These Doves aren't the first of their kind to be sent into orbit, or even the 14th. Planet already has a flock of 50 such miniaturized probes up there. But with these additional 88, Planet can claim the distinction of having "the biggest fleet of Earth-imaging satellites — and of satellites in general — in human history," a company rep told The Verge.
Now that the diminutive, 4-inch by 12-inch satellites have reached space, they'll enter into a Sun-synchronous orbit, which will have them circling the poles. This allows the flock to cover the same part of the planet every day at the same time, which in turn allows the company to collect standardized, predictable imaging of the Earth's surface. This won't happen immediately, however, as the company will next need to spend a couple months properly positioning each probe in its assigned orbit.
