FIELD: high-precision navigation systems for ground mobile objects. SUBSTANCE: proposed ground navigation system includes mechanical speed transmitter, self-orienting gyroscopic course and roll indication system incorporating transmitters of accelerometers and measuring angles of course, roll and pitch of object. System also has coordinator incorporating computer and device for input/output of navigational information. Navigation system is connected with links of accelerometers and computer via proper analog-to-digital converters and with links of computer to servo system of gyroscopic level flight, that is, to second inputs of amplifiers of accelerometers via proper digital-to-analog converters. Computer processes information from transmitters of speed and course and from both accelerometers which makes it possible to compensate for action of linear and centripetal accelerations on system of leveling of course and roll indication system and to correct readings of mechanical speed transmitter. EFFECT: enhanced precision of determination of coordinates of position of ground object while it moves. 1 cl, 1 dwg
