There is a global trend towards an increase in the weight and dimensions of the aircraft fleet. At the same time, the load on aerodrome pavements increases, which contributes to their faster wear, changes in the pavement profile, and the appearance of defects that threaten flight safety. Therefore, constant monitoring of the condition of airfield pavements is carried out, in particular, the determination of its profile. A robotic complex has been developed for leveling the runway. The complex includes mobile leveling devices, mobile leveling rods, which are located on the runway during the performance of leveling, and a control device located at the central control station of technical systems of the airport. The control device contains the following blocks: control with a monitor; processing and storage of infor- mation; an intelligent subsystem with a set of logistics programs; geographic information system with GPS receiver; signal coding; reception and transmission of radio signals. Mobile levelers and mobile leveling rods are controlled from the central station and transmit coded information to the central station via radio communication channels. The mobile leveling rod is similar in design to a mobile leveling device due to the absence of a rangefinder measurement unit, a turning unit and the optoelectronic device itself. The movement of robotic mobile leveling devices and sighting targets with stops for measurements is carried out according to a pre-compiled program transmitted via coded radio communication channels. For the initial ones, the marks of the benchmarks are used, the horizontal plates of which are laid flush with the surface of the runway at its lateral ends, along which the steps of precise leveling are preliminarily laid. The proposed robotic complex allows to quickly determine the marks of the runway in automatic mode with an adjustable scanning step and build longitudinal and transverse surface profiles.
