Planet Labs, Inc. (formerly Cosmogia, Inc.) is an American private Earth imaging company based in San Francisco, CA. Their goal is to image the entirety of the Earth daily to monitor changes and pinpoint trends. The company designs and manufactures Triple-CubeSat miniature satellites called Doves that are then delivered into orbit as secondary payloads on other rocket launch missions.
Each Dove is equipped with a high-powered telescope and camera programmed to capture different swaths of Earth. Each Dove Earth observation satellite continuously scans Earth, sending data once it passes over a ground station.
This is accomplished through a technique called a line scan, which allows for continuous, high resolution imagery due to the fact that this type of camera is not restricted to specific vertical resolution.
