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 station (mobile station) to be set. The mobile station sets the same frequency as the base station and other parameters. Then it will receive datum station data to solve the data of the mobile station and other relative position accuracy. The last data that the mobile station outputs to the mobile end is usually output in accordance with the A0183 standard protocol. carry the relevant parameters.

Static acquisition: The data is collected in a single location for more than half an hour, and then put on the PC-side data Solver software to solve a high-precision coordinate.

Data link built-in radio mode: This is also used as a benchmark station, but with built-in radio to search the location of the star, built-in radio antenna (ideal range is within 6 km).

Accuracy: RTK measurement mode accuracy is generally above the centimeter level.

The measurement mode of the mobile side: the location information of the current coordinates is usually collected and stored uniformly.

The Loft mode of mobile: The coordinate data (by line, or road) is usually done on the PC first. Then find the coordinates of this point in the field, and collect coordinates (special cases: surrounding roads, house descriptions, etc.) stored in the list inside the survey library, followed by the processing of data collection. The data collected from the general measurement mode is processed or stored together with the lofting data collected.
