver usually stays off.
1.2. Features
G-Mouse provides a host of features that make it easy for integration and
use.
1. Use the advanced GNSS module, the module got high performance
DSP core(32bit ARM RISC), allow users to design different applications,
store in the module, to provide the most economic solution for anybody.
2. High performance tracks up to 99 satellites.
3. High sensitivity (-165 dBm) for indoor fixes. The GM7033 GNSS
module can acquire in only seconds even at low signal levels. As part of
GM7033’s patented multi-mode GNSS, the GM7033 GNSS module can
track signal levels as low as -165 dBm. The GM7033 supports real-time
navigation in urban canyons as well as high sensitivity acquisition needed
for indoor environments.
4. Differential capability utilizes real-time RTCM corrections producing
