State-of-the-art marine surveillance system of the Brazilian Navy

In 2021, the Brazilian Navy initiated a project called the Sisgaaz Rio Phase Program to implement a state-of-the-art maritime monitoring system.

95% of Brazil’s international trade in goods is by sea.

This system, a part of the larger Blue Amazon Management System (Sisgaaz), was designed to monitor the waters between the Castelhanos Lighthouse and Cabo Frio Lighthouse within Brazilian Jurisdictional Waters, extending up to 200 nautical miles from the baselines.

Designed with AI and multi-source fusion algorithms, the ambitious project required contributions from a number of companies.

Twenty-eight companies expressed interest and received the necessary documentation.

The potential contributors ranged from aerospace company Airbus to defense firms like Embraer and Raytheon.

An analysis of these contributors’ suggestions resulted in the alignment of 13 main themes.

Key among them was the incorporation of existing products and components to meet the Navy’s requirements and the selection of surveillance units locations.

This collaborative approach was seen as a way to reduce costs, risks, and timelines while boosting the Brazilian Defense Industrial Base’s (BID) ability to meet Navy requirements.

Another significant development was the consideration of Over The Horizon (OTH) surface wave radar for monitoring the 200-nautical mile range, with six companies proposing this technology.

The utilization of existing technologies in the Brazilian BID is seen as an important step toward the realization of this project.

As of July 2023, the project has progressed to a stage where Requests for Proposal (RFP) are due to be sent out to interested companies.

These RFPs represent a crucial step toward the construction of Coastal Surveillance Units on the coast of Rio de Janeiro, a primary objective of the Sisgaaz Rio Phase Program.

The Sisgaaz Program aims to secure the Blue Amazon region by safeguarding its waters, resources, vessels, and infrastructure against threats, emergencies, and illegal activities.

Ultimately, it is a strategic initiative contributing to Brazil’s national development and defense.
