Planet shares information on Tanager hyperspectral constellation

PARIS – Planet launched further details about the hyperspectral constellation the Earth-observation firm is creating by the Carbon Mapper public-private partnership.

San Francisco-based Planet stays on schedule to launch the primary two hyperspectral satellites in 2023 to collect knowledge in 400 spectral bands with a decision of 30 meters per pixel.

Whereas knowledge to pinpoint methane and carbon dioxide sources can be shared publicly by the Carbon Mapper Coalition, Planet additionally will mix hyperspectral knowledge with electro-optical imagery obtained by its Dove, Pelican and SkySat satellite tv for pc fleets to offer knowledge and insights for presidency and industrial prospects.

“By serving to to determine the spectral ‘signatures’ of chemical substances, supplies and processes throughout the globe, hyperspectral knowledge can reveal in any other case hidden tendencies and will fill intelligence gaps and mitigate dangers,” in accordance with a Sept. 19 information launch.

Planet’s hyperspectral satellites destined for sun-synchronous orbit are known as Tanager, named for a household of colourful Central and South American birds.

In 2021, a consortium led by the State of California, NASA Jet Propulsion Laboratory and Planet introduced plans for the Carbon Mapper constellation of satellites geared up with hyperspectral sensors to detect, quantify and monitor sources of methane and carbon dioxide. Extra Carbon Mapper Coalition companions embrace the College of Arizona, Arizona State College, the Excessive Tide Basis and the non-profit RMI.

“Past providing methane and CO2 signatures, Planet’s industrial hyperspectral providing appears to be like to offer prospects with knowledge for dozens of different environmental functions and indicators which might be wanted to carefully monitor the well being of the planet,” in accordance with the information launch. “The satellites’ hyperspectral sensor expertise, pioneered by NASA Jet Propulsion Laboratory will present 30-meter decision and a full spectral vary of shortwave infrared and high-precision 5-nanometer extensive bands; this hyperspectral providing is designed to assist organizations perceive adjustments on land and at sea, from coastal zones to forests to city areas and extra.”

Planet obtains day by day imagery of Earth’s landmass with a constellation of greater than 200 satellites.

Tanager satellites are being manufactured in San Francisco, alongside Doves and Pelicans.

Planet is upgrading its constellation of Dove cubesats with SuperDoves, which collect imagery in eight spectral bands at a decision of about 3 meters per pixel, in contrast with 4 spectral bands for his or her predecessors.

The corporate continues to acquire high-resolution imagery from SkySats, manufactured by Maxar Applied sciences.
