Ngu industries early access6/12/2023 ![]() of Espoo, Finland developed and built the ICEYE-X2 spacecraft with a SAR (Synthetic Aperture Radar) instrument suitable for a microsatellite. The commercial Earth Observation (EO) company ICEYE Ltd. ![]() ICEYE Constellation of SAR X-band microsatellites Spacecraft and sensor complement Launches Mission Status References ICEYE provides Level 1, 1a and 1b data products, that is, they can either be complex images which have both amplitude and phase values, or amplitude images which have amplitude-only pixels. The ICEYE satellites are able to downlink data to the ground for processing at 140 Mbit/s in the X-band range. Space and Hardware ComponentsĮach ICEYE spacecraft has a mass of 85 kg, with X-band sensors utilising active phase array antennas that are electronically steerable, allowing the satellites the ability to look both left and right, with a range bandwidth between 40-300 MHz. The ICEYE satellites are in sun-synchronous orbit at an inclination of 97.7° with an orbital frequency around 96 minutes. When all 48 satellites are in orbit, this will enable twice daily revisit time over locations on Earth. Scan imagining mode is a wide area imaging mode able to create a scene size of 100km x 100 km, with a ground resolution of 15m x 15 m at incidence angles of 21-29°.Įach satellite in the ICEYE constellation has a ground track repeat time of 17 day, with 21 satellites currently in orbit, this allows ICEYE to have daily coherent ground track repeat. Strip mode enables imaging of any area on Earth with spatial resolution of 3 m and scene size of 30 km x 50 km it has a ground resolution of 3.0m x 3.0 m, and slant resolution of 0.5-2.5 m x 3.0 m at incidence angles of 15-30°. SLEA mode provides the largest very-high resolution SAR imagery with ground resolution of 1.0m x 1.0m and a scene size of 15 km x 15 km, or slant resolution of 0.5m x 1.0 m at incidence angles of 20-35°. Spot mode offers the finest resolution available with a ground resolution of 1.0 m x 1.0m, and it is able to image a scene of size 5km x 5km at incidence angles of 20-35°. Spot extended area (SLEA) imaging mode,.ICEYE images in 4 distinct imaging modes: ICEYE data is used in a variety of industries, including insurance, financial, energy, utilities, mining, civil, maritime and security. ICEYE’s ability to persistently monitor locations is critical in order to detect high-frequency change and respond to real events that require a lot of decision-making examples of this include natural disasters such as floods, vessel monitoring, and oil spill monitoring. ICEYE uses the X-band frequency of 9.75 GHz at a wavelength of around 3 cm, and has a pulse rate frequency of 2-10 kHz. ![]() Each satellite of the ICEYE constellation carries an X-band Synthetic Aperture Radar (SAR), allowing the instruments to “see” through darkness, clouds and rain to observe Earth at all times. ![]()
