• View next pass predictions with elevation and duration

📶 WiFi Mode

• Requires a WiFi adapter capable of monitor mode
• Click "Enable Monitor" to put adapter in monitor mode
• Scans all channels or lock to a specific channel
• Detects drones by SSID patterns and manufacturer OUI
• Rogue AP detection flags same SSID on multiple BSSIDs
• Click network rows to target for deauth or handshake capture

🔵 Bluetooth Mode

• Scans for classic Bluetooth and BLE devices

• Bookmark frequencies for quick recall
• Quick tune presets for emergency and marine channels

🔍 TSCM Mode

• Technical Surveillance Countermeasures sweep
• Scans for unknown RF transmitters, WiFi devices, Bluetooth
• Baseline comparison to detect new/anomalous devices
• Threat classification: Critical, High, Medium, Low
• Useful for security audits and bug sweeps
• Note: This feature is in early development

Monitor Mode

• Enable Monitor: Puts WiFi adapter in monitor mode for passive scanning
• Kill Processes: Optional - stops NetworkManager/wpa_supplicant (may drop other connections)
• Some adapters rename when entering monitor mode (e.g., wlan0 → wlan0mon)

Handshake Capture

• Click "Capture" on a network to start targeted handshake capture
• Status panel shows capture progress and file location
• Use deauth to force clients to reconnect (only on authorized networks!)
• Handshake files saved to /tmp/intercept_handshake_*.cap

Drone Detection

• Drones detected by SSID patterns (DJI, Parrot, Autel, etc.)
• Also detected by manufacturer OUI in MAC address
• Distance estimated from signal strength (approximate)
• Click drone count in stats bar to see all detected drones

Rogue AP Detection

• Flags networks where same SSID appears on multiple BSSIDs
• Could indicate evil twin attack or legitimate multi-AP setup
• Click rogue count to see which SSIDs are flagged

Proximity Alerts

• Add MAC addresses to watch list for alerts when detected
• Watch list persists in browser localStorage
• Useful for tracking specific devices

Client Probe Analysis

• Shows what networks client devices are looking for
• Orange highlights indicate sensitive/private network names
• Reveals user location history (home, work, hotels, airports)
• Useful for security awareness and pen test reports

ADS-B Tracking

• Receives ADS-B broadcasts on 1090 MHz from aircraft transponders
• Displays position, altitude, speed, heading, and squawk code
• Interactive map and radar scope views available
• Click aircraft to see detailed telemetry and photos
• Emergency squawk codes (7500, 7600, 7700) highlighted

ACARS Messaging

• ACARS (Aircraft Communications Addressing and Reporting System)
• Decodes VHF datalink messages between aircraft and ground
• Requires a second SDR (separate from ADS-B)
• Regional frequencies vary - select N. America, Europe, or Asia-Pacific
• Messages include flight info, weather, OOOI events, and free text

ACARS Frequencies

• N. America: 130.025, 130.450, 131.550 MHz
• Europe: 131.525, 131.725, 131.550 MHz
• Asia-Pacific: 131.550, 131.450 MHz

Airband Audio

• Listen to aviation voice communications (AM mode)
• Requires RTL-SDR or compatible SDR hardware
• Common frequencies: 118-137 MHz (civil aviation band)
• 121.5 MHz is the international emergency/guard frequency

Full Dashboard

• Click "Open Full Dashboard" for expanded ADS-B view
