ICEYE, the global leader in persistent monitoring and natural catastrophe solutions, successfully launched three additional synthetic aperture radar (SAR) satellites on March 4, 2024, including a 1200 MHz radar bandwidth in-orbit technology demonstrator that will enable 25 cm imaging. The satellites were integrated via launch integrator Exolaunch and successfully lifted off aboard SpaceX’s Transporter-10 rideshare from Vandenberg Space Force Base in California, USA. Each spacecraft has established communication, and early routine operations are underway.

Two of the three SAR satellites launched on the mission are manufactured by ICEYE US, while one is an in-orbit technology demonstrator manufactured by ICEYE in Finland. The in-orbit demonstrator model features an upgrade to ICEYE’s unique X-band antenna, increasing radar bandwidth to 1200 MHz. This enables higher-resolution imagery, up to 25 cm, and will be initially assigned to engineering tests before being made available to ICEYE customers.

“Our growing constellation provides an objective and reliable source of intelligence, enabling a faster, more accurate response to changes taking place anywhere on the planet,” Rafal Modrzewski, CEO and Co-founder of ICEYE. “The launch of the 1200 MHz bandwidth technology demonstrator delivers 25 cm resolution SAR imaging, unlocking a new level of clarity and detail for high-priority decision-making.”

The satellites launched include an advanced radar that enables major improvements in image quality, faster downlink speeds for more agile imagery collections, and better integration with ICEYE’s global network of ground stations.

Eric Jensen, CEO of ICEYE US, said: “Our partners require dependable and persistent change detection to address emergent, time-critical needs. We are proud to add two additional U.S-built satellites to our constellation, strengthening our commitment to deliver strategic insights for our defense, intelligence, civil, and commercial customers.”

ICEYE has now successfully deployed 34 spacecraft since 2018 and operates the world’s largest constellation of SAR satellites, which can image any location on the Earth’s surface in any environmental condition, day or night. SAR data provides precise insights for ICEYE’s government and commercial customers in near real-time.

ICEYE plans to launch up to 15 satellites in 2024.
