Lemur 1, for Earth-observation in the visible band and in infrared, was the prototype for a constellation of more than 50 Lemur 2 CubeSats. The constellation of over 60 CubeSats, the largest general purpose cubesat constellation, is devoted to weather forecast and to track ship and airplanes traffic. The Lemurs (Low Earth Multi-Use Receiver) by Spire Global are equiped with GPS radio occultation (for Earth atmosphere monitoring), maritime AIS (Automated Identification System) and aviation ADS-B (Automatic Dependent Surveillance-Broadcast) payloads. Launching and replacing satellites often consistently increases the capability and services of the constellation.
