Resumo

Os sistemas GNSS, como GPS e GLONASS, são amplamente usados para localização e sincronização de tempo. No entanto, são vulneráveis a jamming (interferência) e spoofing (falsificação de sinal), comprometendo sua confiabilidade. Este trabalho investiga experimentalmente a suscetibilidade de receptores GPS e GLONASS a sinais de jamming gerados por rádios definidos por software (SDRs) de baixo custo, utilizando o HackRF com firmware Mayhem. Emitindo sinais de interferência, avaliou-se a degradação do sinal por meio do GPS Test e do dashboard do SEL-2488. Os resultados mostram que, mesmo a múltiplas distâncias, ocorre perda significativa ou interrupção total. Dessa forma, conclui-se que SDRs acessíveis representam riscos reais, reforçando a necessidade de proteção e monitoramento.
