BRINGING RF ISR-T TO
SMALL UAS IN DENIED ENVIRONMENTS
The power of RF ISR-T, miniaturized for the tactical edge.
Applied Signals Intelligence (ASI) delivers advanced Radio Frequency (RF) Direction Finding (DF) and geolocation sensors that enable autonomous Electromagnetic Spectrum Operations (EMSO) from Group 2 Unmanned Aerial Systems (UAS) and other low-SWaP platforms.
In contested, GPS-denied, and communication-challenged environments, ASI empowers you to know the unknown — detecting, and targeting RF threats from a single platform without mission crews or external coordination.

Compact EMSO Solutions for the Modern Battlespace
Traditional RF ISR relies on either multi-aircraft architectures that demand GPS synchronized platforms, coordinated maneuvering, and real-time datalinks, or on large, specialized ISR aircraft that deliver precision DF but are high-value, poorly suited for contested environments, and too few to provide coverage when and where needed. ASI redefines EMSO with ultrawideband (UWB), passive RF sensors that provide real-time situational awareness without large airframes, antenna baselines, multiple aircraft or GPS.
Key Capabilities of ASI’s RF Sensing Solutions
Ultrawideband RF DF & Geolocation
Ultrawideband RF DF & Geolocation
Operate across HF to 18 GHz for detection and tracking of communications signals, jammers, counter-battery radars, air defense radars, and agile/frequency-hopping waveforms in real time.
Single-Platform Wide Field of View (FOV) 3D DF
Single-Platform Wide Field of View (FOV) 3D DF
Eliminate the need for multi-aircraft FDOA/TDOA architectures or large ISR platforms.
ASI’s passive sensors deliver full 360° azimuth and up to 180° elevation DF from a single small platform, enabling precision geolocation in denied environments.
Low Size Weight and Power (SWaP) Tactical Sensors
Low Size Weight and Power (SWaP) Tactical Sensors
Operating from HF to 18 GHz, ASI’s sensors are compact enough to fit in a 6-inch diameter x 7-inch long volume, weighing as little as 3.5 lbs. and operating at 40 Watts.
Enables deployment on Group 2 UAS, Launched Effects (LE), High-Altitude Balloons (HAB), Tethered UAS (TeUAS), one-way UAS, ground vehicles, and maritime vessels.
Platform Agnostic Integration with MOSA Interfaces
Platform Agnostic Integration with MOSA Interfaces
ASI’s sensors implement a modular design for rapid integration using Modular Open Systems Approach (MOSA) standards with open form, fit, and function mechanical, electrical, and logical data to simplify deployment across diverse platforms.
No GPS Required for DF and Geolocation
No GPS Required for DF and Geolocation
ASI sensors do not depend on GPS synchronization or timing to track and localize RF emitters.
This enables RF targeting in contested, degraded, denied environments, with high-latency, low-bandwidth operational conditions.
SNITCH™
SNITCH is ASI’s field-proven ultrawideband RF sensor for tactical DF and geolocation missions.
Rivet Joint in the Palm of Your Hand
SNITCH delivers single-ball / single platform, precision RF 3D DF and targeting of much larger platforms on Small UAS. Supports COMINT, SIGINT, and ELINT modalities.
Low SWaP
Complete payload fits in 6”D x 7”L cylinder, total weight 3.5 lbs., average power consumption of 40 Watts
Ultrawideband
HF to 18 GHz frequency coverage, 200 MHz instantaneous bandwidth (IBW)
GPS Denied
Single platform RF ISR-T solution. No GPS or communications required for DF/GEO
Wide FOV
Passive 360° Azimuth and 90+° Elevation Field of View (FOV) with no moving parts
Launched Effects (LE)
6-inch diameter tube-launched, scissor-wing UAS for stand-in sensing and targeting
Long Endurance Medium Altitude UAS
Solar-powered Group 2 UAS providing persistent standoff RF ISR-T
High Altitude Balloons (HAB)
Stratosphere proven on super-pressure and zero-pressure platforms for wide area of regard RF ISR-T.
Tethered UAS (TeUAS)
Mast-replacement and Just-in-Time Tower ISR-T capability for expanded area coverage and enhanced RF visibility above tree canopies, terrain masking, and urban obstructions.
Provides persistent overwatch and RF DF from elevated vantage points without the need for permanent infrastructure.
One-Way UAS with Home-on-Jam / Home-on-Threat
Expendable UAVs acting as autonomous RF-seekers to strike active jammers and radars.
Turboprop Manned Aircraft
Rapid-fit sensor configurations for crewed ISR platforms requiring lightweight, passive RF geolocation capability.
Delivers HF to 18 GHz coverage using a single compact antenna, eliminating the need for up to 21 external antenna mounts typically required for similar wideband operation.
Avoid invasive airframe modifications to preserve aircraft aesthetics, resale value, and flight performance, while achieving full RF ISR functionality with minimal installation complexity.
Applications for Tactical EMSO and ISR-T
ASI’s sensors enable next-generation EMSO for survivable, distributed, and autonomous operations in denied environments.
