The EROS\u2011C pair forms the backbone of the constellation, providing consistent, near\u2011global measurements. These two satellites fly in mid\u2011inclination low Earth orbit and carry very high\u2011resolution optical payloads, enabling daily revisits and uniform radiometry and geometry for global change detection. Their instruments collect very high\u2011resolution panchromatic and multispectral imagery, along with standard mono and stereo acquisition modes to support time\u2011series analysis.<\/p>\n<p class=\"wp-block-paragraph\">In addition to the EROS-C pair, EROS-B, the constellation\u2019s heritage platform, has collected high-resolution optical data that provides a valuable dataset for researchers investigating long-term environmental change. Lastly, Runner (launched in 2023) augments the constellation, enhancing observational frequency while maintaining data quality.<\/p>\n<h2 class=\"wp-block-heading\">Obtaining Data<\/h2>\n<p class=\"wp-block-paragraph\">All newly awarded commercial data provider products are currently undergoing CSDA evaluation.
