Abstract

A Bluetooth GPS receiver with an electronic compass is provided. The GPS receiver contains a main electronic member, a front frame member, a back frame member, a battery module, a front cover, and a battery cover. The main electronic member has a satellite antenna in the front. Around the circumference of the satellite antenna, a number of dual-color LEDs are configured. Based on the Earth'"'"'s magnetic field, the LEDs corresponding to the north and south poles are lit in appropriate colors for direction indication. On a top portion of the main electronic member, there are Bluetooth and power status LEDs whose lights are guided to the front by light pipes on the front frame member. The LED corresponding to the due south is lit in color green and the opposite LED corresponding to the due north is lit in color red. The two lit LEDs are always lined up and opposite to each other.

Claims

1. A Bluetooth GPS receiver with an electronic compass, comprising:
