ICEYE X1 is a proof-of-concept prototype for a planned constellation of X-band SAR (Synthetic Aperture Radar) equipped microsatellites, designed by the Finnish ICEYE startup company.

ICEYE is designed to provide near-real-time SAR imagery. Iceye is working to launch and operate a constellation of micro satellites that carry its own compact and efficient SAR sensor technology. The ICEYE imaging radar instrument can image through clouds, obscuring weather and darkness.

The first prototype satellite, ICEYE X1, is a 70 kg satellite developed and integrated in-house by ICEYE. The satellite has a body of 70 cm in height, 60 cm in width with a deployable antenna 3.25 meters in length. The X-band SAR instrument has a resolution of 10 m.

It was launched in January 2018 as a secondary payload on a PSLV-XL. The goal of the mission is to validate in-orbit performance of the satellite and begin operations with select ICEYE customers.
