RF Spectrum Intelligence for
Seaports & Maritime Facilities

Why Seaports Are a High-Value RF Target

Seaports are complex, high-stakes environments where RF is both essential to operations and a vector for threat. Cargo handling systems, vessel communications, crane automation, safety radio, private LTE, CCTV backhaul, and AIS vessel tracking all share a congested spectrum environment — while adversaries increasingly use RF tools to surveil, disrupt, and penetrate port security.

Ports handle billions of dollars in cargo daily and represent critical nodes in national supply chains. An RF disruption — whether accidental interference in a crane automation network or a deliberate jamming attack on port communications — can halt operations and create safety and security cascades with consequences far beyond the facility.

DGS, in partnership with SEADAR, delivers the spectrum intelligence and maritime domain awareness that modern seaports need to protect operations, secure infrastructure, and maintain throughput.

Key Challenges

  • Multiple overlapping systems: VHF marine, cellular, WiFi, private LTE/5G, radar, AIS, and IoT
  • Threats from unauthorized transmitters near critical infrastructure
  • Growing use of drones around port facilities
  • Need for real-time awareness of both RF activity and vessel behavior
  • Pressure to increase throughput while maintaining safety and security

The RF Challenges Seaports Face

Spectrum Congestion in Industrial Environments

Seaports run on wireless. Crane automation, vehicle guidance, handheld radios, private LTE networks, vessel AIS, shore-to-ship communications, and industrial IoT all compete in a dense, reflective RF environment. Interference between these systems degrades automation reliability, slows cargo operations, and creates safety risks.

CLEARSITE™ provides continuous visibility into the port RF environment: identifying which systems are interfering with which, where congestion is worst, and what coexistence changes can restore performance.

Military UAV Drone Technology

Drone Threats at Port Facilities

Port facilities are increasingly targeted by drones — for surveillance, contraband delivery, or disruption of operations. Restricted airspace rules that govern airports do not universally apply to port facilities, making proactive detection even more critical.

CLEARSKY™ detects drone control and telemetry signals before aircraft are visible, providing early warning and enabling security teams to respond before drones reach cargo areas, vessel berths, or critical infrastructure.

Vessel-Based RF Threats

Ships bring their own RF environments into the port. Foreign vessels may carry unauthorized transmitters, signal collection equipment, or devices intended to interfere with port communications. CLEARSKY™, integrated with SEADAR’s vessel tracking, correlates RF anomalies with specific vessel identities and movements — connecting spectrum intelligence to the maritime operational picture.

GPS Spoofing & Navigation Disruption

GPS spoofing — deliberate manipulation of satellite navigation signals — is an increasing threat to maritime operations. Spoofed GPS can affect vessel navigation, port automation systems, and cargo tracking. CLEARSKY™’s RF anomaly detection identifies spoofing signatures in the local environment, providing early warning to port operators and vessel masters.

What DGS + SEADAR
Deliver for Seaports

  • Continuous RF monitoring across port, terminal, dock, and perimeter areas
  • CLEARSKY™ drone detection: control-link identification before aircraft are visible
  • Aboveground and underwater drone detection through SEADAR integration
  • RF anomaly detection correlated with SEADAR vessel tracking for attribution
  • GPS spoofing detection and navigation signal integrity monitoring
  • Interference management for crane automation, private LTE, and operational networks
  • Contraband device detection in cargo handling and restricted zones
  • RF forensics for incident investigation, insurance claims, and regulatory reporting
  • Pre-deployment assessments for port automation and private 5G expansions

What DGS Delivers

  • Continuous RF monitoring across the airfield, terminal, and perimeter
  • Detection and classification of drone control links and other unauthorized signals
  • RF forensics capabilities for incident reconstruction and investigation
  • RF performance and interference insights to support private 5G, CBRS, and smart airport initiatives
  • Portable kits for fast deployment during special events, construction, or emergencies

The DGS + SEADAR Advantage

Most port security systems see the physical domain or the cyber domain. DGS and SEADAR see the RF spectrum that connects and threatens both. By integrating CLEARSKY™’s RF intelligence with SEADAR’s maritime domain awareness, port security teams gain a unified operational picture: which vessel is near which berth, what RF activity is occurring in that zone, and whether the combination signals a threat requiring response.

This integrated capability is unique to the DGS-SEADAR partnership and specifically designed for the operational environment of modern seaports.
