CSDA Vendor – ImageSat
ImageSat operates a constellation of four optical satellites: EROS‑C2, EROS‑C3, EROS‑B, and Runner. The EROS‑C pair forms the backbone of the constellation, providing consistent, near‑global measurements. These two satellites fly in mid‑inclination low Earth orbit and carry very high‑resolution optical payloads, enabling daily revisits and uniform radiometry and geometry for global change…
