Summary of rtklib dynamic positioning function data processing
no vote
Precise GPS dynamic measurement adopts carrier phase difference technology. Its standard measurement mode is that one GPS receiver is placed at a known point as a reference station for static measurement, and the other GPS receiver is placed on a carrier as a mobile station for dynamic measurement. Two receivers observe the same satellite synchronously, and then combine the observations of the two GPS receivers to obtain the coordinates and velocity of the mobile station relative to the reference station. This paper mainly introduces the process of using rtklib to realize precise dynamic positioning. The process includes reading observation files and navigation files, calculating the location of reference station, solving the location of mobile station, outputting the operation results, etc. it helps GNSS developers to quickly master rtklib

How to use DataGridView control to realize data transfer between different forms
no vote
Problem: data transfer between datagridviews of different forms is realized by data binding (assuming that the data in form2 is to be transferred to form1): 1. Define a class to store DataGridView data; 2. Define DataGridView data list in form2 and store the data; 3. Define a function to return bound data in from2 to return bound data; 4 Initialize column in form1; 5. Start form2 in form1, and then transfer the binding data returned from from2 to DataGridView in form1 to complete the data transfer.
