CSDA Vendor - Spire
NASA's Commercial Satellite Data Acquisition (CSDA) program has acquired commercial datasets from Spire for scientific purposes.
Spire Global Subsidiary, Inc., (Spire) designs, builds, and operates a growing constellation of over 100 3U Low Earth Multi-Use Receiver (LEMUR) small 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 collections of Global Navigation Satellite System (GNSS) signals.
Spire 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.
