The invention provides a pseudo satellite based position safety protection method. The method includes that pseudo base stations are arranged around a forbidden area so as to form a continuous protection network, wherein the pseudo base stations are pseudo satellite signal transmitters and the forbidden area is a to-be-protected sensitive area; the pseudo base stations transmit pseudo satellite signals whose power is 3 db greater than that of real satellite signals. According to the invention, the pseudo base stations are arranged around the forbidden area and valid pseudo satellite signals are transmitted, so that the continuous protection network is formed. As for a satellite receiver, when the power of the pseudo satellite signals is 3 db greater than that of the real satellite signals,error longitude and latitude information can be generated and real satellite signals can be hidden. By adopting the method provided by the invention, malicious collection of national mapping geographic position information can be prevented and an aim of protecting the position safety of sensitive areas can be achieved. Also, the method can be applied to terrorist attack prevention and can also beapplied to navigation position control of unmanned vehicles, unmanned air vehicles and robots.
