RF Sentinel provides unified passive monitoring of aircraft, ships, drones, weather balloons, and amateur radio on a single real-time map. Stream directly to ATAK/WinTAK for complete situational awareness.
RF Sentinel monitors multiple RF bands simultaneously, displaying all detected signals on a single real-time map interface.
1090 MHz / 978 MHz (UAT)
Monitor commercial and general aviation aircraft broadcasting ADS-B transponder signals. See callsigns, altitudes, speeds, and flight paths in real-time.
161.975 / 162.025 MHz
Track ships, boats, and maritime vessels broadcasting AIS position reports. Ideal for coastal properties and waterfront monitoring.
2.4 GHz + 5 GHz WiFi / BLE
Receive FAA-mandated Remote ID broadcasts from compliant drones including DJI and Skydio. Dual-band WiFi 6 receiver captures all broadcast frequencies.
5.8 GHz / 2.4 GHz / 915 MHz
Multi-band detection of FPV video, control links, and telemetry. Identifies racing drones, long-range systems, and aircraft that may not broadcast Remote ID.
SondeHub API
Track radiosondes and weather balloons in your area via SondeHub. Monitor NWS balloon launches and descending equipment for potential recovery.
144.390 MHz
Monitor amateur radio APRS position reports. Track ham radio operators, mobile stations, and APRS-equipped assets in your region.
RF Sentinel is designed for 24/7 unattended operation with a modern web interface accessible from any device on your network.
Interactive Leaflet-based map with multiple tile layers, track history trails, and clustering.
SQLite database stores all detections locally. Query historical data and analyze patterns.
Automatically correlate multiple signal types from the same target. Pro feature.
Stream tracks to ATAK, WinTAK, and iTAK via TAK Server or SA Multicast. Pro feature.
Full REST API and WebSocket interface for integration and automation. Pro feature.
Modern web interface works on desktop, tablet, and mobile devices.
All processing happens locally. No cloud dependency, complete privacy.
Sub-second updates via WebSocket. See detections within moments.
Guided setup wizard with auto-detection of connected hardware.
Tamper-evident SHA-256 chained logs for regulatory compliance and post-incident analysis. Pro feature.
Built-in wireless access point for field deployments with no existing network infrastructure.
Direct laptop-to-Pi ethernet connection for isolated field operations. Zero network required.
RF Sentinel is a self-contained system in a ruggedized Pelican case. Set it up once, access it from any device on your network.
Place the Pelican case at your monitoring location. Connect external antennas to the weatherproof bulkhead connectors. Power from mains or the built-in LiFePO4 battery.
Multiple receivers scan simultaneously — ADS-B aircraft on 1090/978 MHz, AIS vessels on 162 MHz, Remote ID drones on WiFi/BLE, and weather data via SondeHub.
Open the web interface from any device on your network — laptop, tablet, or phone. All tracks appear on a single real-time map with filtering, history, and forensic logging.
Stream tracks to ATAK/WinTAK via TAK Server or SA Multicast. Export data as CSV, JSON, or KML. Access the REST API for custom integrations. (Pro)
RF Sentinel is available in two editions. Both include the core monitoring platform with perpetual licensing.

RF Sentinel provides passive monitoring for legitimate situational awareness needs.
Stream aircraft, vessels, and drone tracks directly to ATAK, WinTAK, or iTAK. Integrate RF awareness into your existing common operating picture.
Monitor aircraft traffic over your property. Track low-flying planes, helicopter activity, and log flight patterns for documentation purposes.
Awareness of aerial applicator aircraft, agricultural drones, and helicopter activity near your farming operations.
Track vessel traffic on nearby waterways. Monitor commercial shipping, recreational boating, and ferry schedules.
Integrate APRS tracking with your ham radio setup. Monitor local APRS activity and track balloon launches.
Track NWS radiosonde launches and weather balloon trajectories. Monitor balloon descents for potential recovery.
Everything you need to get started. Pre-configured hardware kits with RF Sentinel pre-installed and tested. External antennas sold separately.
RF Sentinel runs on a Raspberry Pi 5 inside a ruggedized Pelican case with integrated battery backup. Designed for low-power, continuous operation in fixed installations or portable field deployments.

PASSIVE MONITORING ONLY: RF Sentinel is a passive RF monitoring system that receives and displays publicly broadcast RF signals for informational and situational awareness purposes only. It does NOT transmit, jam, interfere with, intercept, disable, spoof, or take control of any aircraft, drone, vessel, or communication system.
NOT A COUNTER-UAS SYSTEM: RF Sentinel is NOT a Counter-Unmanned Aircraft System (C-UAS). It has NO capability to detect, track, identify, or mitigate unauthorized drones beyond passive monitoring of voluntarily broadcast signals (such as FAA Remote ID). In the United States, only authorized federal entities may operate C-UAS equipment under 6 U.S.C. § 124n.
NOT FOR SAFETY-CRITICAL APPLICATIONS: RF Sentinel is NOT designed or intended for use in any safety-critical application including air traffic control, flight planning, navigation, collision avoidance, emergency response, maritime navigation, or any application where failure could result in death, injury, or property damage. All data is for INFORMATIONAL PURPOSES ONLY.
NO WARRANTY: RF Sentinel is provided "AS IS" without warranty of any kind. Detection may be incomplete, delayed, or inaccurate. The user assumes all risk of use.
