Spire Global Subsidiary, Inc., (Spire) designs, builds, and operates a growing constellation of over 120 3U Low Earth Multi-Use Receiver (LEMUR) satellites designed to collect radio frequency (RF) signals from Low Earth Orbit (LEO). The company offers a suite of commercial RF sensing products, including a catalog of atmosphere, ionosphere, and weather data services derived from Global Navigation Satellite System (GNSS) signals collection.
The LEMUR satellites are equipped with the STRATOS payload, which collects GNSS signals from which Spire can derive a range of Earth observation data for climate and space weather research, among other applications.
Spire was one of the companies selected for evaluation in the original CSDA Pilot and since then has provided new products that have gone under evaluation and are now available.
All members of the U.S. Government have access to Spire data for scientific use. All data requests must be approved by CSDA.
