In war, disaster relief, polar research, etc.Extreme scenariosThe antenna turntable is the core equipment for communication, navigation and target tracking. For example, in military operations, the radar antenna turntable needs to be in -40 ℃ to 70 ℃ temperature difference, strong electromagnetic interference environment, to 0.01 ° precision real-time locking high-speed moving targets; in the polar scientific research, the equipment needs to withstand 10 strong winds and salt spray corrosion, to ensure that the satellite signal stable transmission.

Battlefield and Disaster Scenes:

Core Challenges of Antenna Turntable Drive Systems

In the context of the escalation of non-traditional security threats (geopolitical conflicts, frequent occurrence of extreme meteorological disasters) and accelerated iteration of polar scientific research equipment, the highly reliable antenna rotary, as the core carrier of satellite communication link construction, radar accurate positioning and emergency signal relay, has become a strategic level equipment to ensure the stability of key information nodes. Its millisecond response capability directly determines the command and scheduling effectiveness and the upper limit of disaster damage control in extreme scenarios, which is specifically manifested as follows:

Satellite communications safeguards

When the fiber optic cable is interrupted and the base station is damaged, the space-based signal transmission relies on the rotary station to accurately track the satellite trajectory, such as in the scene of floods, earthquakes and other large-scale disasters, the satellite rotary system becomes the only communication channel between the disaster area and the outside world.

Extreme environments such as polar research

It needs to withstand the harsh working conditions of -50℃ polar low temperature to 70℃ desert high temperature, as well as heavy rain, sand and dust and other extreme climate. For example, in the Antarctic research station equipment needs to be in 60 ℃ temperature difference (-40 ℃ to 20 ℃) under continuous operation, the traditional reducer is easy to lubricant coagulation caused by transmission failure.

Military grade reliability

Ensure continuous signal locking under the complex electromagnetic environment during wartime, with extremely high demand for signal transmission accuracy and harsh environment in the war zone. For example, when UAV swarms operate together, they need to track targets hundreds of kilometers away in real time through radar antennas, and the transmission system needs to maintain extremely high precision under the low temperature of -40℃ plateau.
