UAE: SIRB LEO satellite passes Critical Design Review 10/11/2026 | Pietro Batacchi

The Emirati SIRB satellite has passed its Critical Design Review (CDR) in recent weeks and is on track for launch in 2028.

SIRB is a Low Earth Orbit (LEO) satellite fitted with a Synthetic Aperture Radar (SAR). Its development is coordinated and funded by the UAE Space Agency as part of a program to build a next-generation SAR constellation in LEO for Earth observation.

SIRB is the result of a partnership between FADA, an EDGE Group company and the program’s prime contractor; Italy’s MetaSensing, which supplies the radar payload; and Singapore’s ST Engineering, which provides the satellite platform.

The current contract covers the delivery of 1 satellite, the first of the 3 planned under the program roadmap.

The goal is to give the UAE an independent, high-resolution monitoring capability over its national territory, with particular attention to its borders and critical infrastructure.
