Por meio do Aplicativo NAVSEG, o Comandante da Embarcação brasileira poderá informar seu plano de viagem (Aviso de saída), o que possibilitará o acompanhamento pelas marinas, clubes náuticos, Capitanias, Delegacias e Agências (CDA). Para isso, é necessário que o comandante da embarcação habilite a localização do GPS de seu dispositivo móvel (smartphone ou tablet) e autorize a transmissão dessas informações para a Marinha do Brasil, o que poderá ser realizado no próprio aplicativo NAVSEG. A posição da embarcação será transmitida a cada 30 minutos, devendo o comandante navegar próximo da costa, o suficiente para que o sinal do dispositivo esteja ao alcance da operadora de telefonia contratada. O maior propósito é a preservação da vida humana no mar, caso ocorra algum problema com as embarcações navegando na navegação interior ou na costa brasileira.
