The BJ3N Advantage

4-Band Multispectral Imagery
BJ3N images include 1.2-meter (m) red, green, blue, and near-infrared (NIR) bands for multispectral analysis and change detection.

Crisp 30-cm Resolution
The BJ3N satellite enhances our 30-centimeter (cm) imagery offerings and grows our archive of exceptional-quality high-resolution imagery.

Impressive Collection Capacity
Collecting up to 500,000 square kilometers (sq km) a day, 30-cm BJ3N is amassing a sizeable archive of high-resolution satellite imagery.

Overview & HistoryBJ3N SpecificationsPricing

Launched into orbit aboard a Long March CZ-2D vehicle from Taiyuan, China on August 24, 2022, Twenty First Century Aerospace Technology’s BJ3N joins our pantheon of 30-cm high-resolution satellites. The panchromatic sensor collects imagery at 30-cm resolution, while the 4-band multispectral sensor, including blue, green, red, and near-infrared (NIR) spectral bands, collects at 1.2-m resolution. With an impressive daily collection capacity of 500,000 sq km, the BJ3N satellite rapidly images substantial areas of the Earth’s surface. Whether reviewing agricultural areas, monitoring urban growth, or analyzing environmental change, the BJ3N satellite offers considerable insights. With its powerful capabilities, BJ3N adds to our ever-growing archive of 30-cm resolution Earth imagery.
