FIELD: physics.
SUBSTANCE: navigation system comprises case with lateral, top and bottom faces, inner chamber, three fiber optic gyros arranged on side of two adjacent lateral faces and top face, and three accelerometers. Said case is made up of bearing support with shape approximating to cuboid. Gyros and accelerometers are provided with protective covers and secured on base surfaces to allow orthogonality of their measuring axes. Adjacent lateral faces are provided with protective jackets to house gyros and accelerometers. Protective jacket inner surface features complex raised shape of said base surfaces made up of basic support elements arranged along edges of jacket inner surface.
EFFECT: expanded operating performances.
