Research on Ship Location Algorithms for Anti Network Attacks

When hackers carry out network attacks on Beidou satellites, which affect the visible number of satellites and signal transmission, ships cannot perform normal positioning. Therefore, under the premise of network attacks on the Beidou satellite, this article uses a mathematical model of pseudo range positioning to solve the ship's position using an improved least squares algorithm and an improved Kalman filtering algorithm, respectively. The simulation results show that when part of the signal information is lost, the two improved positioning algorithms proposed can effectively locate ships, which has a certain improvement in accuracy compared to traditional positioning algorithms.
