为了研究一种适合船用的启动快、全天候、低成本、没有误差积累的测姿系统,根据船体甲板结构布局,设计了一套GPS测姿系统.系统采用4台双频GPS接收机,4天线棱形布局,艏艉基线约33 m,利用GPS载波相位测姿技术确定船舶姿态.海上动态试验时以惯导和光电经纬仪为数据比对基准进行精度分析.结果表明系统已基本达到了全时段测量的能力,其有效数据覆盖率可达94.8%以上,航向角系统误差小于18",纵摇角系统误差小于28",横摇角系统误差小于80".系统已可作为大型船舶姿态测量的主要测量手段之一,同时由于其航向精度较高,可作为惯导系统航向校准的补充手段.

s:To study a quick start-up, all weather, low cost and no error-accumulation attitude determnation system,a attitude determination system by GPS carrier phase was designed with four dual frequency GPS receivers and four antennae based on the ship hull’s structure. The antennae are positioned on the deck with rhombus layout. The longest baseline between the antennae is about 33 meters. In the dynamic tests on the sea, the INS and photo-electric theodolite are the reference. The tests show that effective data coverage of the system is more than 94.8%, the systematic errors of the heading angles, pitch angles and roll angles are less than 18", 28"and 80", reapectively. Due to its high heading accuracy, the system of attitude determination by GPS carrier phase can be used in the big ships as one of the main attitude determination equipments, and can be used in course angle calibration.
