FIELD: measuring equipment.
SUBSTANCE: proposed invention relates to measurement equipment, in particular to determination of longitudinal evenness of road surface using mobile objects or vehicles. Device comprises bogie (1) including measuring wheel (2) and distance travelled sensor (odometer) (3), fibre-optic gyroscope (4) and correction unit (5) installed on the mobile object, computer (6) with a software-computing system for processing incoming information. Fibre-optic gyroscope (4) is connected by the first output to the first input of computer (6), which by the second input/output is connected to the first input/output of correction unit (5), the second input of which is connected to the first output of distance travelled sensor (3), which is connected through the second output to the third input of the computer.
EFFECT: higher accuracy of measurements of uneven surfaces of roads and airfields.
