HELSINKI — Recent data reveals that U.S. satellites are closely monitoring Chinese spacecraft in geostationary orbit. Commercial space tracking provider Comspoc reported that USA 324 and USA 325, part of the U.S. Geosynchronous Space Situational Awareness Program (GSSAP), skillfully coordinated maneuvers from March 14 to 18. They were tracking China’s Shijian-29A and 29B satellites.
Geostationary orbit (GEO) is a fascinating area about 35,786 kilometers above the equator. In this orbit, satellites match Earth’s rotation, allowing them to maintain a fixed position relative to the Earth. By adjusting their orbits slightly, satellites can drift west or east along this belt, making it easier to reposition themselves.
During the operations, USA 324 and USA 325 positioned themselves strategically on opposite sides of the Chinese satellites. This allowed them to collect valuable data from two different angles. After four days of observation, they successfully completed a surveillance handoff, ensuring continuous monitoring of the Shijian satellites.
By March 19, USA 324 had closed the gap to around 63 kilometers from Shijian-29A, a close distance that could enable detailed observation. Meanwhile, USA 325, which had been tracking the Chinese satellites since early January, shifted its position on March 18, completing the handoff.
Launched in late December 2025 on a Long March 7A rocket, the Shijian-29 duo is part of China’s experimental satellites. However, their exact capabilities remain cloaked in mystery. China’s state-owned aerospace contractor, CASC, mentioned that these satellites are primarily for testing new technologies in space target detection.
This context raises questions about the nature of U.S.-China satellite interactions. Experts characterize these maneuvers as “inspectors watching inspectors,” suggesting heightened vigilance in space. But the precise roles and technology of the Shijian satellites are still largely unknown, adding to the intrigue.
Ground observations from s2a Systems, a Swiss space surveillance firm, have noted that Shijian-29A appears significantly brighter than Shijian-29B, which could be due to differences in their size, shape, or coatings. These findings add another layer to understanding the ongoing space race.
The situation is part of a broader trend among major spacefaring nations, especially the U.S., China, and Russia. With an increase in satellite capabilities to conduct proximity operations, the lines between peaceful observation and potential military applications are becoming increasingly blurred.
This ongoing evolution in satellite technology and monitoring techniques highlights the importance of space situational awareness. As nations continue to develop advanced capabilities, understanding the implications of these maneuvers is crucial for future security in space.
