Spire Launches New Space-Based Radio Frequency Intelligence Capabilities for Defense and Security

Written by: Leah Martin | July 28, 2025

Spire Global, a leader in space-based data and analytics, has announced a significant expansion of its Space Reconnaissance offering with the launch of enhanced radio frequency (RF) geospatial intelligence (GEOINT) capabilities. These developments position Spire as a key enabler of real-time situational awareness for government, defence, and security customers around the world.

Designed for both U.S. and international missions, the new suite of capabilities provides persistent signal monitoring, advanced geolocation services, and actionable insights derived from space-based RF data. With satellites collecting signals across VHF, UHF, and L bands, Spire is now equipped to support critical mission requirements including GNSS interference tracking, emergency beacon detection, and emitter identification.

Data is processed through Spire’s proprietary detection and geolocation engine and delivered via a secure, cloud-based platform. For customers with more stringent data sovereignty requirements, the system also supports sovereign-ready deployment, offering flexibility for national security and intelligence users.

The new tools enable users to:

  • Detect and geolocate unauthorized or unregistered RF signals across land, sea, and air;
  • Monitor emitters over time for persistent surveillance;
  • Transcribe and translate publicly broadcast voice transmissions in near real time using AI; and
  • Trigger satellite imagery to verify signal activity on the ground.

“Today’s security environment demands faster, smarter insights and that starts with knowing what’s happening on the ground in real time,” said Iain Goodridge, Senior Director of RF Geolocation Products at Spire. “With these expanded capabilities, we’re enabling customers to make confident, informed decisions even in the most challenging operational theatres.”

The announcement builds on Spire’s growing presence in the defence and intelligence domain. In 2024, the company was awarded a $14 million contract by the U.S. Air Force Research Laboratory to develop and launch a dedicated satellite cluster focused on detecting and tracking moving objects from space. Additional detection clusters are expected to deploy between late 2025 and 2026 to improve revisit rates and expand coverage across key regions.

RF geolocation has emerged as a critical tool for understanding and responding to complex, multi-domain threats. Spire’s commercial customers are already seeing operational and financial benefits, with one defence intelligence partner noting that Spire’s services have enabled them to reduce reliance on terrestrial and aerial assets, saving millions of dollars.
