QPS-SAR-6 “AMATERU-III” has achieved azimuth resolution 1.8m and range resolution 0.46m at its first light images

Fukuoka, JAPAN – July 13th , 2023- Institute for Q-shu Pioneers of Space, Inc. (iQPS) released its first light images from QPS-SAR-6, named “AMATERU-III” which was launched on June 12th (US UTC) by SpaceX Falcon 9 Transporter-8 Mission. After a month of calibration, AMATERU-III demonstrated its capability to achieve ground plane resolution of azimuth direction 1.8m and range direction 0.46m (46cm) at its Stripmap mode first light image, which surpasses iQPS’ own record of the highest resolution for a commercial SAR satellite in Japan.

iQPS will enhance image quality further by fine-tuning satellite attitude control and commence observations in Spotlight mode (high-resolution mode) which will achieve both azimuth and range resolutions of 0.46m.

Shunsuke Onishi, CEO message

Since QPS-SAR-3 and subsequent satellites had been upgraded to establish a satellite constellation, the acquisition of images by QPS-SAR-6, marking its return after QPS-SAR-2, was a crucial milestone in the provision of near-real-time data services. We all are relieved that this day has come. I am very proud and confident of the skill and solidarity of our development team, our partners, and our operations team who calibrated the satellite in a smooth and speedy manner. I would like to express my sincere gratitude to our valued shareholders, whose unwavering support has been instrumental in our project and to all those who have eagerly anticipated the commencement of our data business. Now we strive to observe in high-resolution mode so that we can present you soon with images at 0.46m resolution.
