Accuracy improving of radio emitter position fixing is sufficient in the field of radio monitoring, communication intelligence, radio navigation and radio geodesy. This paper represents results of errors estimation in radio emitter position fixing process applying spherical approximation of the Earth surface obtained by means of numerical simulation. Study of values of these errors was paid little attention in scientific literature. Besides that there are no indications as for development and implementation of algorithms accounting for Earth spheroid shape.
