Abstract text The BlackSky constellation, owned and operated by the US company BlackSky Inc. (NYSE: BSKY), whose data is distributed by Telespazio/e-GEOS in Europe and world-wide thanks to an agreement signed on 2018, is a new EO very high resolution optical (VHRO) mission designed with the goal of providing the highest daily revisit on the market at about 1mt resolution.
Currently the system is composed by eight satellites, launched since 2019; the two newest satellites, launched on November 18th, 2021, reached orbit and delivered first images within 14 hours of launch. The constellation is growing fast: additional two/four satellites are planned for launch within end of 2021, to be followed by other satellites of the same class (less than 60 kg mass) by mid 2022. The next achievement of a baseline of at least 16 operational satellites will allow a revisit of more than 8 acquisitions every day.
The orbital configurations of the constellation (including polar and inclined orbits) allows to achieve multiple acquisitions every day, during all daylight hours, with on-demand satellite tasking and fast access to the constellation available at multiple priority levels, granting a unique “First-to-know” advantage.
The imaging performance is based on a framing camera with color filter array that, in its latest version (thanks also to the position to a lower orbit), provides a sub-metric resolution over a n about 25 Km2 area.
The BlackSky image quality is monitored and calibrated continuously, as soon as new satellites become available, using specific calibration targets. e-GEOS will present some of its internal analysis on the images, as well as examples of operation tests that have already demonstrated a very short tasking lead-time and fast delivery timelines.
