The magnetic survey department of Beijing Jozzon Space Technology Development Co., Ltd., whose predecessor is the "magnetic measurement laboratory of Space Science and Applied Research Center of Chinese Academy of Sciences, is an enterprise engaging in developing a variety of technology and products concerned with detection of weak magnetism. For many years, its three-axis fluxgate magnetometer product has been widely applied for measuring satellites’ attitude on the orbit; The another product magnetic torquer has been used for attitude control. Its patent-amorphous alloy core magnetic sensor is characterized by high sensitivity, quick response, very small size and low power consumption and can be to detect uncontactly current leak and micro proximity as well as collision-proof of vehicles. In order to meet market needs, we developed Inclination and azimuth sensor that high temperature and shock and vibration resistance for oil drilling wireless measurement system.

The "Environmental Magnetic Field Mapping Method", invent by magnetic survey department, used to measure satellite remaining magnetic moment in geomagnetic field, has solved the major problem in measuring magnetic moment of the whole star without large-scale zero magnetic field apparatus,. Thus, the method won the first prize of former Ministry of Aerospace Industry and Technology Progress Award, and is still in use so far.
