| Popis: | The paper considers the introduction of the newest methods of topographic surveying into the educational and scientific process, using global navigation satellite systems (GNSS) at the Faculty of Geography of Moscow State University. It describes the designation and use of the current reference geodetic training network for the training of students within the program of topographic practice. The basic concepts and purpose of the equipment of the geodetic class of the user segment of GNSS, both the basic location (reference stations) and mobile complexes are disclosed. The technique of measuring and processing the accumulated data after field fixation (in static or kinematic modes) of geographic objects and phenomena using GNSS has been given. A constantly operating network of reference stations of the faculty has been described. A full-scale example of using the GNSS complex by students of the faculty of the study area is given, the collected materials have been used for subsequent modeling (relief restoration) based on the results of field measurements. Within the framework of the perspective development of the network of GNSS reference stations of the Moscow State University, the scheme of their location in the meridian direction on an ongoing basis has been shown, which will substantially expand the territorial coverage of the use of mobile GNSS complexes in geographic studies. Within the framework of the program of preservation of monuments of Russia’s cultural heritage, an example has been shown of the joint use of groundbased laser scanning techniques and a mobile GNSS complex conducted by students and teachers of leading Moscow universities and representatives of GFK Firm LLC. The result is the fixation of the geometric characteristics of the object in 1 cm steps in real coordinates, which makes it possible to carry out the necessary modeling, visualize the object in perspective form, carry out the necessary measurements, build sections, etc. The prospects for using unmanned aerial vehicles (UAVs) equipped with a digital camera and a GNSS complex have been discussed, with a view to largescale monitoring of the underlying surface. |
