Abstract
A present work considers a problem to maintenance demanded characteristics of independent navigation system with small weight, size and cost. It investigates methods that increase navigation’s accuracy of strapdown inertial navigation system (SINS). It is offered a hybrid principle of construction of inertial navigation systems as a way of improvement characteristics of SINS’s accuracy. The hybrid inertial navigation system (HINS) represents the strapdown inertial measuring unit in the biaxial gimbal suspension with static indicator gyrostabilization. This constructive decision allows to improve characteristics of navigation system’s accuracy, at the same time it meet the demands to keep acceptable size, weight, cost and gives possibility to fulfill unlimited maneuvers by object and autonomy work of control system.Keywords:
