One-click positioning
For the convenience of users, only need to send [coordinate measurement] command to any base station or console in the system, the system will automatically complete the base station calibration work and save the configuration, truly easy deployment and quick start.
Pseudo GPS positioning
The LinkTrack UWB positioning system supports NMEA-0183 protocol output and uses positioning tags to directly replace the GPS of the original object to be located. Without any secondary development, it can obtain higher positioning accuracy and refresh frequency than GPS.
ROS support
Connect to any positioning node and run the LinkTrack ROS open-source driver package to subscribe to real-time positioning information. There is no need to deal with underlying communication and data analysis, making it possible for ROS developers to achieve high-precision positioning and navigation of robots in a short time.
LP Mode|Local Positioning Mode
After the tag measures the distance to the base station and calculates the coordinates, it is output in real-time through the communication interface, and the navigation function can be realized after being connected to carriers such as robots and drones. The base station and console simultaneously output all tag positioning information in real-time, and the terminal display platform is connected to realize the positioning (monitoring) function. While positioning, the tag and the base station/console support two-way digital communication to realize the communication function. Each label output contains the unified system time to realize the synchronous timing function. The typical 1- and 2-dimensional positioning accuracy is 10cm, and the typical 3-dimensional positioning accuracy is 30cm; when the positioning frequency is 200Hz, the delay is only 5ms; the base station capacity is up to 120, and the tag capacity is opened by default 40, and more applications are required.
DR Mode|Distributed Ranging Mode
Each node measures the distance to other nodes in real-time and receives data transmitted from other nodes. At the same time, it can also transmit its own data to other nodes through the communication interface to achieve ranging and communication functions. The output data content of each node includes a unified system of time to realize the synchronization timing function. The typical ranging accuracy is 10cm, and when the refresh frequency is up to 200Hz, the delay is only 5ms; under 10Hz output, the node capacity is up to 50.
DT Mode|Data Transmission Mode
High-speed, low-latency wireless data transmission can be achieved in DT Mode. The data transmission bandwidth is up to 3Mbps, and the delay is less than 0.5ms.
