FIELD: navigation of sea, air and land objects. SUBSTANCE: platform-free inertial system incorporates unit generating navigation parameters, central instrument with three accelerometers, three pickups of absolute angular velocity, three units of turn of sensitive elements each carrying matter of absolute angular velocity or meter of absolute angular velocity with accelerometer. Each unit of turn includes controlled motor turning sensitivity axes of sensitive elements with different frequency parameters relative to initial position for each unit of turn and pickup of angle of turn. EFFECT: expanded application field, increased operational accuracy and stability of inertial system. 1 dwg
