#CMT# #/CMT# The receiver has a main electronic unit (2) with a satellite antenna (20), and a set of lighting emitting diodes (LEDs) (2000, 2001) disposed on the unit. A start-stop switch (21) is disposed on a unit side. A set of status LEDs (22, 23) indicating power and wireless transmission statuses is disposed on an upper part of the unit. A battery module (5) placed on the rear of a rear housing element (4) is covered by a battery cover (7). An electronic compass module (25) of the unit illuminates the LEDs relative to north and south poles in appropriate colors based on magnetic field from the earth. #CMT# : #/CMT# The electronic unit receives a global positioning system (GPS) radio signal and transmits the information received using a Bluetooth protocol. #CMT#USE : #/CMT# Used for providing navigation and position information to a user. #CMT#ADVANTAGE : #/CMT# The electronic compass module illuminates the LEDs relative to north and south poles in appropriate colors based on magnetic field from the earth for indicating the directions to the user. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a global positioning system receiver. 2 : Main electronic unit 3 : Front housing unit 4 : Rear housing element 5 : Battery module 7 : Battery cover 20 : Satellite antenna 21 : Start-stop switch 22, 23 : Status LEDs 25 : Electronic compass module 2000, 2001 : LEDs. |
