Strategies for Advancing Maritime Domain Awareness through Space-Based Automatic Identification System Technologies
===
Maritime domain awareness (MDA) is the effective understanding of anything associated with the global maritime domain that could impact the security, safety, economy, or environment of a nation or region. MDA is essential for various purposes, such as maritime security, law enforcement, search and rescue, environmental protection, and fleet management. However, MDA faces many challenges, such as the vastness and complexity of the maritime domain, the diversity and dynamism of maritime activities, the limitations and gaps of terrestrial-based sensors, and the lack of interoperability and information sharing among stakeholders.
One of the promising technologies that can enhance MDA is the space-based automatic identification system (SAT-AIS). SAT-AIS is a system that uses satellites to receive and process the signals transmitted by the automatic identification system (AIS) devices installed on ships. AIS is a short-range coastal tracking system that provides identification and positioning information to both vessels and shore stations. AIS transponders automatically broadcast information at regular intervals, such as vessel name, type, size, position, course, speed, destination, and cargo. AIS signals have a horizontal range of about 40 nautical miles (74 km), meaning that AIS traffic information is only available around coastal zones or in a ship-to-ship zone.
SAT-AIS overcomes this limitation by using satellites orbiting around the earth to receive and relay AIS signals from any location on the globe. SAT-AIS can provide near-real-time global coverage of maritime traffic, especially in remote areas where terrestrial sensors are scarce or nonexistent. SAT-AIS can also complement other space-based sensors, such as synthetic aperture radar (SAR), optical sensors, and global navigation satellite systems reflectometry (GNSS-R), to provide a comprehensive picture of the maritime domain.
SAT-AIS has many benefits for advancing MDA, such as:
– Improving maritime situational awareness by providing timely and accurate information on vessel identity, location, movement, and activity.
– Enhancing maritime security by detecting and tracking suspicious or anomalous vessels, such as those involved in piracy, illegal fishing, smuggling, or terrorism.
– Supporting law enforcement by providing evidence and intelligence for investigations and prosecutions of maritime crimes.
– Facilitating search and rescue by locating and identifying vessels in distress or in need of assistance.
– Protecting the environment by monitoring and reporting on vessels carrying hazardous or polluting cargoes, or those violating emission regulations.
– Optimizing fleet management by enabling shipping companies and ship owners to monitor and control their vessels’ performance, efficiency, safety, and compliance.
However, SAT-AIS also faces some challenges and limitations that need to be addressed, such as:
– The high volume and complexity of AIS data that require efficient processing, analysis, fusion, and dissemination methods.
– The interference and collision of AIS signals that reduce the quality and reliability of SAT-AIS data.
– The spoofing and manipulation of AIS data that undermine the integrity and authenticity of SAT-AIS data.
– The legal and regulatory issues that affect the access and use of SAT-AIS data by different stakeholders.
– The cost and sustainability of SAT-AIS systems that depend on the availability and affordability of satellite resources.
Therefore, to fully exploit the potential of SAT-AIS for advancing MDA, some strategies are needed, such as:
– Developing innovative technologies and solutions for SAT-AIS data acquisition, processing, analysis, fusion, dissemination, and visualization.
– Establishing standards and protocols for SAT-AIS data quality assurance, validation, verification, authentication, encryption, and protection.
– Implementing policies and regulations for SAT-AIS data governance, sharing, exchange, interoperability, privacy, security, and ethics.
– Fostering collaboration and coordination among SAT-AIS stakeholders from different sectors, domains, regions, and levels.
– Promoting awareness and education on the benefits and challenges of SAT-AIS for MDA.
