How Taiwan’s new AI satellite system aims to speed up early warning against PLA moves

Taiwan is set to acquire an AI-powered satellite imagery system designed to swiftly identify People's Liberation Army (PLA) vessels, aircraft, and missile launchers, according to a report by Taiwan's defence ministry. This NT$46.55 million (US$1.45 million) system, awarded to ThinkTron, a Taiwan-Japan joint venture specializing in AI and geospatial monitoring, is expected to be operational by the end of April 2024.

The Communication Development Office (CDO), a primary military intelligence unit, contracted ThinkTron to develop a prototype AI satellite imagery recognition system. This technology will allow Taiwan's military to rapidly search for and identify enemy forces and activities at military bases and other nearby locations. By automatically comparing new imagery with historical data, the system will flag changes for intelligence analysts to review.

The system's primary function is to use AI to analyze satellite images, which cover areas up to 100 square kilometers within minutes. This capability includes identifying vessels larger than 10 meters in length, as well as smaller targets such as aircraft, missile launchers, and radar vehicles. ThinkTron's "Tron Eyes" technology, which employs convolutional neural networks for imagery analysis, will be the foundation of this system.

Military analyst Zivon Wang from the Chinese Council of Advanced Policy Studies in Taipei clarified that this project differs from the acquisition of new reconnaissance satellites. The system will serve as an analytical layer, processing imagery obtained from other sources rather than operating the military-grade satellites. This distinction helps explain the relatively modest cost of the project, as building an entire satellite reconnaissance architecture would require significantly more investment.

Taiwan International Strategic Study Society executive director Max Lo noted that the underlying technology is mature and already used by advanced militaries and remote-sensing organizations. However, the significance for Taiwan lies in operationalizing the technology and integrating it with the island's existing intelligence capabilities.

Lo emphasized that even though the PLA is capable of installing AI systems directly on satellites, Taiwan's system will analyze the imagery on the ground at the CDO, which specializes in signals intelligence.

By cross-checking imagery analysis with signals intelligence, Taiwan's military can more quickly assess PLA exercises, changes in tactics and force deployments. This intelligence fusion could be particularly useful when monitoring large areas of sea, where synthetic aperture radar (SAR) detects vessels at night and through cloud cover, while optical imagery provides greater detail in clear daylight conditions.
