Spire Global Achieves Single-Satellite RF Geolocation Breakthrough

Event summary

  • Spire Global demonstrated single-satellite RF geolocation of S-band and X-band signals, traditionally requiring multiple satellites.
  • The capability was achieved using a satellite launched in late 2025 aboard SpaceX’s Bandwagon-4 mission.
  • The project was co-funded by the Government of Luxembourg through an ESA Contract in the Luxembourg National Space Programme, LuxIMPULSE.
  • Spire's RF geolocation capabilities now span multiple bands including VHF, UHF, GNSS L-band, S-band, and X-band.

The big picture

Spire Global's breakthrough in single-satellite RF geolocation enhances its ability to provide critical signal intelligence for defense and national security missions. This capability expands the range of detectable signals, improving efficiency and potentially opening new market opportunities in an increasingly competitive space-based data industry.
