FIELD: physics, measuring.
SUBSTANCE: invention concerns measuring equipment and can be used for sea, aerial and land objects. The task in view is solved by that on the signals arriving from accelerometres, a part of INS, spot an absolute acceleration on the following linear connection: where gx - indications of the accelerometre measuring acceleration on a long axis of object with the INS mounted on it; gy - indications of the accelerometre measuring acceleration on a vertical axis; gz - indications of the accelerometre measuring acceleration on a transverse axis of object with the INS mounted on it; and during the moment when the absolute acceleration is equal to an acceleration due to gravity for terrain where the INS is, INS indications on pitch angles and tilt with the values calculated on the following linear connections: υ=:-arcsin gx/g; γ=-arctg gz/gy.
EFFECT: accuracy pinch of the gimballess inertial system, by making of the correction method of inertial navigating system (INS).
