Systems that can transmit high-altitude, real-time disaster area image information via a geosynchronous orbit satellite to relevant emergency organizations when disasters occur are under consideration. Mitsubishi Electric is developing an active phased array antenna*1 for use in helicopter on-board satellite communication, and has supplied some to NICT*2. This cutting-edge antenna and the high-frequency circuit technology used make the equipment smaller and thinner than conventional systems.

Using this active phased array antenna technology enables instantaneous and non-stop electronic communication with satellites, even when the helicopter's position changes.

In addition to small, lightweight antenna components*3, which can be easily mass produced, we are developing high-frequency circuits that have the world's highest-density wiring.

We will improve the antenna gain by developing novel antenna element arrangement and ensure high-quality moving image transmission with reducing interference to the other satellites.
