Sirb-1 Advances to Manufacturing as UAE’s Radar Satellite Programme Passes Critical Milestone

The UAE's national Synthetic Aperture Radar satellite programme has cleared its most significant design validation, positioning the nation to develop sovereign Earth observation capabilities and strengthen its domestic space industry.

The intricate machinery of space exploration demands precision at every stage, and the moment a satellite design passes its critical review marks a threshold where theory transforms into hardware. The Sirb-1 satellite programme has now reached that pivotal point, having completed its Critical Design Review and receiving clearance to advance into manufacturing, assembly, integration and testing.

Led by the UAE Space Agency and delivered through a national consortium anchored by FADA, the space entity of EDGE, Sirb-1 represents a distinctive approach to space capability development. Rather than relying solely on international providers, the programme places Emirati companies and national talent at its centre, building competitive expertise in radar imaging technology that few nations possess.

Synthetic Aperture Radar satellites function differently from their optical counterparts. By transmitting their own radar signals, they capture imagery of the Earth’s surface in conditions where conventional satellites cannot: through darkness, cloud cover, haze and dust. This capability unlocks applications across environmental monitoring, agricultural assessment, maritime surveillance, infrastructure management and humanitarian response during disasters.

The Critical Design Review process represents the final major design validation before flight hardware manufacturing begins. The review board, composed of engineers from the UAE Space Agency and partner organisations, rigorously assessed Sirb-1’s design against mission requirements, verifying performance specifications, integration interfaces, risk assessments and both technical and programmatic readiness. The validation confirmed that adequate margins exist for the demanding phases ahead.

Salem Butti Al Qubaisi, Director General of the UAE Space Agency, characterised the achievement as evidence of a sustainable model for national space development. By combining government investment and strategic direction with private sector expertise, the UAE is establishing an ecosystem where national companies lead complex space missions. This approach aligns with the National Space Strategy 2031, which articulates the nation’s long-term ambitions in space technology and applications.

The programme addresses two interconnected priorities for the UAE: securing reliable access to Earth observation data regardless of weather conditions, and cultivating a domestic industrial capability to provide it. By localising the assembly, integration and testing of Sirb-1’s radar payload at facilities operated by Orbitworks and the Technology Innovation Institute in the UAE, the programme builds lasting national expertise and intellectual property in a critical technology domain.

The consortium leading delivery includes FADA as prime contractor, alongside the Technology Innovation Institute, Orbitworks and other national partners. Established in 2023, this collaborative structure reflects the interconnected nature of modern space development, where government direction, academic research and commercial capability combine to achieve objectives beyond any single entity’s reach. Sirb-1 completed its Preliminary Design Review in April 2026, establishing the foundation for this month’s successful critical review.

Manufacturing and assembly now commence, with the targeted launch scheduled for 2028. This phase will demand precision at scale as engineers build the spacecraft systems and integrate the sophisticated radar payload that will make Sirb-1 operational.

What it means for Abu Dhabi

The advancement of Sirb-1 strengthens the UAE’s position in Earth observation, a field increasingly vital for environmental stewardship, agricultural efficiency and maritime awareness. The ability to monitor the nation’s natural resources, track atmospheric conditions and respond swiftly to environmental challenges becomes a matter of strategic autonomy when underpinned by sovereign satellite systems.

Beyond immediate operational benefits, the programme cultivates capabilities that extend across the national economy. Engineers and technicians gain experience in complex spacecraft systems. Companies develop expertise in advanced manufacturing and integration. Knowledge transfer across the consortium ensures that capabilities developed for Sirb-1 will enhance subsequent satellites in the planned constellation, embedding space technology expertise within the UAE’s industrial base and positioning national companies to serve regional and international markets.
