Aerospace Instrument-Making Annotation << Back About accuracy control of BINS algorithms. A.V. Babichenko, A.P. Rogalev The basic type of gyroscope sensors used for body-mounted inertial navigational systems (BINS) are angular movement sensors (AMS). The AMS outputs (“quasi-coordinates”) are proportional to increments of integrals of angular rates about sensitivity axes of these devices. The BINS algorithms process the “quasi-coordinates” to form the orientation vector of an object where the sensors are mounted. The objective control of the algorithm consists in forming a desired input signal, obtaining a corresponding output signal and comparison of the latter with its desired value. At the same time the relationship between the desired values of input and output signals must be described analytically. The article shows that for BINS with AMS it is almost impossible to get such a relationship between an input (“quasi-coordinates”) and an output (orientation vector) during voluntary movement of an object.
