python rtklib 解算 rtk算法步骤 一、实时载波相位差分 我们知道,在利用GPS进行定位时,会受到各种各样因素的影响,为了消除这些误差源,必须使用两台以上的GPS接收机同步工作。GPS静态测量的方法是各个接收机独立观测,然后用后处理软件进行差分解算。那么对于RTK测量来说,仍然是差分解算,只不过是实时的差分计算。 也就是...

下面以python为例,实现rtcm32数据串口接受保存: import datetime import time import serial import os from FileUtil import FileUtil port = '/dev/ttyUSBnet' btl = 115200 current_path = os.path.dirname(os.path.abspath(__file__)) current_time = "B" + datetime.datetime.now().strftime('%Y_%m...
A truly literal translation of the C code would run very slowly, primarily because Python is an interpreted language and C is a compiled language. To make the python code run at a reasonable speed, many of the for loops in RTKLIB have been replaced with Numpy array operations. This need t...

朝这个方向迈出的第一步是用一组级联多项式系数替换查找表,以用一组更小的数字来近似表的内容。然后我将上述python代码的FFRT部分重写为RTKLIB C代码。示例代码还允许用户选择两个目标故障率之一。为了进一步简化解决方案,我取消了更高的固定故障率目标选项,仅支持 0.001 故障率目标。
Rtklib-py is a free and open source subset of RTKLIB written in Python. It was originally based on CSSRlib but has been rewritten to align very closely with the demo5 version of RTKLIB. It currently supports only PPK solutions using GPS, GLonass, and Galileo constellations. It supports most...
我在git上其实也上传了动态对比的一套简单的python对比工具,需要请后台回复 git,切换到mulfreq-spp分支,并拉取最新代码,工具在python文件夹下。 关于其他的,比如在rtkpos()函数之前的一些,观测数据读取,星历读取,以及一些为了支持多文件处理的缺省字段匹配的逻辑,个人不建议去阅读。
利用坐标转换程序,将定位结果从XYZ方向转换到ENU方向,测站坐标真值从IGS的周解坐标文件获取。 此处使用的GAMP__GOOD软件下载的snx文件。 定位的坐标解算使用的是RTKlib生成的POS文件。 如果对RTKLIB软件有所需要免费下载RTKLIB 2.4.3,点击此处。 ...
However, I suspect that winning the competition using RTKLIB will require more than just configuration changes and python script changes. I believe it will also require making changes to the RTKLIB code itself. As anyone who has worked with the RTKLIB code is probably aware, it can be quite ...
