Please teach seniors a few rtk measurement problems

1, the first thing to be clear is that RTK measurements must have a reference station data can be resolved to a fixed solution. There are many different methods of base station data transmission, the more commonly used is the data radio transmission and cell phone signal transmission on the Internet, you said the first way should be their own in the known points to set up the base station, the use of data radio transmission of differential signals, the second way may use the CORS system to provide the differential signal of the base station, with the mobile network of the cell phone card to receive.

2, GPS RTK measurement specifications provide that, in the fragmentation point measurement and sampling before, must go to a known point to calibrate, meet the specification requirements before continuing to administer the measurement. If it is to an unknown measurement area, you also need at least two known points to calculate the four-parameter or seven-parameter conversion parameters to be measured.
