Bluetooth GPS Receiver | User Manual

1. Introduction

Just Mobile® BluCard BT GPS Receiver is a total solution of GPS receiver with
MediaTek 51 channel all-in-view tracking technology. GPS antenna, Bluetooth
transmit/ receive system are included. It is designed on the most advantage
MediaTek Single Chip Solution (MT3318), got the full-function, RoHS compliant,
industry-level locating capability and most cost-effective.

You can use this Bluetooth GPS Receiver as vehicles navigator, security system,
geographic measurement, investigations or agriculture purpose. Its operation
requirement is a proper power supply and the open sky-view. This Bluetooth GPS
Receiver can communicate with other electronic devices by Bluetooth interface.
Built-In Flash Memory can save satellite information and do almanac refresh
periodically. This will shorten Time To First Fix (TTFF) effectively.

Just Mobile® BluCard 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. The 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 Bluetooth connecting signal

failure detected and time over default setting value.

5.) Compatible with Bluetooth Serial Port Profile (SPP) completely.

6.) Easy to combine with the vehicle, voyage navigation, vehicle management,

AVL, personal navigation, tracking system and map applications.
