L200 FINETRACK
应用
•Accurate ROV positioning,
•Surface vessel when corrupted positioning data
特点
•基于惯性导航系统（INS）技术。
•集成了LBL声学范围观测和/或USBL，GPS并且DVL辅助惯性位置。
•有效的后处理脚本
•处理时间短，不断输出位置。对于预期缺乏任何辅助来源的工程而言表现优异。
•协助在有噪音环境下工作的USBL计算平滑的实时轨道
•L200的解算依赖于多普勒。如果底部锁定丢失，则不会得到解算。
•Based on Inertial Navigation System (INS) technology.
•Integrates LBL acoustic range observations and / or USBL, GPS and DVL aided inertial position.
•Effective post-processing script (processed solution is usually twice as good as real-time solution).
•Handles short, constantly outputting position. Excellent for projects where short lack of any aiding source is expected.
•Computes smooth real time track even if aided with noisy USBL.
•L200 solution is very much Doppler dependent. If bottom lock is lost, solution is not computed.
技术参数
•横摇纵倾精度优于0.05° (1).
•艏向精度优于0.5° (1)
•硬件依赖：非常依赖于多普勒。如果3分钟内得不到定位辅助，那么预计将会有1.5米的飘逸
•Pitch and roll accuracy better than 0.05° (1).
•Heading accuracy better than 0.5° (1).
•Hardware dependent：Very much Doppler dependent. After 3 minutes without position aiding, drift of 1.5 m (1) can be expected
