About the Possibility of Integrating Information from Satellite Navigation Systems

This article presents the options for the integration of secondary navigation information of satellite navigation systems and the results of modeling the possibility of navigation measurements accuracy improvement during integration. Integration options are based on the method of determining the location of a moving object in space by imposing restrictions associated with the dynamic properties of the object. This method is recursive and is based on the use of secondary navigation information and readings of on-board meters of motion parameters, when each navigation measurement predicts the area of the possible location of the object at the time of subsequent navigation measurements. The corrected location of the object is considered to be the intersection of the areas of space of subsequent navigation measurements with the previously predicted areas of space. As a result of integration of navigation information of satellite navigation systems, the frequency of navigation data updates and the accuracy of navigation location of a moving object increase.
