Problems solved by technology
At present, the most widely used high-precision positioning technology is RTK (real-time dynamic positioning, Real-Time Kinematic). The key to RTK technology lies in data processing technology and data transmission technology. Usually, some data will be lost during the transmission process of RTK differential data. Therefore, the user data after differential processing still contains a large observation error, resulting in a decrease in positioning accuracy

The invention relates to an RTK differential data transmission method, an RTK differential data transmission device, and a receiver. The method comprises the following steps: acquiring data packets which are received by cellular mobile communication equipment and radio communication equipment from a reference station; judging whether the data packets received by the cellular mobile communication equipment and the data packets received by the radio communication equipment are integral; and if there are integral data packets, analyzing the integral data packets to get RTK differential data. According to the RTK differential data transmission method, the RTK differential data transmission device and the receiver, the cellular mobile communication equipment and the radio communication equipment work together to realize dual-mode transmission of RTK differential data, and RTK differential data is obtained by analyzing only the integral data packets in the data packets received by the cellular mobile communication equipment and the data packets received by the radio communication equipment, and therefore, the stability of RTK differential data is improved, and the positioning accuracy is ensured.
Description
technical field [0001] The invention relates to the field of data communication, in particular to an RTK differential data transmission method and device, and a receiver. Background technique [0002] With the rapid development of satellite positioning technology, people's demand for fast and high-precision location information is also increasing. At present, the most widely used high-precision positioning technology is RTK (real-time dynamic positioning, Real-Time Kinematic). The key to RTK technology lies in data processing technology and data transmission technology. Usually, some data will be lost during the transmission process of RTK differential data. Therefore, the user data after differential processing still contains a large observation error, which leads to a decrease in positioning accuracy. Contents of the invention [0003] Based on this, it is necessary to provide an RTK differential data transmission method, device, and receiver to realize dual-mode transm...
