Beidou global global "centimeter-level" positioning system construction work started

Posted on

China Aerospace Science and Technology Group held a press conference at the Zhuhai Air Show on the 1st, announcing the launch of China's first Beidou global "centimeter-level" positioning system. The system was named "Jianlong System". According to reports, the Xiaolong system calculates the orbital error and clock error parameters that have a great influence on the positioning accuracy in the traditional satellite navigation and positioning by calculating the observation data obtained from more than 300 multi-system satellite navigation reference stations in the world. Precision correction, and through the 5 geosynchronous orbit satellites and more than 60 low-orbit communication satellite constellations, broadcast relevant correction parameters to the satellite navigation terminal, and improve the positioning accuracy of the satellite navigation terminal to "centimeter level".

The Snapdragon system provides four kinds of data signals, OS, SP, GP, and Air, which provide "Yami, Sub-meter, Cm, and Aviation Safety" services. According to the press conference, with the gradual advancement of the construction and operation of the Xiaolong system, China's industrial sector will have a "small scale that perceives the world in centimeters."

Lithium Fluorinated Carbon Batteries Of 14250

BR series battery is lithium carbon fluoride battery,large capacity cylindrical batteries.
The cylindrical lithium carbon fluoride batteries independently developed and produced by DADNCELL have models such as BR18650, BR14250 and BR14500.
Lithium fluorocarbon battery BR18650/BR14250/BR14500 has high electric capacity (the capacity of 18650 model is 5Ah), wide operating temperature (-40 ~ +125℃), long shelf life (10 years, self-discharge ≤0.5%/year) , Good safety performance (through acupuncture test) and other characteristics. Therefore, it is widely used as equipment batteries in extreme environments, aerospace, conservation animal tracking, toy products, power tools, portable energy, emergency equipment and backup power supplies.
The performance of the lithium fluorocarbon cylindrical battery is the same as that of the lithium fluorocarbon soft pack battery, but the packaging is different.
