Abstract: FIELD: instrument making; navigation.SUBSTANCE: invention relates to the field of navigation instrumentation and can be used for the placement and testing of satellite navigation systems, which is installed on the chassis of land vehicles. Proposed method consists in the fact that the ground vehicle is used for control, on which the elements of the controlled systems are mounted using technological means, before the control operations, operations on the technological burn-in and calibration are carried out; the control process is divided into functional blocks of control operations, including the block of operations for control of working capacity and the block of control operations for determining accuracy characteristics. As a technological ground vehicle, a fully equipped topographic survey vehicle is used on the basis of an all-terrain vehicle with the van body, satellite goniometric navigation equipment (SGNE) and automated workplace (AWS) are additionally placed on the topographic survey vehicle to ensure its configuration and maintenance, placement of the SGNA antenna modules is carried out using the technological base, which provides for the mounting of the modules in the required configuration in order to obtain the lowest possible visibility shading and to prevent reflected modules from getting to the antenna modules, for which the technological base is installed on a mounting plate rigidly fixed on the roof of the box body, which allows to obtain the necessary orientation of the antenna modules relative to the longitudinal axis of the topographic survey vehicle, the placement of the goniometrical measurement unit of SGNE is made in the body of the van with the orientation of its building axes relative to the axes of the inertial navigation system (INS) from the topographic survey vehicle structure with an error not exceeding the specified one, for which the slab for the installation of the INS is equipped with the platform for the placement of the unit of angular measurements and the installation of optical quadrants, the placement of the automated workplace and the SGNE receiving-computing unit is carried out in the body of the van on the platform that is fixed on the desk of the operator’s workplace. In this case, the platform is made in the form of a rectangular slab with an inclined rack rigidly mounted on it, which is located at an angle to the lateral surfaces of the slab, the block of control operations for the control of health includes a check of the functioning of SGNE and AWS as part of the topographic survey vehicle, ensuring the determination of navigation parameters, interaction of SGNE with AWS, displaying and recording of the AWS measurement results, verification of the electromagnetic compatibility of the equipment with the standard radio electronic means of topographic survey vehicle. In the process of forming the method, it is possible to use the equipment as part of the accommodation facility and assess the compliance of the results with the specified requirements when placed at the real facility.EFFECT: broader functional capabilities.1 cl, 5 dwg
