Olá tudo bem? Somos estudantes do SENAI e estamos fazendo um nano satélite de TCC. Nós precisamos de ajuda para fazer o histórico de GPS na Wegnology.

Este é o nosso código, nós queremos que apareça a localização do satélite no dashboard.
esse é o nosso dashboard, o atributo GPS já esta criado mas não sabemos configura-lo.
