Technical Note on Quality Assessment for ICEYE X4, X6 & X7
Year: 2025
Type: article
Abstract: The ICEYE constellation is formed by several small satellites, each one weighing less than 100 kg. The large constellation is aimed to enable imaging of specified areas of interest multiple times a day, thus allowing quick tactical acquisitions as well as frequent revisit rates globally. The first proof-of-concept platform (ICEYE-X1) was launched in January 2018 followed by a second satellite (ICEYE-X2) in December 2018. Recent deployments include launches of X6 and X7 in September 2020; X8, X9, X10 in January 2021; X11, X12, X13 and X15 in June 2021; X14 and X16 in January 2022; X17, X18, X19; X20 and X24 in May 2022. Commercial access to ICEYE 1-m resolution SAR imagery began in October 2019. The current operational plan foresees a constellation of 18 satellites operating at X-band. ICEYE can be operated in Spotlight (<1 m resolution, up to 10 km swath), Stripmap (3 m resolution, 30 km swath) and ScanSAR (15 m resolution, 100 km swath) modes. Spot and Stripmap images can also be used for SAR interferometry. The TN covers the X4,6,7 satellites data assessment.
