About
Kratos Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) antennas are precision engineered to provide stable, high throughput links to LEO and MEO constellations. These antennas are designed to work in open air without a radome, offering high pointing accuracy with low backlash. Their operation is controlled by Kratos’ NGC2 Controller, ensuring reliable and precise communication with orbiting satellites. The design emphasizes robust performance in various environmental conditions, eliminating the need for a protective radome.
