Satrec Initiative to build 10-centimeter-class optical satellites for Hanwha constellation

South Korea's Satrec Initiative, together with parent company Hanwha Systems, will build four satellites for Earth observation with 10 cm resolution. They will complement Hanwha's SAR constellation of 64 spacecraft, which by 2031 will provide a 30-minute revisit time.

• Satrec Initiative to launch four satellites with 10-cm class optics
• Hanwha constellation to include 64 SAR satellites with 30-minute revisit by 2031
• Spacecraft to operate in orbit below 400 km, test satellite around 500 km
• Image analysis to be provided by subsidiary SI Analytics using AI
