teamSENTINEL: Visualizing the RF spectrum

Espy teamSENTINEL Highly scalable, streaming wideband recording, direction finding (DF) sensors:

The teamSENTINEL family of radio frequency collection, and DF-enabled sensors are optimized for extended recording and  acquisition bandwidth. They provide simultaneous monitoring, analysis, and recording of time and frequency coherent, wideband RF spectrum, through Espy’s teamSOIGNE® signal-mining GUIs.  

Frequency band coverage of each sensor is determined by the RF Conditioner module selected. Options exists to support HF, HF/DF, V/UHF, and V/UHF-DF operations, as well as Dual-band operations (HF and V/UHF concurrently). All teamSENTINEL sensors are QuickAssist-AI/ML signal classification enabled and Theater Net-Centric Geolocation (TNG) node compliant when configured and operated with the necessary GPS-disciplined references. 

Special Features

• Collect and store up to 50 days of wideband RF energy for retroactive signal processing (including DF) and analysis.
• QuickAssist – Artificial Intelligence / Machine Learning (AI/ML) Automated Signal Detection and Categorization.
• Theater Network-Centric Geolocation (TNG) compliant time and frequency operations.
• Options for frequency coverage from as low as 10 kHz up to 6 GHz currently available.  
• Recorded stare bandwidths from 11 MHz to > 1 GHz with support for multiple independently tunable stare elements. 

Sensor Modules

The teamSENTINEL family of wideband sensors are modular, flexible, and highly scalable, providing a very cost-effective platform that can be easily adapted to support a wide range of mission requirements. TeamSENTINEL subsystems are built using a combination of industry leading COTS solutions, and Espy developed hardware and software solutions.  

RF Conditioner

This module utilizes COTS software defined radio (SDR) while applying bandpass filtering and attenuation as necessary, prior to digitization and stream digital IF out via 10GigE ports formatted in Vita49 standard. HF, V/UHF, and Dual-band sensors are available in both DF and non-DF configurations. All RF Conditioner modules incorporate a GPS subsystem to provide built-in, TNG-compliant, system operations for most mission.  requirements (this subsystem can be bypassed if an external GPS-disciplined reference is mandated). Multiple RF Conditioner modules can be ganged together to increase a sensors acquisition bandwidth.

RF Distribution Modules

Espy designs and builds a family of commutative DF sequencer modules, RF multicouplers, and RF band switches, to address the stringent operational and performance requirements of our wideband HF and V/UHF capabilities. One or more DF Sequencer modules can be configured to support a wide range of Espy-designed and 3rd party DF antenna configurations. DF Sequencers are time coherent with receivers, to guarantee maximum angle-of-arrival DF stare bandwidths from 11 MHz to > 1 GHz with support for multiple independently tunable stare elements.
