An analytical bank-and-climb gyro unit supplies the flight crew with information about aircraft angular movement relative to the local vertical. This article describes the particular principles of unit operation providing a step by step explanation of principles governing the operation of the analytical bank-and-climb gyro unit and provides a kinematic scheme of the unit. The article also gives an insight into the occurrence of errors in the bank-and-climb gyro unit as well as explains their significance.

-Inertial system errors in case of using the new structural correction method have been determined. Inertial system errors, which determine the kinematic parameters of aircraft movement, are finally generated in the computing circuit. This is the part of inertial system structure which is presented as a closed loop with a feedback. The forward circuit of the main loop consists of several velocity and distance integrators connected in series. Accelerometer signal corrections are calculated in the feedback loop. New corrective circuits have been introduced to the inertial system structure. And the errors of the changed system have been determined. The structural corrective circuits got signals from exterior onboard navigation systems. The conducted research has shown that the use of structural corrective circuits in some cases leads to a considerable decrease of inertial system errors. It means that the new structural method of inertial system correction provides positive results. Further research of inertial system errors should be conducted for the case of its full structure.

Nowadays autonomous measurement systems are applied for the determination of the cinematic parameters of object motion. The principle of operation of such systems is based on the measurement of the object motion acceleration with the further integration of the accelerometer’s signal. These measurement systems are called inertial systems. Platform-less inertial systems are widely used for these purposes. Their specific property is an installation of the primary information sensors directly on the constructive elements of the object case. The inertial measurement systems have also a negative feature to accumulate constantly the errors of the system.
