IMPROVEMENT OF METHODS OF METROLOGICAL CONTROL OF GEODESIC SURVEYS DURING THE IMPLEMENTATION OF THE “GROUND GEODESIC SUPPORT COMPLEX”

Abstract

Modern geodetic instruments are convenient to use, highly productive, and provide high accuracy of measurements. Their proper operation requires in-depth knowledge and skills from the performers. Therefore, the curriculum of the land management specialty (193) includes the discipline “Electronic geodetic instruments”, during which the design and metrological characteristics of modern geodetic instruments, as well as methods of metrological control, are studied. High-precision geodetic measurements require such measuring instruments (MI) that would ensure maximum productivity during field measurements and high stability of their main technical parameters. The desire for partial or complete automation of measurement processes has led to the creation of MIs that require extremely careful handling and the possibility of constant monitoring of their normal operational suitability.Currently, metrological control of geodetic instruments is implemented using special laboratory facilities and geodetic polygons, but the number of metrological laboratories that provide services for metrological control of measuring instruments (MI) in Ukraine is insufficient.Many years of experience in operating measuring equipment in Ukraine (theodolites, levels, total stations, gyrocompasses, tape measures, etc.) indicate the need for constant monitoring of their performance and stability of parameters before and after topographic and geodetic works due to the high probability of damage to the device both due to uncomfortable working conditions at the facilities and due to unfavorable conditions for transporting measuring equipment to the place of work and back.The Ground Geodetic Support Complex (GGS) at the University is designed for inspections, adjustments, research and calibration of geodetic measuring equipment. Operation of the GGS eliminates the possibility of using faulty geodetic measuring equipment in operation; reduces time spent on calibrating electronic devices by eliminating its transportation to the points of the output sides of the state geodetic network (SGN).
