NAVSEG is an Android application developed by Serviços e Informações do Brasil. It falls under the category of Travel & Navigation, specifically Maps & GPS. This free app is designed to assist Brazilian boat commanders in sharing their travel plans and enabling tracking by marinas, nautical clubs, Captains, Delegations, and Agencies (CDA).

To utilize NAVSEG, boat commanders need to enable the GPS location on their mobile devices (smartphones or tablets) and authorize the transmission of this information to the Brazilian Navy through the app itself. The app will transmit the boat's position every 30 minutes, requiring the commander to navigate within close proximity to the coast, ensuring a stable signal from their contracted telecommunications provider.

The primary objective of NAVSEG is to prioritize the safety of human life at sea, providing a reliable tracking system for boats navigating the Brazilian coastline and inland waterways.
