L'invention concerne un système de sauvetage de navigation maritime basé sur un satellite BeiDou, lequel système comprend un terminal embarqué sur un navire (1), un centre de commande et de contrôle au sol (3) et un terminal de sauvetage (4), le terminal embarqué sur un navire (1), le centre de commande et de contrôle au sol (3) et le terminal de sauvetage (4) étant tous en liaison de communication avec un système de navigation par satellite BeiDou (2). Après que le centre de commande et de contrôle au sol (3) du système a reçu un message de détresse envoyé par un navire, une fonction de communication de messages courts spécifique au système de navigation par satellite BeiDou (2) peut être utilisée pour entrer en contact avec le navire en détresse, de manière à confirmer l'authenticité du message de détresse, de façon à réduire ainsi considérablement les fausses alertes. En même temps, le terminal embarqué sur un navire (1) du système est exempt de restrictions de facteurs externes, telles que des distances, des conditions météorologiques et maritimes, du fait de la fonction de communication de messages courts du BeiDou, et a des fonctions d'envoi actif d'informations de position concernant un navire en détresse à tout moment et de réalisation d'une communication de messages courts avec le centre de commande et de contrôle au sol (3) à tout moment ; et le terminal embarqué sur un navire est stable et hautement efficace, il peut envoyer avec précision et à temps des messages de détresse, et est utile pour qu'un personnel au sol puisse positionner et suivre des personnes en détresse, de façon à accélérer ainsi une vitesse de sauvetage.
