Featured Product – 50-cm 4-Band BJ3A

Have you seen 50-centimeter (cm) 4-band BJ3A in Image Hunter recently?

If not, you need to query the archive now as 50-cm BJ3A is one of the crispest 50-cm satellites on the market! Launched by Singapore-based Twenty First Century Aerospace Technology on June 11, 2021, the BJ3A satellite collects 50-cm resolution panchromatic data and 2-meter (m) resolution multispectral data, including red, green, blue and near-infrared bands. With a swath width of 23.5-kilometers (km), BJ3A can collect an impressive 750,000 sq km a day. You can learn more about BJ3A on our website and search the BJ3A archive on Image Hunter.
