Landmapper

rdf:langString Landmapper is a remote sensing satellite constellation built and operated by (formerly known as ). It consists of two separate satellite designs: Landmapper-BC and Landmapper-HD (formerly known as Corvus-BC and Corvus-HD). These satellites will be launched into Sun synchronous orbits varying in altitude between 625 km and 475 km. Both satellites are designed to CubeSat standards: 6U XL for Landmapper-BC, and 16U for Landmapper-HD. They will be contained in deployers designed by of the Netherlands and of Germany. These deployers are to be included onboard a variety of launch vehicles, including the SpaceX Falcon 9, Rocket Lab Electron, Glavkosmos Soyuz, Antrix PSLV, and European Space Agency Vega. Each Landmapper-BC spacecraft carries three separate cameras to gather 22 meter resolution imagery in the red, green, and near-infrared spectral bands. The Landmapper-HD satellite design includes a larger telescope to gather 2.5 meter resolution imagery in blue, green, red, red edge, and near-infrared spectral bands. This imagery is processed on-board and then downlinked over a miniaturized high-speed Ka-band transmitter. The common satellite bus uses reaction wheels, magnetic torque coils, star trackers, magnetometers, sun sensors, and gyroscopes to enable precision 3-axis pointing without the use of propellant.
