Spire Global Successfully Demonstrates Single-Satellite RF Geolocation Techniques
Spire Global has successfully demonstrated single-satellite radio frequency 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.
