Summary
The TJS-14 satellite, also known as Tongxin Jishu Shiyan 14, is a classified Chinese communication technology experiment satellite believed to potentially serve military purposes such as missile warning or signals intelligence. It was launched on January 23, 2025, from the Xichang Satellite Launch Center using the Long March 3B launch vehicle. The satellite has dimensions of 5 meters in length and 2.5 meters in diameter with a span of 30 meters due to its two panels. Its dry mass is 2500 kg, and it weighs 5000 kg at launch. TJS-14 is owned by the People's Liberation Army Strategic Support Force (PLA SSF) and manufactured by the Shanghai Institute of Satellite Engineering (SISE). It reached geostationary orbit shortly after its launch date and commenced operations, featuring a box shape with two panels, silver aluminum cladding, and three-axis stabilization for orientation control. The satellite’s structure is primarily composed of aluminum and magnesium alloys. TJS-14 is part of the Tongxin Jishu Shiyan series and has several related satellites including TJS-1 through TJS-13. No specific transmitter frequencies have been publicly disclosed.
