Potential Possibilities of Highly Accurate Satellite Navigation Use for Landing Operations of Unmanned Aerial Systems

The results of MultiGNSS experimental research in precise positioning mode with TerraStar corrections are presented. The potential possibilities to ensure (provide) safe landing operation of Unmanned Aerial Systems of all categories, including CAT III meteorological minimum, are demonstrated. The errors of vertical coordinate determination are proposed to be estimated in two vertical planes (East Up and North Up correspondently). Experimental data approve accuracy of coordinates determination to be 10 cm (99
^%
) for horizontal plane and 18 cm (99%) for vertical planes.
