On-orbit demonstration successfully identifies and geolocates S- and X-band radio frequency signal sources

Spire Global, Inc. (NYSE:SPIR) ("Spire" or "the Company"), a global provider of space-based data, analytics and intelligence, has successfully demonstrated single-satellite radio frequency (RF) geolocation techniques on orbit, including the detection and geolocation of S-band and X-band radio frequency signals.

Traditionally, RF geolocation relies on multiple satellites operating together to determine the origin of a signal. Spire's single-satellite RF geolocation capability expands the company's RF sensing capabilities by enabling the identification and geolocation of higher-frequency emitters, including S- and X-band signals, using sensors onboard a single satellite.

The satellite launched in late 2025 aboard SpaceX's Bandwagon-4 mission and was co-funded by the Government of Luxembourg through an ESA Contract in the Luxembourg National Space Programme, LuxIMPULSE, managed by the Luxembourg Space Agency.
