Abstract：In the application scenarios of positioning technology with high difficulty in target search such as space launch and sea salvage,in order to make up for the lack of lithium battery capacity and low efficiency of single power supply voltage manage-ment caused by objective requirements such as antenna power of traditional missile positioning devices,a positioning device with simple charge and discharge management,stable comprehensive performance and long-term operation is designed.The device is mainly composed of a positioning module,a main control module,a power supply management module,and a lithium voltage acqui-sition module.The positioning module is developed based on the Beidou system,the main control module is responsible for the pro-cessing of positioning data,the power supply management module includes lithium battery charging chips,relays,etc.,which can artificially control its power supply working mode,and the lithium voltage acquisition module is responsible for real-time monitoring of lithium battery voltage.After testing,the average positioning error of the positioning device is stable at 3 m～5 m,a single dis-charge can work continuously for more than 5 hours,and the voltage of the lithium battery changes linearly during the charging pro-cess,which has the characteristics of small size and stable and reliable operation.
