In order to address market demand for higher resolution and faster revisit of EROS satellites, ImageSat has launched the EROS B satellite.

Slightly larger and similar in appearance to EROS A, the new satellite has superior capabilities, including a larger camera of CCD/TDI type (Charge Coupled Device/Time Delay Integration), with standard panchromatic resolution of 0.70 m at an altitude of about 480 km, a larger on-board recorder, improved pointing accuracy and a faster data communication link.

The expected lifespan of the EROS B is ten years.

EROS B1 will fly in a 480 km (259 nmi), circular, sun synchronous orbit at 97.33 degrees.

EROS B1 will be the second launch for an 8 satellite constellation owned and operated by ImageSat International.

The satellite will be built by Israel Aircraft Industries. The EROS B satellites are expected to have at least a 10 year life. When six satellites are in space, imaging will be possible at least once a day for any specific site within the coverage area of a Ground Receiving Station, and eight satellites will allow revisitation more than twice daily.
