Next-generation mid-size satellites 3D model

Next-generation mid-size satellites No. 1 and No. 2 (stage 1), which are developed independently by South Korea, are standard models of South Korea's mid-size satellites equipped with high-resolution (black and white 0.5-meter, color 2.0-meter) electro-optical cameras. Next-generation mid-size satellites No. 1 and No. 2 have a solar synchronous orbit at an altitude of 497.8 kilometers, weigh around 500 kilograms, and have a mission life of four years. The payload has an observation width of 12 kilometers, a 1Tbit video storage capacity, and a 640Mbps transmission speed. No. 2 will be operated with a phase difference of 180 degrees compared to No. 1 in the same orbit as No. 1.
