Low cost inertial navigation systems (INS) are systems in which gyroscopes are characterized by drift values of 5...10 degrees per hour. Currently, such systems are widely distributed due to their low cost and availability in the market. The use of low cost strapdown inertial navigation systems (SINS) for determining orientation angles in the autonomous mode (without correction from an external source of information) is fundamentally limited due to errors that grow with time. To improve the accuracy of determining the orientation angles of low-current SINS in the AHRS mode, a method for processing navigation information is proposed using a multiplatform approach to constructing a navigation algorithm and generating system output signals. The synthesis of such an algorithm and its application can significantly reduce the magnitude of errors in the orientation of the cursor. The implementation of the proposed method is considered on a specific example for a cursor mounted on a helicopter
