B. Put G-Mouse MR in a appropriate place to receive the best GPS satellite signal.
C. Turn on your equipment (or switch the handhold device on)
D. Your G-Mouse MR will start to provide you GPS satellite positioning function.
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.
