定向Heading
其中1#主天线提供定位、用于Rover或Base,2#次天线提供航向。
1. 定向 NV08C-RTK-A + 1#主天线+2#次天线;
2. RTK 流动站:NV08C-RTK-A + 天线(RF 1#)+ 基站:NV08C-RTK或NV08C-RTK-A +天线 或虚拟基站;
3. 定向+RTK 流动站:NV08C-RTK-A +主天线(RF1#)+ 次天线(RF 2#)+ 基站:NV08C-RTK或NV08C-RTK-A +天线 或虚拟基站。
2米短基线0.1度航向精度。如果缩短基线到1米,航向精度降低到0.2度。
注意:定向依赖GNSS信号载波相位,属于高精度应用,对工作环境、工作条件要求较高。不建议过短基线,基线>0.5米。如果两条天线太近,第二条天线会影响第一条天线图形及相位中心稳定性,会产生“干扰”,影响航向精度;靠近建筑物、树木,GNSS信号受反射影响,可在天线下加直径20cm金属屏蔽,抵挡地面反射信号。
主要设置
指令: $PNVGRZB,BLS
请求基线状况及定向参数,包括固定解UTC时间、基于基线的北向、基于基线的东向、基线长度(计算两个天线中心相位长度)、基线与北向的角度、基线与水平的角度、工作模式等。
老版本固件:
$PNVGRTK,MODE,4
启动定向,自动输出BLS基线状况及航向。
$PNVGRZB,HDT
请求HDT真航向, $GPHDT语句包含在RTK NMEA协议($GPHDT - Heading,True),RTK FW 0027版固件开始支持。
RTK FW0027固件简要:
NV08C-RTK-A默认RTK+航向工作模式;支持TimeMark EVENT;增加 HDT(真航向)、SDP(位置标准方差)、SDV(速度标准方差)、SDH(航向标准方差), RZD(坐标方差2D RMS)、TME、TMU、TMC、VOG输出...
RTK FW0029固件简要:添加了HDT真北航向到$PNVGBLS默认输出中。不同基站互动,校准Glonass偏差。多路径环境改善。
Testing测试
注:双天线(双频)置于巴士车顶,分路器连接车内OEM617D (L1/L2)、NV08C-RTK-A(L1),在瑞士山路行驶。
NV08C-RTK-A几乎没有浮点,性能与OEM617D非常接近。
