Description:

The Flock earth observing constellation built and operated by Planet Labs (formerly Cosmogia Inc.) consists of numerous triple CubeSats. The Flock-1 and Flock-1b constellations consist of each 28 satellites in medium inclination orbits. The Flock-1c constellation features 11 satellites in longer lived polar orbits.
The majority of the satellites featured a standard RGB imagging system, but five satellites were fitted with experimental systems working in different optical spectral bands.
