Finnish space technology firm ICEYE has handed over a four-satellite synthetic aperture radar (SAR) reconnaissance constellation to the Polish armed forces, less than 12 months after contract signature. The company has described this as the fastest operational deployment of a satellite program on record.
The system, built under the MikroSAR program and operationally designated POLSARIS (Polish SAR Intelligence System), was transferred to Poland’s Geospatial Reconnaissance and Satellite Services Agency (ARGUS) on May 15, 2026. The contract with Poland’s Ministry of National Defense, worth approximately €200 million, was signed in May 2025.
ICEYE acted as consortium leader, delivering the satellites and space segment, while Wojskowe Zakłady Łączności Nr 1, part of the Polish Armaments Group (PGZ), supplied the ground segment and mobile infrastructure.
Four-satellite constellation
ICEYE has built and launched four SAR satellites over the course of the contract. The baseline scope, consisting of three satellites, was delivered within 10 months of signature, with the first contract option, adding a fourth satellite, being activated a month later. Polish military operators have been trained to run the constellation independently, the company said.
Each satellite carries an X-band SAR sensor capable of imagery at resolutions as fine as 25cm, with operating modes ranging from wide-area surveillance suited to border and maritime monitoring to high-precision targeted collection. Like all SAR systems, the constellation can image through cloud cover and at night, an attribute that has proved central to Ukrainian battlefield intelligence since 2022.
Growing European ecosystem
“Reaching operational readiness within one year of contract signing sets a new global benchmark,” Rafał Modrzewski, ICEYE’s CEO and co-founder said in a statement. He framed the program as proof “that ambitious space programs can be delivered on our own terms, to our own standards, and at the right pace”.
Polish Deputy Prime Minister and Minister of National Defense Władysław Kosiniak-Kamysz described the handover as a step in developing Poland’s “modern intelligence-gathering capabilities,” calling satellite Earth observation “a tool of strategic importance” for the country’s military.
ARGUS, established by the Ministry of National Defense in 2024, is now the constellation’s sole operator. The POLSARIS name was selected through an open competition organized by the agency in late 2025. The jury cited both its acronymic clarity and its nod to Stanisław Lem’s novel Solaris.
The acquisition is among the most visible European national SAR procurement efforts since the start of Russia’s full-scale invasion of Ukraine, alongside parallel sovereign-imagery efforts pursued by France, Germany and Italy.
