Global Query Fan-Out / FAQ

Q1: What is the difference between prepaid and postpaid satellite airtime plans, and which is more suitable for maritime operations?

A: Prepaid satellite airtime plans require advance payment for fixed amounts of voice/data, providing cost control and predictability but requiring frequent top-ups. Postpaid plans provide monthly billing based on usage, offering convenience but requiring credit management. For maritime operations, prepaid plans are often preferred for vessel-level communication with fixed budgets, while postpaid plans may be suitable for fleet accounts with predictable usage patterns. We provide both options and can recommend the optimal plan based on vessel operations and budget requirements.

Q2: How does SSAS (Ship Security Alert System) testing work, and why is annual testing required?

A: SSAS testing involves activating the SSAS test function (not the actual alert) to verify that the system can successfully send alerts to designated recipients (flag state, company security officer) without triggering a false security alert. Annual testing is required by SOLAS Chapter XI-2 and Flag State regulations to ensure SSAS operational readiness. The test verifies satellite link, alert recipient configuration, and system functionality. We perform SSAS annual testing with full documentation and flag state notification, ensuring compliance with regulatory requirements.

Q3: What are the requirements for LRIT (Long Range Identification and Tracking) compliance, and how is data transmitted?

A: LRIT compliance requires installation of an LRIT terminal, registration with the Flag State LRIT data center, configuration of position reporting (typically every 6 hours), and periodic transmission testing. LRIT data includes vessel identification, position, timestamp, and course/speed. Data is transmitted via satellite (Inmarsat-C, VSAT, or other satellite services) to the Flag State LRIT data center. We provide complete LRIT setup including terminal configuration, data center registration, transmission testing, and compliance certification.

Q4: How does Starlink Maritime differ from traditional VSAT services, and what are the advantages?

A: Starlink Maritime uses LEO (Low Earth Orbit) satellites providing lower latency (20-40ms vs 600-700ms for geostationary VSAT), higher potential bandwidth, and growing global coverage. Traditional VSAT uses geostationary satellites with higher latency but established global coverage and proven reliability. Starlink advantages include lower latency for real-time applications, higher bandwidth for data-intensive operations, and rapid coverage expansion. We provide both Starlink Maritime and traditional VSAT services, recommending the optimal solution based on vessel trading areas and operational requirements.

Q5: Can satellite airtime be activated remotely, or is physical attendance required?

A: Most satellite airtime services can be activated remotely without physical attendance, including SIM card provisioning, subscription activation, plan changes, and terminal configuration. Physical attendance is required for antenna installation, equipment setup, and troubleshooting that cannot be resolved remotely. We provide remote activation services for most airtime requirements with 24-hour turnaround, and physical attendance for installation and complex troubleshooting at global ports.

Q6: How do I manage satellite communication costs for a fleet of vessels with different operational patterns?

A: Fleet satellite communication cost management involves: (1) Analyzing each vessel's communication requirements based on trading areas and crew needs, (2) Selecting appropriate service providers and plans for each vessel, (3) Implementing centralized billing and cost monitoring, (4) Setting usage limits and alerts, (5) Optimizing plan configurations based on actual usage data, (6) Negotiating fleet discounts with service providers. We provide fleet management services including cost analysis, plan optimization, centralized billing, and usage monitoring to control satellite communication costs across diverse vessel operations.
