With an aim to map globe every two weeks, hence, allowing authorities to act quickly to natural disasters, monitoring shipping lanes and observing agriculture yields, a Japanese satellite with eagle-eyed synthetic aperture radar was launched on Saturday.

Around 2.3 ton weighing spacecraft was launched at 0305:14 GMT from the Tanegashima Space Center, Japan's main rocket launching facility. The H-IIA Launch Vehicle No. 24 with the Advanced Land Observing Satellite-2 (DAICHI-2) or ALOS-2 was launched by Mitsubishi Heavy Industries and the Japan Aerospace Exploration Agency (JAXA).

After around 15 minutes and 47 seconds of its liftoff, the launch vehicle flew without any problem. Authorities concerned confirmed DAICHI-2 separation. ALOS-2 has been designed to last for five years and follows Japan's earlier land mapping mission, which worked from 2006 to 2011 and then suffered a disastrous power failure.

The first ALOS satellite had an optical stereo camera system, L-band radar and a radiometer. With the ALOS 2 satellite, the ALOS 2 satellite ensured to come up with advanced technology having updated version of the L-band radar.

ALOS-3 is also ready and will be launched in 2016. Before ALOS-2 starts its main job, it has to complete a three-step procedure to set up the satellite's L-band band microwave radar antenna. The spacecraft built by Mitsubishi Electric Co., will get operational in sometime this fall.

Shinichi Suzuki, ALOS 2 project manager said if things need to be said in short then ALOS-2 will also viewing an area needed to be observed much more quickly than before. "In most cases, the satellite will be able to observe an area in Japan's vicinity within 12 hours of a request ... and an area elsewhere in Asia within 24 hours", said Suzuki.
