Lemur-2 is a constellation of low-Earth orbiting satellites built by Spire Global. These satellites carry payloads for meteorology and ship and aircraft traffic tracking.

The Lemur-2 payload consists of three subpayloads:

  • Spire Global satellites, which orbit close to Earth's atmosphere, use the SENSE payload to listen for GPS satellite signals - which are impacted as they pass through Earth's atmosphere. Using a process called GPS radio occultation, Spire Global measures the change in GPS signal readings to calculate very precise profiles for temperature, pressure, and humidity here on Earth.
  • The STRATOS payload enables tracking ships worldwide by receiving their AIS signals.
  • The AirSafe ASD-B payload to track airplanes.
