The UAE has reached another milestone by successfully launching Etihad-SAT on March 15. The high-precision observational satellite lifted off aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, California. This marks the nation’s second satellite launch in just three months.
At the Mohammed bin Rashid Space Centre (MBRSC), scientists celebrated as Etihad-SAT, the country’s first Synthetic Aperture Radar (SAR) satellite, entered orbit via SpaceX. This achievement strengthens the UAE’s growing role in the global space industry.
Why is UAE Etihad-SAT unique?
Etihad-SAT captures high-resolution images 24/7, regardless of weather or time. Rain, fog, or darkness won’t affect its performance.
– Disaster response – Helps monitor and manage natural disasters effectively.
– Oil spill detection – Supports efforts to control environmental damage.
– Navigation and agriculture – Aids maritime navigation and farming industries.
How does it work?
Etihad-SAT continuously sends radar waves toward Earth. These waves bounce off surfaces, reflecting differently based on material properties. This enables real-time, detailed imaging in all conditions.
Weighing 220kg, the satellite orbits at 500 km above Earth. The data is processed using artificial intelligence, producing high-resolution images for analysis.
SAR vs. optical satellites – key differences
The UAE has launched both optical and SAR satellites. Here’s how they compare:
– Optical satellites use sunlight reflections to capture images.
– SAR satellites send electromagnetic radar waves, reflecting off surfaces for clear imaging day or night.
– SAR satellites provide detailed mapping, crucial for environmental monitoring and security applications.
How Etihad-SAT scans the Earth
The satellite features three imaging modes, each designed for specific applications:
- Spot mode – Captures small areas with high-resolution imaging.
- Scan mode – Provides a wider area view for broad analysis.
- Strip mode – Covers longer land stretches for extended monitoring.
Strengthening the UAE space vision
With Etihad-SAT’s success, the UAE reaffirms its commitment to space innovation. Investing in advanced SAR technology, the nation enhances its expertise in earth observation, disaster management, and environmental protection.
This mission marks another step forward in UAE’s space journey, paving the way for more groundbreaking advancements in satellite technology and research.
