Lemur-2 (Low Earth Multi-Use Receiver) satellites are 3-Unit CubeSats built and operated by the American company Spire Global. These small satellites are used to track maritime, aviation, and weather activity from space equipped with AIS, ADS-B and GNSS-RO sensors. Each Lemur-2 satellite measures 10x10x34,5 cm, weighs less than 6 kg and is powered by a deployable solar array. Most of the Lemur-2 satellites are deployed into low-Earth orbit in small batches from the International Space Station (ISS) or from commercial launch vehicles such as Falcon 9 or Electron rockets. Spire Global is a space-to-cloud data and analytics company that specializes in the tracking of global data sets powered by a large constellation of nanosatellites, such as the tracking of maritime, aviation and weather patterns. Lemur-2 data is highly valuable for public and private weather forecasters across the world and is also is valuable for use in illegal fishing, trade monitoring, maritime domain awareness, insurance, asset tracking and search and rescue.
