Embodiment Construction

[0020] Such as figure 1 As shown, a GPS information forwarding device is installed on the roof of a car or in an area where the GPS satellite signal is weak or where the GPS satellite signal cannot be received, so that the car navigator can continue to exercise its navigation function, including the following components:

[0021] GPS receiving module: The GPS receiving module adopts the existing standard GPS receiving module (such as the GA613 of Zhejiang Zhengyuan Electric Co., Ltd.). This module is an optional component. When the GPS information forwarding device is installed on the vehicle, generally It is installed on the top of the vehicle. At this time, the transponder can be moved and the GPS receiving module is enabled. The GPS receiving module receives dynamic GPS satellite signals and demodulates them, and outputs the demodulated signals to the microcontroller.

[0022] Storage module: This module is also an optional component for activation. When the GPS informatio...

Abstract

The invention discloses a GPS information retransmission device. The device comprises a GPS receiving module, a storage module, a microcontroller and a wireless transmission circuit, wherein the GPS receiving module is used for receiving and demodulating a dynamic GPS satellite signal and outputting the demodulated signal to the microcontroller; the storage module is used for storing fixed geographical position information of the GPS information retransmission device; the microcontroller is used for reading the fixed geographical position information of the storage module or processing the demodulated GPS satellite signal sent by the GPS receiving module, extracting and obtaining dynamic geographical position information of the GPS information retransmission device, controlling the wireless transmission circuit, and transmitting the fixed geographical position information or the dynamic geographical position information to a navigating instrument; and the wireless transmission circuit is used for transmitting the fixed geographical position information or the dynamic geographical position information sent by the microcontroller to the navigating instrument. The GPS information retransmission device can effectively avoid signal interference, and is convenient to use.

Description

technical field [0001] The invention relates to a positioning auxiliary device for a vehicle-mounted portable navigator, in particular to a GPS information forwarding device. Background technique [0002] At present, the vehicle-mounted portable navigator (hereinafter referred to as the navigator) is a professional device that receives GPS (Global Positioning System) satellite signals, performs precise geographic location positioning, cooperates with the navigation map, and provides driving route planning and driving process navigation. Although the positioning accuracy of GPS satellite positioning is high, it can only be positioned under the premise that the navigator can receive signals from multiple GPS satellites. When the signal disappears and the signal is recaptured (for example, the vehicle comes out of the garage), it will take a certain amount of time to locate; or when the navigator is in the back seat of the car, the GPS signal is far inferior to that in the fron...
