文摘:為了保證靜電監控器的導航定位精度,需要了解靜電陀螺的姿態誤差特性,建立相應的誤差方程.本文採用球面三角形原理推導了導航定位誤差與陀螺姿態誤差的關系式.模擬結果表明,由初始定向誤差引起的經度誤差和距離誤差的時間特性是周期變化的;由陀螺漂移引起的經度誤差和距離誤差是隨時間發散的.因此,初始定向誤差和陀螺漂移的影響不能忽略,必須對其進行估計和補償People, ship and environment are all dynamic states, which form a comprehensive and mutual implication system. applied dynamic layout theory and optimum cybernetics make the comprehensive policy and dominance on system uncertainty due to complexity and changeability of the sea environment
