Algorithms of calculation of co-ordinates of a source of a radio emission in goniometric and measuring differences of distances radio systems with the minimum number of mobile carriers with error check of definition of a site of places of acceptance on the basis of an adaptive filtration a method of division of the expanded vector of a condition are considered. Results of statistical modelling are resulted. It is shown, that the error of definition of co-ordinates of places of acceptance leads to deterioration of accuracy of calculation of co-ordinates of a source of a radio emission by the traditional filter on the basis of local normal approximation. This most typical for a method measuring range differences. Error check of definition of co-ordinates of places of acceptance at the expense of their recalculation in equivalent noise of measurements of parametre of position or expansion of a vector of a condition allows to raise accuracy of calculation of co-ordinates. Thus the second approach is more effective.
