Navigation and location experiment and method analysis of multiple radiation sources detection

It is a completely new navigation and positioning method by using the particle ray emitted from known targets, which provides a new idea for the existing navigation and location. Therefore, a multi-source navigation and positioning method is proposed, and the principle of locating the detector by four radioactive sources of 22Na, 60Co, 137Cs and 252Cf is analyzed, and an analog positioning system consisting of a detector, an operational amplifier, a digitizer and a sampling server is set up. Based on the simulation positioning system, the positioning method is verified experimentally, and the whole positioning process using the positioning method is reported. The location of the detector coordinates is (152.5, 231.8,182), which verifies the feasibility of the positioning method. The location result and the true coordinates of the detector (100,200,150) have error and the image is in the shadow. The factors that affect the positioning error are analyzed, which provides a new idea and method for the study of pulsar navigation and positioning.
