In tests of an airborne radio range finder, measurement of the base by internal traverse of the direction line, radio geodetic determination of coordinates and laying out of skeleton routes along a series of points of the survey base were carried out. In distinction from use over flat terrain, flight heights were determined from barometric data for reduction of distances to the surface of an ellipsoid. Base measurements at 3000 and 4000 m were unsatisfactory, due to the presence of obstacles to passage of radio waves however, recordings at 5000 m were wavy, but readable. A method of determination of the root mean error is presented and the resulting errors are of the same order of magnitude as in aerial surveys at the same scale in flat regions.
