\u2003The Japan Aerospace Exploration Agency (JAXA) successfully completed the critical operations phase*1<\/sup> of the Advanced Land Observing Satellite-4 “DAICHI-4” (ALOS-4). *1: <\/p>\n \n Critical operations phase *2: <\/p>\n \n PALSAR-3 *3: <\/p>\n \n SPAISE3 *4: <\/p>\n \n Initial functional verification operations phase \t\t<\/div>\n
\u2003JAXA received telemetry data confirming that a series of planned operations, including the deployments of the
\n solar array paddles and the antennas of mission payloads (the Phased Array type L-band Synthetic Aperture Radar-3
\n (PALSAR-3) *2<\/sup> and the SPAISE3*3<\/sup>), has been
\n completed, and that the satellite is in a stable condition to remain in orbit. With this confirmation, the critical
\n operations phase of “DAICHI-4” was completed.
\u2003”DAICHI-4″ will move on to the initial functional verification operations phase*4<\/sup>, to verify the functions of the onboard instruments over a period of approximately
\n three months.
\u2003JAXA conveys a deep appreciation for the cooperation and support of everyone involved in the launch and
\n tracking and control of “DAICHI-4” , including the government agencies, the prime contractor, Mitsubishi Electric
\n Corporation, and all the companies and organizations involved in the development, manufacture and operation of the
\n satellite.\n <\/p>\n<\/div>\n
The period after the satellite separation from the launch vehicle, to deploy the solar array paddles and the
\n antennas of mission payloads (the Phased Array type L-band Synthetic Aperture Radar-3 (PALSAR-3) and the SPAISE3),
\n and to transfer the satellite to an operational state.\n <\/p>\n<\/p><\/div>\n<\/div>\n
PALSAR-3: Phased Array type L-band Synthetic Aperture Radar-3 is a sensor that obtains information by transmitting
\n radio waves to the earth’s surface and receiving the radio waves reflected from the surface.\n <\/p>\n<\/p><\/div>\n<\/div>\n
SPAISE3: SPace based AIS Experiment 3 is a sensor that receives signals from the Automatic Identification System (AIS) installed on ships.\n <\/p>\n<\/p><\/div>\n<\/div>\n
