The European Union has ordered a 24-hour delay in the release of imagery from its Copernicus program, specifically targeting data from Sentinel-1 and Sentinel-2 satellites over the Gulf of Oman. The restricted area encompasses critical shipping lanes leading to the Strait of Hormuz, a focal point in the ongoing military tensions between the U.S. and Iran.

A strategic shift in open data policy

The Copernicus program is globally recognized for its free and open data policy, which has empowered scientists and commercial entities to monitor Earth's environment without barriers. However, a Council of the EU decision signed on July 13 by President Kaja Kallas creates a significant exception. This move follows a diplomatic request from U.S. authorities on May 26, processed through the EU’s Space Threat Response Architecture.

The Council argues that this delay is essential to prevent third-party states or non-state actors from exploiting satellite products in ways that could threaten the interests of the EU and its allies. While a European Commission spokesperson described this as a "routine technical measure," it represents a departure from the EU's commitment to unrestricted data access.

Impact on the geospatial market

This decision undermines recent efforts by European Earth observation companies to position themselves as a transparent alternative to U.S.-based providers. Until recently, firms like Kayrros had seen an influx of business from energy traders and insurers who turned to European data after U.S. companies, including Planet and Vantor (formerly Maxar), imposed strict restrictions or indefinite withholdings of imagery over Iran.

The move highlights the tension between Europe's desire for strategic autonomy—evidenced by projects like IRIS²—and the practical realities of security alliances during global conflicts.

The criticality of Hormuz monitoring

The strategic value of this data is evident in recent reports. Copernicus imagery has been instrumental in tracking "dark ships" and illegal oil transfers near Fujairah and Sohar, as well as detecting oil leaks from sanctioned vessels like the Caroline Bezengi. By introducing a 24-hour lag, the EU limits the ability of global observers to track naval movements in real-time through one of the world's most volatile oil chokepoints.
