About
The Jilin-1 SP series captures 4K high-definition colour video at 1.2 m resolution, enabling continuous dynamic monitoring for applications requiring real-time situational awareness. Unlike static-snapshot satellites, the video capability allows tracking of moving objects such as vessels, vehicles, and fire fronts. Operating from 650 km sun-synchronous orbit with ±45° side-slip, the constellation achieves a 3.3-day revisit cycle. Data is transmitted at 350 Mbps via X-band. Later iterations (SP03) improved ground pixel resolution to 0.92 m. Key markets include emergency response, disaster surveillance, maritime monitoring, and transportation.
