1. Introduction
G66 BT GPS Receiver is a total solution of GPS receiver with MediaTek 51 channel
all-in-view tracking technology. GPS antenna, BT transmit/receive system are included. It is
designed on the most advantage MediaTek Chip Solution, got the full-function, and RoHS
compliant, industry-level locating capacity and low prices.
You can use this BT GPS Receiver as vehicles navigator, security system, geographic
measurement, investigations or agriculture purpose. G66 BT GPS Receiver operation
requirement is a proper power supply and the open sky-view. This BT GPS Receiver can
communicate with other electronic devices by BT interface. Built-In Flash Memory can save
satellite information and do almanac refresh periodically. This will shorten Time To First Fix
(TTFF) effectively.
The BT GPS Receiver is designed as an ultra low power consumption device, and high
position accuracy. It will update the satellite position 5 pulse per second. This BT GPS
Receiver auto-locating feature is capable of automatically determining a navigation solution
without intervention. However, acquisition performance could be interfered and do cold
start if the receiver were initialized with occurrence of the following events：
1) First in use
2) The GPS receiver is not in use for more than 3 months or transportation over
distances further than 500 kilometers.
3) Failure of the internal memory battery without system standby power.
4) While execute “Reset” function.
2. Features and Functions
1.) Superior Urban Canyon Performance
With 51 channel all-in-view tracking sensitivity –158dBm
2.) Act as WARM/HOT start with high capacity Li-ion battery
Back-up power circuit design will keep flash memory and RTC clocking always.
Shorten TTFF effectively
3.) Automatically almanac/ ephemeris update in flash memory
Programmable flash utility to do refresh on satellite orbit data information
4.) Smart power management solution.
GPS Device will automatically shutdown in case of BT connecting signal failure detected
and time over default setting value.
5.) Compatible with BT Serial Port Profile (SPP) completely.
6.) Easy to combine with the vehicle, voyage navigation, vehicle management, AVL,
personal navigation, tracking system and map applications.
