DGPS introduction DGPS is short for English difference global positioning system, that is, differential global positioning system. A precise known location (reference site)Install the GPS monitoring receiver to calculate the number of distance corrections between the reference station and the GPS satellite. The difference value is usually called PRC (pseudo distance correction value). The reference station

RTK measurement system, generally need to first set up a reference station (reference station), data chain mode plug large radio (antenna power mode, ideal range within 18 km). The base station calculates the current position by receiving a satellite (multi-Star).This involves the setting of the frequency, the baud rate, and the protocol (commonly used tempo protocol, transparent protocol, etc.).These parameters are set to the output to the mobile sta

Recently to do a project on RTK, the use of Rtklib source code based on the transplant, because I in the embedded aspect and RTK is small white, so whether it is embedded communications or RTK have to learn from the beginning. The embedded aspect intends to use the stm32 to carry on the transplant, now already basically grasps the serial port communication method

After receiving the pseudo distance data, the corresponding network processor or locating server can roughly estimate the location of the mobile phone. After necessary corrections are added to the GSM network, the positioning accuracy can be improved. (2) mobile phone GPS Positioning method.
