SkyARX Ku20

In equatorial regions, satellite communication systems face a unique challenge called the “keyhole effect.” This phenomenon occurs when traditional 3-axis antenna systems require extremely high speed and acceleration to maintain tracking with satellites as the elevation angle approaches 90 degrees. The effort needed to sustain this tracking becomes infinitely large at 90 degrees, making it a significant obstacle for airborne vehicles operating near the equator region.

To overcome these challenges, the SkyARX Ku-20 Qx Terminal introduces an innovative four-axis antenna system. This advanced design provides stabilization against disturbances occurring at 80-90 degrees, particularly in the roll axis for airborne vehicles. By incorporating a fourth axis, the system significantly reduces the effort required to maintain satellite tracking, ensuring stable and reliable communications even in the most challenging environments. With its cutting-edge technology and sophisticated waveform structure, the SkyARX Ku-20 Qx Terminal sets a new standard for satellite communication systems. Its ability to transmit live, high-definition video and secure data during operation offers significant advantages for both civilian and governmental users.

Experience the future of satellite communications with the SkyARX Ku-20 Qx Terminal—where innovation meets reliability.
