The Advanced Land Observing Satellite Daichi (ALOS) will be injected into orbit at an altitude of 692 km and make a round of the earth from the south to the north. While the Daichi (ALOS) flies south to north, the earth rotates to the east. As a result, the satellite can cover the whole surface of the earth. The Daichi (ALOS) will make one round in 99 minutes or 14 to 15 rounds per day. Under regular conditions, it can observe the whole earth in 671 rounds over 46 days maximum. In case of an emergency, the satellite can start observing a disaster-stricken area within two days by using the pointing function (or changing the observation direction of) the sensors.
