The EROS C3 satellite was built by Israel Aerospace Industries and is based on IAI’s Optsat 3000 satellite platform with a launch mass of about 880 pounds, or 400 kilograms. ImageSat International, or ISI, signed a contract with IAI to construct the EROS C3 satellite in December 2017.

In financial statements, ISI describes EROS C3 as an Optsat 3000-class satellite with “very-very high resolution and multi spectral capabilities.”

ISI says its constellation includes two other EROS C-class satellites, EROS C1 and EROS C2, already in orbit. Those two satellites were “commercialized” by ISI in 2021, after launch by a separate operator, possibly as part of the the Israeli government’s Ofeq spy satellite fleet, or by another Israeli company. ISI said in a financial prospectus earlier this year that EROS C1 and EROS C2 are owned by a third party, but ISI has exclusive access to commercial imagery from the satellites

EROS C3 will join ISI’s fleet as a commercially operated satellite from the start, but the high-resolution pictures from the spacecraft will likely be used by ISI’s military and government customers, which include a nexus of Israeli clients and others around the world.

ISI says EROS C3 has similar imaging capabilities as EROS C1 and EROS C2. The company eventually plans to operate a fleet of six “military-grade” imaging satellites, called the EROS NG constellation, with EROS C-class electro-optical and EROSAR synthetic aperture radar capabilities.

“EROS C serves as the backbone of the EROS NG constellation,” ISI says on its website. “Through ISI’s advanced ground control segment, it enables defense and intelligence organizations to conduct operations under complete confidentiality and data protection, as well as independent mission execution, with no preemption/shutter control.”

ISI said earlier this year it planned to enter into a contract to build another electro-optical satellite, EROS C4, for launch in 2026.
