China's Shijian-31 Surveils GEO Belt From Custom Orbit, Space Brief 24 Jul 2026
China's Shijian-31 satellite is performing maneuvers in geostationary orbit that allow it to monitor other spacecraft, raising concerns from US Space Command. Meanwhile, the US defense industry faces pressure to meet a 2027 deadline for supply chain compliance regarding critical minerals.
Why it matters
The maneuvers highlight increasing tensions and surveillance capabilities in space, while supply chain constraints pose a challenge to national defense readiness.
Maurice Stellarski China's Shijian-31 Surveils GEO Belt From Custom Orbit, Space Brief 24 Jul 2026 China's Shijian-31 satellite operates in custom GEO orbit sweeping across geostationary belt rather than parking stationary, enabling repeated close surveillance of other operators' spacecraft.
China’s Shijian-31, launched in June, isn’t sitting still in a standard GEO slot. Analysts tracking the satellite say it’s flying a custom orbit that lets it sweep across the geostationary belt rather than parking at one longitude, giving it repeated close looks at other operators’ spacecraft.
That kind of orbit is a signature move for inspection and surveillance satellites. If Shijian-31 keeps cycling through GEO neighbors, expect more conjunction alerts and closer scrutiny from US Space Command as it passes near commercial and military birds.
