RTKlib关于高精度GPS动态定位函数与处理过程整理
精密GPS动态测量采用载波相位差分技术,其标准测量模式为,一台GPS接收机置于已知点,作为基准站来进行静态测量,另一台GPS接收机置于载体上,作为流动站来进行动态测量。两台接收机同步观测相同的卫星,然后将两台GPS接收机的观测值进行组合处理,就可以获得流动站相对于基准站的坐标和速度。本文主要介绍用RTKLIB 实现精密动态定位的过程,该过程包括观测文件和导航文件的读取、基准站位置的计算、流动站位置的求解、运行结果的输出,下面将分块讨论。(Precision GPS dynamic measurement using carrier phase difference technology, the standard measurement mode, a GPS receiver placed at a known point, as a base station for static measurement, another GPS receiver placed on the carrier, as a mobile station Perform dynamic measurements. The two satellites simultaneously observe the same satellite and then combine the observations of the two GPS receivers to obtain the coordinates and speed of the rover relative to the base station. This paper mainly introduces the process of realizing dynamic dynamic positioning with RTKLIB. The process includes reading the observation file and navigation file, calculating the base station position, solving the position of the mobile station, and outputting the result of the operation.)

读者写者问题
说明: 1、定义一个数据缓存buffer及用于实现同步互斥的信号量。
2、定义一个读者函数:
?当有写者在占用buffer时,读者应该等待,直到写者不再使用该buffer。
?当有其他读者在占用buffer时,读者可对buffer进行读取操作。
?当buffer中有数据时,则从其中读取一个数据,并显示然后退出。
?当buffer中没有数据时,应等待,直到buffer中有数据可读。
3、定义一个写者函数
?当有读者在占用buffer时,写者应该等待,直到所有的读者都退出为止。
?当有其他写者占用buffer时,该写者应该等待,直到占用buffer的写者退出为止。
?当buffer有空闲时,写者应该在buffer中写入一个数据并退出。
?当buffer满时,写者应该等待,直到buffer有空闲为止。
4、定义主函数,在其中可以任意创建读者与写者。
可根据用户输入创建读者或写者进程(线程)。(1. Define a data buffer and semaphores for synchronization and mutual exclusion.
2. Define a reader function:
When a writer is occupying the buffer, the reader should wait until the writer no longer uses the buffer.
When other readers occupy the buffer, they can read the buffer.
When there is data in the buffer, read a data from it, display and exit.
When there is no data in the buffer, wait until the data in the buffer is readable.
3. Define a writer function
When a reader is occupying the buffer, the writer should wait until all readers quit.
When other writers occupy the buffer, the writer should wait until the writer who occupies the buffer exits.)
