Abstract

The invention discloses a positioning device based on a global positioning system (GPS)-ZIGBEE dual-mode positioning technology. The device comprises a GPS positioning module. The GPS positioning module is connected with a serial port of a singlechip. A first ZIGBEE module is connected to the singlechip, and is connected with a first receiving antenna. A second ZIGBEE module is also connected to the singlechip, and is connected with a transmitting antenna. A control unit and a power supply are also connected to the singlechip. The GPS positioning module is also connected with a second receiving antenna, and analyzes and decodes a received signal. The decoded signal is transmitted to the singlechip for processing, and the processed signal is transmitted to the first and second ZIGBEE modules for transmission or forwarding to other interfaces. After the signal is forwarded for many times, an upper computer processes received information and displays the processed information on a display. A ZIGBEE positioning system is automatically started under the condition that a satellite signal cannot be received. The positioning device has the characteristics of low power consumption, ultra long standby time, small volume, light weight, convenience of carrying and adaptability to various severe environments.

Description

technical field [0001] The invention belongs to the technical field of wireless positioning, in particular to a positioning device based on the dual-mode positioning technology of GPS and ZIGBEE. Background technique [0002] GPS is the abbreviation of Globle Positioning System, which means global positioning system. It is a huge space and aerospace project implemented by the US government after more than 20 years and costing 12 billion US dollars. The system can provide information to ground targets around the clock on a global scale, thereby determining the precise position, speed, operational aspects and other parameters of the target on the ground. [0003] Now, people are more and more aware of the important role of GPS and its broad application fields. In addition to military applications, it has been widely used in many fields such as aerospace, aviation, navigation, surveying, and detection. With the price of GPS receiving boards GPS is suitable for: car GPS system,...
