Abstract: The present invention discloses a Bluetooth satellite receiver device powered by a cigarette lighter socket, which comprises: a cigarette lighter plug module, inserted into a cigarette lighter socket to obtain power from a vehicle; a power supply module, electrically coupled to the cigarette lighter plug module, and supplying power to the device; a satellite receiver module, electrically coupled to the power supply module; and a Bluetooth communication module, electrically coupled to the power supply module. The satellite receiver module receives the signals from a satellite in an orbit and then decodes the signals into a latitudinal and longitudinal information and sends the latitudinal and longitudinal information to the Bluetooth communication module. The Bluetooth communication module receives the latitudinal and longitudinal information and sends it out wirelessly. The user utilizes a portable electronic device having the Bluetooth receiver function to receive the abovementioned information.
