Development Nekrasov, M.I. and tests results Yevstifeyev, B.A. Blazhnov, V.D. Aksenenko The paper presents a micromechanical gyroscope (MMG), an inertial measurement unit (IMU) based on MMG and an integrated attitude and navigation system (IANS) developed in CSRI Elektropribor. The evolution and prospects for the development of MMG main components and MMG-based systems is considered. Test results are given. Yu.V. Bolotin, Calibration 13 V.P. Golikov, algorithms for a S.V. Larionov, gimbal inertial A.V. Trebukhov navigation system INS calibration problem is considered when the readings of accelerometers, torquers, and angular pick-offs in gimbals are used as measurement information. The readings of the latter are supposed to be rougher compared with the readings of accelerometers. It has been shown that under these conditions correct choice of the instrument reference frame is necessary for fine calibration of accelerometers. Method for introducing the instrument reference frame is proposed. It is based on the polar decomposition of coordinate transformation matrices and allows for reaching theoretically maximum calibration accuracy. Optimization methods for the calibration plan are discussed as well. I.V. Popova, A.M.
