Within the framework of the expanding technical and technological capabilities of scientific methods, of special interest are new ways of obtaining field measurements, which can be successfully applied in combination with traditional archaeological survey. The technology of unmanned shooting acts is one of such methods. In the course of work on the mapping of archaeological sites and the establishment of their boundaries, a comprehensive survey technology was developed and tested. Intermediate and final digital products have been created for all the objects. The first ones include orthomosaic, digital elevation models and arrays (clouds); the second ones include digital plans (on a scale of 1: 500–1: 5000) with coordinates of turning points and boundaries of sites. When carrying out a complex of field and office work, the technology of UAV shooting with the help of a drone of a copter type was worked out, the optimal position of the reference signs and their number for the shot sites were determined. We established the most favorable shooting conditions, under which weather conditions could differ significantly from those prescribed in the instructions. So, for example, it is possible to perform GNSS surveys and UAV surveys when precipitation are light and wind speeds up to 10 m / s. The resulting errors are compensated partly by the on-board accelerometer, and partly by the algorithms for geometric correction of images and mosaics in general.
