Integrated surveying method for FOG inclinometer aided by cable length

  • 摘要: 为实现光纤陀螺(FOG)测斜仪高精度长时间测量,结合测井作业方式,提出基于卡尔曼滤波技术的电缆长度信息辅助的组合测量方法.介绍了捷联惯性测量系统(ISS)误差模型和电缆长度测量模型,设计了组合测量方法的总体方案,建立了组合测量系统误差状态模型及量测更新模型.采用半实物仿真计算对本文提出的组合测量方法进行了验证.仿真结果表明:14 400 s的仿真过程,井斜角误差小于0.02°,工具面角误差小于0.12°,方位角误差小于0.98°,位置误差小于47.5 m.相比纯惯性测量,误差得到了有效的抑制,保证了仪器长时间保精度的测量,提高了仪器的性能.
