The RTKBS2000 Series RTK High-Precision Positioning Base Station, launched by Guoxin Longxin, is a customized integrated communication and positioning differential base station. It integrates three core functions: Beidou positioning base station, wireless private network WMAN system, and wireless public network 4G/5G (customization required). The device features flexible networking methods, high satellite positioning accuracy, small size, light weight, low power consumption and other technical characteristics. The RTKBS2000 Base Station can provide satellite positioning differential data for RTK positioning clients (ICSE1000 Series Communication and Sensing Integrated System), which serves as the data benchmark for high-precision positioning and helps the communication-sensing integrated system achieve centimeter-level high-precision positioning.
The RTKBS2000 Series RTK Base Station System is a customized product. The basic version supports only the iMAX Wireless Metropolitan Area Network (WMAN) private network for wireless access, while the upgraded version not only supports the iMAX Wireless MAN private network but also provides LTE/5G interfaces. For local connection, it is equipped with 3-4 Ethernet interfaces, enabling the access and convergence of multiple services (e.g., video and control information). The iMAX Wireless MAN private network can meet the private network access needs of intelligent control scenarios with higher requirements for stability, reliability and security; the LTE/5G interfaces support Internet access or remote Virtual Private Network (VPN) access. For customers with high data security requirements or those operating in project areas without differential station service coverage, deploying a self-built RTK base station with this device is the optimal solution.
To meet the requirements for tightness, sealing performance and reliability of connections in mobile scenarios such as vehicle-mounted, shipborne and airborne applications, all interfaces of the RTKBS2000 Series RTK Base Station System adopt aviation connector design. The device is suitable for harsh industrial environments, with IP67 protection rating and operating temperature compliant with industrial wide-temperature standards. Guoxin Longxin provides free API development interfaces and related documentation to third-party main engine manufacturers, automobile manufacturers and software-hardware integrators, thus significantly reducing the development cycle and R&D costs of partners.

How to determine whether a mobile terminal is in the high-precision RTK differential positioning state?
The RTKBS2000 Base Station is interconnected with the ICSE1000 Communication and Sensing Integrated System configured on the mobile terminal via the iMAX Wireless Metropolitan Area Network (WMAN) private network. The RTKBS2000 RTK Base Station System transmits Beidou satellite positioning data to the ICSE1000 Communication and Sensing Integrated System through the network. When both systems access more than 4 identical Beidou satellites simultaneously, centimeter-level high-precision positioning can be achieved.
Positioning data can be viewed via the ICSE1000 Communication and Sensing Integrated System. The output data content includes: positioning and orientation navigation messages, such as GNSS and INS pose and velocity messages, timing information, azimuth, and the ID of the base station that is the source of the received differential data during RTK operation; it also includes satellite status (number of visible satellites, satellite identification numbers, elevation angles, azimuth angles, and Signal-to-Noise Ratio (SNR) values). The data format is shown in the figure below:
Note: In the data string “E, 4, 39” shown in the figure above, the value “4” indicates that the RTK solution status of the ICSE1000 Series Communication and Sensing Integrated System is Fixed Solution. This means the system has received differential data from the RTKBS2000 RTK Base Station and is capable of positioning. The positioning accuracy can reach a centimeter-level high precision of 1.0 cm + 1 ppm (horizontal) and 1.5 cm + 1 ppm (vertical).
Typical Applications
The RTKBS2000 Series RTK Base Stations are widely used in high-precision positioning scenarios and are often deployed in conjunction with the ICSE1000 Series Communication and Sensing Integrated Systems. Typical applications include but are not limited to the following scenarios:
- Vehicle Intelligent Control and Management: Unmanned driving, remote control, dispatching and management of mobile vehicles, including mining trucks, heavy-duty trucks, cranes, freight trucks, sweepers, fire engines, ambulances, official vehicles, buses, forklifts, warehouse cleaning machinery and other types of vehicles;
- Heavy Machinery Intelligent Control: Intelligent management of large-scale hoisting machinery (yard gantry cranes, quay cranes, overhead cranes, gantry cranes, etc.), including anti-collision, unmanned operation or intelligent control digital twin systems;
- Unmanned Equipment Centralized Control: Centralized management and control systems for large-scale robots and unmanned equipment (AGV/IGV/RGV, unmanned logistics vehicles, unmanned sweepers, unmanned intelligent agricultural machinery, autonomous taxis, etc.);
- Vessel Intelligent Management: Networking, dispatching and centralized management of vessels (especially unmanned vessels), including AIS, anti-collision, load limitation management, etc.;
- Other Applications: Leasing management of engineering machinery such as tower cranes; dispatching management of trains and rail transit; operation safety management of special large-scale mechanical equipment; management and remote control of low-altitude aircraft such as helicopters, airships, unmanned aerial vehicles (UAVs) and eVTOLs.
