Summary
FLOCK 4S-11 is a CubeSat (3U) satellite owned by PLAN and manufactured in the US. Launched on January 24, 2021, from Launch Pad LC40 at AFETR using a Falcon 9 launch vehicle, it has dimensions of 0.3 meters length and diameter with a span of 0.3 meters. The satellite weighs 5.7 kilograms dry and is equipped with solar cells for power generation along with batteries. It carries an imaging payload designated as Dove 2445, specifically designed for PS0, PS1 or PS2 imaging purposes. Its mission focuses on technology applications, and it is expected to operate in a lifespan of approximately one year when placed in the International Space Station orbit or two to three years in sun-synchronous orbit (SSO). The satellite has a box shape with two panel extensions and no motor except for those designated as FEEP (#Flock-3p').
