Recently, the "Tianwen-1" Mars probe successfully implemented ground fire transfer. The Kashgar Deep Space Station of the Xi'an Satellite Control Center and the Jiamusi Deep Space Station provided full measurement and control support for it.

The farthest detection distance of the Mars rover is nearly 400 million kilometers, and the ground fire transfer time is nearly 7 months, which is also an unprecedented test for the measurement and control communication system.During the fire transfer of the "Tianwen-1" Mars rover, China's first deep space antenna array system will be officially put into use.

The deep space antenna array is composed of four 35-meter-diameter antennas. The azimuth bearings of the antenna equipment are all developed by the Heavy Bearing Division of Luoyang Bearing Research Institute Co., Ltd.. The slewing bearing size is close to 6 meters, and the working conditions are harsh. It needs to be able to operate under complex environmental conditions such as cold, humidity, corrosion and high temperature. It requires high precision, low starting friction torque and good rigidity.

With the continuous construction of the domestic deep space antenna array, Luoyang Bearing Research Institute Co., Ltd. will continue to exert its strength in the development of special bearings and slewing bearings to help China's deep space detection capabilities continue to leap.
