Communication satellites are cutting-edge technologies that enable communication between satellite communication earth stations or between earth stations and spacecraft. They are mainly used in communications, mobile communications, television broadcasting, maritime communications, tracking and data relay. In its rigorous R&D process, top-of-the-line vacuum pumps play a vital role, and vacuum equipment can be used for satellite testing to help achieve global communications.
The number of communications satellites currently being sent to space orbit is increasing. As a method of motion, modern spacecraft use so-called electric propulsion, in which ionized particles are accelerated within the ion thruster. These engines, typically fueled by helium, are a significant challenge for vacuum pumps because they require process pressure to be maintained in the high vacuum range while high energy ions are emitted at high flow rates. Vacuum experts provide optimized and simple solutions for helium pumping and produce large systems to test these electric propulsion units. Preparing these space tests can take several months, and the vacuum pump needs to provide constant performance, which requires where the expertise really comes into play. The vacuum and turbomolecular pumps first generate a high vacuum to remove interfering air. The high-efficiency cryopanel then freezes the helium that is emitted to the desired degree of vacuum. Automatic control helps engineers and scientists determine that the propulsion unit is ready for space preparation. In this critical and demanding application, communication satellite R&D institutions not only need high-professional technology as a support, but also a full-line supply chain of vacuum technology.
