Satellite tracking systems and self-steering antennas are used aboard ships, vehicles, or aircraft to maintain contact with satellites. These units are portable, can operate unattended for months, and can be adapted to different commercial and military applications and frequency bands.
Electronic tracking and beam switching is used, not mechanical tracking, so there are no mechanically moving parts. This approach is rugged, cost-effective, eliminates the inertial time lag of mechanical tracking and the effect of wind on beam pointing, and provides much more rapid tracking response.
