Embodiment 1

[0013] Example 1. A kind of wireless mobile positioning communication module, can refer to figure 1 , figure 2 . figure 1 A structural block diagram of the present invention for position calculation is shown.

[0014] The positioning instruction control unit 100 is responsible for issuing a control instruction to start positioning. The positioning instruction 101 is transmitted to the component 301 and the component 401 respectively through the open interface (200) (CDMA 1X network) of the present invention.

[0015] Component 301 is a CDMA 1X cellular signal receiving component. After receiving the 201 instruction to start positioning, it performs receiving operations required for positioning based on the cellular network. This operation includes receiving the CDMA 1X carrier signal from the antenna 300, and obtaining the CDMA baseband signal through high-frequency signal processing, and decoding the baseband signal through a dedicated processing chip and software to ob...

Embodiment 2

[0023] Example 2. A wireless mobile positioning communication module. Its open interface 200 is one of RS-232 or USB interface. That is to say, the data transmission mode of the open interface 200 is realized through the RS-232 or USB interface, with a specially defined AT command and data transmission protocol. The rest are the same as embodiment 1.

Embodiment 3

[0024] Example 3. A wireless mobile positioning communication module. Its open interface 200 is a local data bus. That is, the data transmission mode of the open interface 200 is transmitted through the data bus inside the module. The rest are the same as embodiment 1.

Abstract

The present invention relates to a wireless mobile positioning communication module, belonging to the wireless positioning technology. It includes the components of positioning control instruction, open inferface, GPS receiver, GPS position intermediate information storage and position calculation equipment and position application component, the GPS position intermediate information storage component is connected with interface component, and can transfer the information into position calculation equipment by means of interface component. The interface component is connected with CDMA receiving component, and the CDMA receiving component also is connected with another position intermediate information storage component connected with interface component.

Description

technical field [0001] The invention belongs to the technical field of wireless positioning, and more specifically relates to the improvement of a wireless mobile positioning communication module capable of determining its current position through GPS and CDMA wireless signals. Background technique [0002] In modern positioning technology, traditional GPS receivers work well outdoors, but are less effective indoors or in places where other satellite signals cannot cover. Another positioning scheme relies on cellular networks, using cell tower signals to triangulate mobile devices. However, the effect of this solution is not satisfactory in areas with poor cell base station geometry or poor cell site coverage conditions. [0003] In the past, terminal products with position calculation functions were all closed structures and self-contained. Although it can provide location information services, it is often specially designed for a certain industry or a certain application...
