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.
