Rioâ„¢ Signals Intelligence System

Rio SIGINT capabilities meet rigorous mission requirements for small, manned and unmanned intelligence, surveillance and reconnaissance (ISR) platforms. Rio intercepts, locates, monitors and records communications signals using a common set of software applications.  

Rioâ„¢ Signals Intelligence System

Features

  • 12 or 16 coherent receiver channels for simultaneous search, detect, copy, special signals and N-channel DF/beam forming
  • Supports third-party plugins for special signal processing
  • Member of L3Harris scalable COMINT family — common software and future upgrades
  • Open C2 interface
  • Remote or local operators using as little as 100 Kbps of IP datalink
  • High-resolution maps for situational awareness display signal locations and Rio/aircraft tracks
  • Operates in a non-pressurized environment
  • Real-time audio and digitized RF recording and playback for later analysis
  • Supports up to 30 operators
  • Uses omni-directional antenna arrays for collection and geolocation
  • Joint Interface Control Document (JICD) compliant; interoperable with Theater Net-Centric Geolocation (TNG) networks for multi-platform precision geolocation
  • Network Centric Collaborative Targeting (NCCT) interface

Applications

  • Wartime and peacekeeping tasks
  • Monitoring and geolocation of target communications
  • Cue imagery sensors for visual identification
  • Customizable cues for other sensor types

Rio Innovation & Way Forward

  • Rio is a TRL 9 product that has been exported to multiple countries
  • Rio Nino can provide a significant SIGINT capability to many SWaP-challenged small manned and unmanned platforms
  • Rio Grande provides additional compute and tuner resources to support more simultaneity, more operators, more missions
  • The Rio software suite can be configured and scaled as needed
  • All Rio software is unclassified and developed using Research and Development funds
  • Development and integration of new capabilities is continuous
  • Rio has an approved software licensing and product pricing structure
