Flock :The flock consists of multiple satellite constellations which are designed to observe Earth. By using several small satellites, CubeSats, the constellation produces three to five meters high resolution images of Earth. Flock/PS3p :Flock 3p, consisting of 88 Dove satellites, were launched from Satish Dhawan Space Centre in Sriharikota, India, by ISRO (Indian Space Research Organization) PSLV-C37 on 15 February 2017.id:Flock/PS3p.a |
