Passive Monitoring System — NOT a Counter-UAS Solution

RF Sentinel is a passive receive-only RF monitoring system for situational awareness purposes only. It does NOT transmit, jam, interfere with, or disable any aircraft, drone, or vessel. RF Sentinel is NOT a Counter-UAS (C-UAS) system and provides no capability to mitigate or neutralize threats.

Six Signal Types. One Unified View.

RF Sentinel monitors multiple RF bands simultaneously, displaying all detected signals on a single real-time map interface.

✈️
Standard

ADS-B Aircraft

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.

Callsign Altitude Speed Squawk
🚢
Standard

AIS Vessels

161.975 / 162.025 MHz

Track ships, boats, and maritime vessels broadcasting AIS position reports. Ideal for coastal properties and waterfront monitoring.

MMSI Vessel Name Ship Type Destination
🛸
Standard

FAA Remote ID

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.

Serial Number Operator Loc Dual-Band BLE 5
📡
Pro Only

FPV & Control Links

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.

Analog FPV DJI Digital ELRS Crossfire
🎈
Standard

Weather Balloons

SondeHub API

Track radiosondes and weather balloons in your area via SondeHub. Monitor NWS balloon launches and descending equipment for potential recovery.

Altitude Ascent Rate Temperature Humidity
📻
Standard

APRS Amateur Radio

144.390 MHz

Monitor amateur radio APRS position reports. Track ham radio operators, mobile stations, and APRS-equipped assets in your region.

📶

WiFi AP Mode

Built-in wireless access point for field deployments with no existing network infrastructure.

🔌

Ethernet Direct Link

Direct laptop-to-Pi ethernet connection for isolated field operations. Zero network required.

Deploy in Minutes. Monitor 24/7.

RF Sentinel is a self-contained system in a ruggedized Pelican case. Set it up once, access it from any device on your network.

📦
Step 1

Deploy the Kit

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.

📡
Step 2

Receive RF Signals

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.

🗺️
Step 3

View the Map

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.

🎯
Step 4

Integrate & Export

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)
