Polish SAR satellite reaches orbit: EYCORE-1 marks a milestone for maritime intelligence

The satellite was deployed aboard a Falcon 9 rocket operated by SpaceX, lifting off from Vandenberg Space Force Base in the United States. The mission was part of a broader commercial rideshare, placing multiple payloads into orbit.

Early operations confirm mission progress

According to the company, all critical early mission phases have been successfully completed. EYCORE-1 separated correctly from the launch vehicle and established initial communication via the S-band—one of the most failure-prone stages in any satellite mission.

Initial telemetry indicates that onboard systems are functioning nominally. Power systems have been activated, batteries are fully charged, solar arrays are generating current, and the satellite’s attitude has been determined with precision. These milestones confirm a stable transition into early orbit operations.

SAR capability: a strategic asset for maritime domains

What sets EYCORE-1 apart is its SAR payload. Unlike optical satellites, SAR systems can capture high-resolution imagery regardless of cloud cover, weather conditions, or time of day. For maritime stakeholders, this capability is particularly valuable.

Potential applications include:

• continuous vessel monitoring, including in low-visibility conditions,
• detection of illegal, unreported, and unregulated (IUU) fishing,
• surveillance of critical offshore infrastructure such as wind farms, pipelines, and LNG terminals,
• environmental monitoring, including oil spills and storm impact assessment.

In regions such as the Baltic Sea—where cloud cover frequently limits optical observation—SAR-based intelligence can significantly enhance situational awareness.

International collaboration, domestic innovation

The mission has been carried out in cooperation with Kongsberg NanoAvionics, which provided the satellite platform, and Exolaunch, responsible for integration and deployment services.

While the project reflects the inherently international nature of today’s space industry, the core radar technology has been developed in Poland by EYCORE’s engineering team. This positions the company—and the broader Polish ecosystem—as an emerging player in the global SAR market.

Commissioning phase now underway

Despite the successful launch and early contact, the mission now enters its most technically demanding stage. Over the next four to six weeks, engineers will conduct in-orbit commissioning and calibration of key subsystems.

This phase will include:

• validation of the attitude determination and control system (ADCS),
• testing of the propulsion subsystem,
• verification of high-rate data downlink via X-band,
• and, critically, activation and calibration of the SAR payload.

Only after these steps are completed will EYCORE-1 be considered fully operational and capable of delivering commercial data services.

Implications for the maritime sector

The successful deployment of EYCORE-1 underscores the growing role of private space companies in delivering actionable intelligence for maritime industries. For Poland and the wider Baltic region, access to sovereign or commercially controlled SAR data streams could enhance both economic activity and security capabilities.

As offshore energy, port infrastructure, and maritime logistics continue to expand, demand for reliable, all-weather Earth observation is expected to grow. EYCORE-1 may represent not only a technological milestone, but also the beginning of a new data-driven layer in maritime operations.

With commissioning underway, the industry will now be watching closely for the first radar images—arguably the true test of mission success.
