INERTIAL NAVIGATION ACCURACY AND ACCELEROMETERS WITH DAMPING
Journal Title: Електроніка та системи управління - Year 2018, Vol 3, Issue 57
Abstract
Nowadays an anxiously important problem is the creation of the low-cost gyro-free inertial navigation systems. That is why we focus primarily on linear accelerometer to avoid gyro using. The problem of inertial navigation accuracy with using of accelerometers in inertial measurement unit are discussed. It is shown that a strict successive analysis of accelerometer measurement procedure makes it possible to understand probable new source of errors in the value estimation of the disturbing force magnitude. If do not take into account these new possible errors any self-adjusting system of an airplane may be functionally unreliable. These errors arise primarily when temporal duration of disturbing force is less than some critical time τ, which depends on the given characteristics of an aircraft Inertial Navigation System and aircraft itself. The method of finding τ is proposed. A presence of a damping force in the proof mass motion equation is examined.
