Beijing Aerospace Yuxing Technology Co., Ltd. (Chinese: 北京宇星科技有限公司), operating under the SpaceOK brand, is a Chinese commercial satellite tracking, telemetry, and command (TT&C) services company providing global space infrastructure operations for satellite operators. The company operates a global network of ground stations to deliver full-lifecycle TT&C services covering the satellite early orbit phase, long-term in-orbit management, and re-entry phase for satellites in low Earth, medium Earth, and geostationary orbits. SpaceOK provides commercial satellite measurement, control, and communication services to satellite operators seeking reliable, globally distributed TT&C coverage without building or operating proprietary ground station networks. The company participates in China's growing commercial satellite services sector, offering TT&C infrastructure to both domestic and international satellite operators as the country's commercial space industry and satellite fleet expand. SpaceOK's operations complement the on-orbit services market for China's growing number of commercial EO, communications, and technology demonstration satellite missions.
