Usage Notice
Please read before you start to use the GPS receiver:
Ø GPS(Global Position System) is found and operated by US Department of defense. The
Organization is responsible for accuracy and maintenance of the system with full authority. Any
change that is made by the organization will affect accuracy and function of GPS.
Ø For your driving security, we strongly suggest that you do not operate the device during driving.
Ø When satellite is navigating, if you are inside a building, tunnel or near huge blocks, it will affect
GPS satellite signal receiving. At this time, this device probably dose not have positioning
capability.
Ø If you have a speed alarm in your car, the signal receiving of this device will be interfered. If this
situation happens, pleas e stop using your speed alarm.
Ø The receiver operating temperature is located between -10℃~70℃.For safety and lifetime of
Li-ion battery usage, do not place this device over two hours with overheated environment.

1. Introduction
1.1 Introduction
G-Mouse MR is a total solution GPS receiver (G-MR instead below), designed based on most
high sensitivity MediaTek kernel architecture. 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
dual-channel through RS-232 or TTL and saves critical satellite data by built– in backup memory. With
low power consumption, the G-Mouse tracks up to 32 satellites at a time, re-acquires satellite signals in
1 sec and updates position data every second. 4 power-saving mode allows the unit operates with ultra
low power request.
1.2 Features
G-MR provides a host of features that make it easy for integration and use.
1. Use the most advantage GPS module (MediaTek), the module got high performance CPU
inside(ARM CPU), allow users to design different applications, store in the module, to provide the
most economic solution for anybody.
2. High performance receiver tracks up to 32 satellites while providing first fast fix and low power
consumption.
3. Compact design ideal for applications with minimal space.
4. A rechargeable battery sustains internal clock and memory. The battery is recharged during normal
operation.
5. Auto switch-able power saving mode 1~4, reduce your power exhaust.
6. User initialization is not required.
7. Dual communication channels and user selectable baud rates allow maximum interface capability
and flexibility.
8. Optional communication levels, RS -232 and TTL meet ordinary application and new fashions of
connecting PDA with TTL or RS-232 output.
9. FLASH based program memory: New software revisions upgradeable through serial interface.
10. LED display status: The LED provides users visible positioning status. LED "Blinking" when
power connected and "On" when G-Mouse got positioned.
11. Industry level water proof design for all weather.

2. Operational Characteristics
2.1 Initialization Setup
After the initial self-test is complete, the G-MR will begin the process of satellite acquisition and
tracking. The acquisition process is fully automatic and, under normal circumstances, will take
approximately 37 seconds to achieve a position fix (36 seconds if ephemeris data is know). After a
position fix has been calculated, valid position and time information will be transmitted over the output
channel(s).
The G-MR utilizes initial data such as last stored position, data and time as well as satellite orbital
data to achieve maximum acquisition performance. If significant inaccuracy e xists in the initial data, or
if the orbital data is obsolete, it may take a long time to achieve a navigation solution. The G-MR
Auto-locate feature is capable of automatically determining a navigation solution without intervention
from the host system. However, acquisition performance can be improved if the host system initialized
the G-mouse following the occurrence of one or more of the following events:
