Abstract

The invention discloses a navigation signal active interference positioning method in a complex site environment, which comprises the following steps of: acquiring a satellite message sent by a positioning satellite, storing the satellite message into a message data group, calculating the Poisson distribution probability of the null run length average length based on the message data group, judging whether a navigation signal is interfered, and if the interference exists, judging whether the navigation signal is interfered. A sampling period is regulated and controlled, and a positioning optimization signal is generated; an active interference monitoring model is constructed based on the positioning optimization signal; an interference frequency range is determined and stored in a data set; a navigation equipment frequency receiving range is regulated based on the interference frequency data set; the invention further relates to related computer equipment and a storage medium, and the problem of active interference positioning of navigation signals in complex sites can be solved.
