H-II launch vehicle

ADEOS will be launched by an H-II launch vehicle from Tanegashima Space Center. Ninety seconds after the lift off, the H-II vehicle will separate its solid rocket boosters, and 6 minutes after liftoff, it will separate its first stage. Then, 16 minutes after liftoff, ADEOS will separate from the second stage.
After this separation, ADEOS will turn slowly. Then, ADEOS will spin down and deploy the Solar Array Paddle, and will automaticly establish a three axis stabilized attitude.

Initial Operation Sequence

ADEOS will deplay an IOCS unit, NSCAT antennas, and OCTS radiant cooler cover by commands sent from the ground station. Next, all sensors and units will be checked, and then ADEOS will be maneuvered into its proper orbit. ADEOS will be placed into a sun synchronous, subrecurrent orbit.

World's Ground Stations For ADEOS and JERS-1
In its operational phase, ADEOS will be operated by an observertion plan made at the gound station. The command plans for operations will be sent from the ground station once or twice a week. The On-Board Commputer will carry out the commands of the plans, then operate them.

The data gathered by the sensors is transferred to the ground station directly or recorded by the Misson Data Recorder and reproduced later.

ADEOS has an IOCS unit, which allows data to also be transmitted via the relay satellite.
