Objectives of the Product

HAPSEYE is an ESA InCubed-supported project led by ICEYE Spain to develop a solar-powered High Altitude Pseudo-Satellite equipped with a SAR payload. Operating at more than 20 km in altitude, HAPSEYE complements ICEYE’s satellite constellation by providing continuous monitoring with near real-time data transmission.

Through a series of incremental prototypes, the project advances towards a Minimum Viable Product (MVP) at TRL7. HAPSEYE enhances Europe’s autonomy in Earth observation, bridging gaps left by satellites due to limited revisit rates or capacity bottlenecks. Its applications include disaster response, flood and wildfire monitoring, and national security.

This activity consolidates ICEYE’s Spanish hub in Valencia, creating new high-skilled jobs and strengthening the European aerospace supply chain. With support from ESA, national regulators and key customers HAPSEYE is positioned to become the first European SAR-tailored HAPS platform, delivering unique added value in resilience, flexibility, and cost-effectiveness.

Customers and their Needs

HAPSEYE targets government agencies, emergency management organisations, insurers, reinsurers, and defence entities. These customers require persistent, timely, and reliable Earth observation data to support disaster management, infrastructure monitoring, and security operations.

Insurance and re-insurance customers have expressed strong interest in validating HAPSEYE results during development. Governments require enhanced situational awareness during crises.

Targeted customer/users countries

Spain, Greece, USA, Australia, Japan.

Product description

HAPSEYE is a solar-powered unmanned aerial platform designed to operate in the stratosphere for months at a time. It carries a Synthetic Aperture Radar payload, providing near-continuous coverage of selected regions with very high resolution.

Main features:

• Continuous coverage above 20 km altitude, staying out of adverse weather conditions.
• Flexible deployment, loitering above crisis areas, and integration with ICEYE’s satellite fleet.
• SAR data collection and delivery within ~3 hours when combined with ICEYE ground segment.
• MVP platform capable of year-round flight and extended operational latitudes

Innovation aspects: dedicated SAR-only payload, agile prototyping cycles, and European development (avoiding ITAR restrictions). Customers interact via ICEYE APIs, portals, or tasking services, integrated with existing data pipelines

Added Value

HAPSEYE uniquely combines persistence, high-resolution imaging, and resilience:

• Versus satellites: Provides continuous monitoring of a region instead of periodic revisits.
• Versus aircraft/UAVs: Much longer endurance (months), lower operational costs, and weather resilience.
• Versus competitors: SAR-only focus ensures optimisation for radar missions

The integration with ICEYE’s SAR constellation and Solutions products makes HAPSEYE a key enabler of faster disaster response and improved risk assessment. Its European development secures autonomy in critical Earth observation capacity.
