Planet Labs – Wikipedia

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 planet 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. Together, Doves form the largest satellite constellation in the world that provides a complete image of Earth once per day at 3–5 m optical resolution. 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.

The images gathered by Doves, which can be accessed online and some of which is available under an open data access policy, provide up-to-date information relevant to climate monitoring, crop yield prediction, urban planning, and disaster response. With acquisition of BlackBridge in July 2015, Planet Labs had 87 Dove and 5 RapidEye satellites launched into orbit. In 2017, Planet launched an additional 88 Dove satellites, and Google sold its subsidiary Terra Bella and its SkySat satellite constellation to Planet Labs. The combined batches of Doves form the largest constellation ever put into orbit. By September 2018 the company had launched nearly 300 satellites, 150 of which are active.
