PS2  

Definition

  • Planet achieved Mission 1 after the successful launch of 88 Dove satellites in February 2017 and the successful launch of a further 48 Dove satellites in July 2017. This groundbreaking feat enabled Planet to image the world’s land mass, roughly 150Mkm2, every single day in 4 spectral bands: blue, green, red and near-infrared (NIR). These Dove satellites carry instruments comprised of a telescope we call "PS2" paired with a 2D frame detector having 6600 pixels across by 4400 lines down. The detector has a Bayer pattern filter separating the wavelengths of light into blue, green and red channels. On top of the Bayer pattern filter is a “2-stripe” filter, where the top half blocks the NIR wavelengths, thus allowing only the blue, green and red light to pass through, and the bottom half allows only the NIR wavelengths of light to pass through.
