The Application of Slip Rings in Satellite Systems

Satellites have extremely high value in both civilian and military applications, widely used in scientific research, meteorology, communication, navigation, military reconnaissance, ocean surveillance, and other fields. And compared to base stations on Earth, it has the advantages of large communication capacity, high transmission quality, good maneuverability, and strong survivability.

A geostationary satellite can cover one-third of the Earth, so the range covered by the satellite is not comparable to equipment on the ground. Satellite navigation systems can provide users with high-precision positioning and navigation 24/7.
The Application of Slip Rings in Satellite Systems
In order to protect the body and perform tasks, satellites require rotation and multiple relative movements. In order to ensure the normal operation of the rotating parts, energy and signal sources need to be transmitted to the rotating parts during the rotation process, such as electrical energy, fluid pressure energy, fiber optic signals, high-frequency signals, etc. The function of the slip ring is to establish a connection between electrical energy and signals between the rotating and fixed parts of the satellite, ensuring the normal operation of the rotating parts. Therefore, although the slip ring accounts for a small proportion in the overall system, it is also an inseparable part of the satellite.

Due to the special working environment of satellites, the selection of slip rings must be able to withstand high and low temperatures, and a satellite can only be returned to the ground after working in its orbit for 20 years. The slip rings used by satellites must have the characteristics of long service life and maintenance free.
