specific Embodiment approach 1

[0030] Specific implementation mode one: combine figure 1 To describe this embodiment, the server-side RTK solution positioning system provided in this embodiment includes: a rover station, a reference station, and a server;

[0031] The mobile station includes an active antenna, a positioning module, an embedded processor and a communication module; the server includes a data distribution component, a solution pool and a database, and the data distribution component, the solution pool and the database can be in the same or different Run separately under the server, so as to balance the load after the scale is expanded in the later stage;

[0032] The active antenna is used to receive observation signals from navigation satellites (i.e. radio frequency signals from navigation satellites), and transmit them to the positioning module in one direction;

[0033] The positioning module is used to convert the observation signals from navigation satellites into formats such as RTCM ...

specific Embodiment approach 2

[0041] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the mobile station further includes a power supply module; the power supply module provides power for each module of the mobile station. In this embodiment, the power supply module includes such as Figure 4 The wireless charging part shown (XC9236 chip) and as Figure 5 The power management part shown (IP5305 chip); among them, the power management part uses 4 LEDs to display the battery power, when the current is less than 45mA and unloaded for 32 seconds, it will enter the sleep mode; when the current is greater than 45mA, it will be woken up; Figure 5 Input from pin 1 Vin of IP5305 chip, output from pin 8 Vout; Figure 4 The input of pin 1 VIN of the XC9236 chip comes from the output of pin 8 of the IP5305 chip, and the PFM / PWM automatic mode is used to convert the VIN from Figure 4 The power input of pin 1 VIN is adjusted from 5V to 3.3V.

specific Embodiment approach 3

[0043] Embodiment 3: This embodiment is different from Embodiment 2 in that the power supply module of the mobile station is charged in a wireless charging manner.

[0044] Other steps and parameters are the same as in the second embodiment.

Abstract

The invention provides an RTK resolving positioning system and method of a server, and belongs to the technical field of high-precision positioning. The system comprises flow stations, a reference station and a server; each flow station comprises an active antenna, a positioning module, an embedded processor and a communication module; and the server comprises a data distribution assembly, a resolving pool and a database. The method comprises that the data distribution assembly receives a configuration file and correction data from the reference station and converted observation information from the flow stations, the received data is forwarded to the corresponding resolving pool according to an ID of the flow station, and a positioning result returned from the resolving pool is sent to the corresponding flow station and database; and if the quality of a satellite signal is low, or connection with the reference station is lost, the server requests the flow station to upload NMEA information as a resolving result. The problems that a present flow station of RTK positioning technology is large in size and high in power consumption are solved. The system and method can be applied to RTK positioning technology.

Description

technical field [0001] The invention relates to an RTK solution and positioning system and a positioning method, and belongs to the technical field of high-precision positioning. Background technique [0002] RTK (Real-time kinematic, real-time dynamic) carrier phase difference technology is a kind of satellite technology such as Beidou and GPS. Three-dimensional positioning results, and achieve centimeter-level accuracy. In the traditional RTK positioning process, the differential data (pseudorange observation value, phase observation value, ephemeris data) of the reference station is transmitted to the rover through the network, and the rover uses the transmitted reference station data and its own observation data to carry out RTK solution to obtain its own high-precision position. Since the calculation process is performed in the mobile station, in order to support the calculation process, the hardware design of the mobile station must be complex, large in size, and pow...
