Description:

Lemur-2 is the initial constellation of low-Earth orbiting satellites built by Spire. These satellites carry two payloads for meteorology and ship traffic tracking.
The Lemur-2 satellites carry two payloads: STRATOS GPS radio occultation payload and the SENSE AIS payload.
The SENSE payload enables tracking ships worldwide by receiving their AIS signals. Spire satellites, which orbit close to Earth's atmosphere, listen for GPS satellite signals - which are impacted as they pass through Earth's atmosphere. Using a process called GPS radio occultation, Spire measures the change in GPS signal readings to calculate very precise profiles for temperature, pressure, and humidity here on Earth.
