    Nonorthogonal Gyroscopic Instrument for Measuring Vector of Aircraft Angular Rate
    (National Aviation University, 2023-03-07) Chorna, Vladyslav Serhiivna; Чорна, Владислава Сергіївна
    The advantages of a strap-down inertial navigation system are relative cheapness (it is possible to use sensors from the “low cost” category), small dimensions and weight, and low power consumption. These advantages are especially clearly seen in SINS built on micromechanical navigation sensors (gyroscopes - MMG, accelerometers - MMA). Blocks of linear micromechanical accelerometers are used as sensors of the apparent acceleration of a moving object as part of inertial navigation systems. They do not have high accuracy characteristics (if we consider inexpensive MMA). However, there are tasks for which they are well suited. For example, in small aircraft, small size and weight, coupled with a low power consumption of MMA units, bring many benefits. The same applies to the automotive industry, where they are integrated with satellite systems (GPS, GLONASS, etc.). One of the serious problems of low-cost micromechanical sensors is random zero drift. In simple terms, drift is when the sensor indicates that the object is rotating (MMG drift), when in fact there is no rotation. Drift has a constant component, which can be compensated, and a random component, which is difficult to compensate. There are different ways to deal with random errors. One of them is the construction of a non-orthogonal SINS with information redundancy. This thesis has made a number of significant contributions to the field of aviation reliability and flight safety.
