In an era defined by escalating competition in outer space, China has publicly demonstrated its advanced satellite surveillance capabilities by releasing images of a U.S. satellite observing its own space station. This move is viewed by analysts as a calculated response in an increasingly tense space domain.
The Jilin-1 satellite constellation, operated by Chang Guang Satellite Technology, captured images of the WorldView Legion satellite on September 8. The images were taken from distances ranging between 40 and 50 kilometers (approximately 25 to 31 miles). These images were subsequently published on the company's social media channels, marking the first time Chang Guang has publicly shared such dynamic, space-based imagery.
This action follows an earlier instance where Maxar Intelligence, a U.S. commercial remote sensing company, released images of China's Shijian-26 satellite. These images, captured by the WorldView Legion satellite on June 3, were taken from distances of 29 kilometers (18 miles) and 74 kilometers (46 miles), with resolutions of 1.9 cm and 4.9 cm respectively. The high-resolution imagery provided detailed views of the satellite's structure.
Susanne Hake, a general manager at Maxar Intelligence, commented that the Shijian-26 represents China's newest generation of optical reconnaissance satellites. She added that the clarity of the imagery signaled a new era in orbital observation. Maxar Intelligence has also previously released images of China’s Tiangong space station and the International Space Station at a resolution of 10cm.
The Intensifying Space Race
Military analysts suggest these recent events highlight a growing space race, fueled by advancements in satellite tracking, positioning, and high-precision imaging technologies. The ability to observe and track other satellites in space is becoming increasingly critical.
Reverse observation of surveillance satellites necessitates real-time acquisition, identification, and tracking of targets in space. This capability is crucial for providing rapid and accurate early warning of orbital activities. Chang Guang Satellite, China's first commercial remote sensing company, currently operates over 100 Jilin-1 satellites in orbit. These satellites can achieve resolutions of up to 0.5 meters and revisit any point on the globe within 10 minutes.
The company is also focused on developing large-scale satellite constellation networks, with an annual production capacity of 200 remote sensing satellites and 200 communication satellites. Last year, Chang Guang Satellite successfully conducted ultra-high-speed laser communications tests, achieving data transfer rates of 100 gigabits per second between satellites and ground stations.
Militarization of Outer Space
This technological competition is unfolding against the backdrop of escalating militarization of outer space. The United States established the U.S. Space Force in 2019 as its sixth independent military branch. In response, China formed the People's Liberation Army Aerospace Force in April of last year. This unit participated in a large-scale military parade in Beijing earlier this month. Chinese officials describe the unit as dedicated to the peaceful use of space and enhancing safe access to and utilization of outer space.
However, international tensions over space operations have surfaced in the past. In 2021, SpaceX's Starlink satellites twice approached the Chinese space station, forcing evasive maneuvers in July and October of that year. China urged the U.S. to take immediate measures to prevent similar incidents and to respect the international space legal framework.
The Technical Challenges and Strategic Implications
Imaging another satellite presents significant technical challenges due to the extremely high relative velocities involved. This requires exceptional pointing and tracking control. Such capabilities are not only critical for space object identification, monitoring, and anti-satellite operations validation but also carry significant strategic deterrence value.
Some analysts have suggested that these capabilities, combined with laser weapons, could pave the way for satellite-based offensive and defensive engagements in the future.
The Need for Norms and Regulations
As space becomes an increasingly important arena for strategic competition, analysts warn of the urgent need to establish effective norms of behavior to prevent escalation into conflict. The current lack of clear regulations and agreed-upon protocols raises concerns about potential misunderstandings and miscalculations that could lead to dangerous confrontations in orbit. The development of international agreements and cooperative frameworks is seen as essential for ensuring the long-term stability and peaceful use of outer space.
