LinkTrack高精度定位系统

Introduction

LinkTrack is a PNTC (positioning, navigation, timing and communication) local positioning system based on UWB technology. It supports 1D, 2D and 3D positioning, 1D and 2D typical positioning accuracy is 10cm, and 3D typical positioning accuracy is 30cm; it also supports 40 tags and 120 base station positioning. Support distributed ranging and data transmission, realize cluster formation without geographical restrictions; support pure data transmission mode, bandwidth up to 3Mbps.

One-Key Calibration

For the convenience of users, only needs to send the command to any anchor or console in the system, the system will automatically complete the calibration of the anchor and save the configuration. It is really easy to deploy and get started quickly.

Fake GPS

The LinkTrack UWB positioning system supports NMEA-0183 protocol, you can directly replaces the GPS in you target with the positioning tag. Without any secondary development, you can obtain higher positioning accuracy and refresh frequency than GPS.

ROS Support

Connect to any positioning node, run LinkTrack ROS node, you can subscribe to real-time positioning information, without processing the underlying communication and data analysis, making it possible for ROS developers to achieve high-precision positioning and navigation of robots quickly.

Intelligent Two-way Broadcast

LP Mode

LP Mode supports positioning, navigation, time service and communication working at the same time. The roles are divided into tags, anchors and consoles.

The tag measures the distance to the anchor and solves the coordinates and outputs it in real time through the communication interface, and the navigation function can be realized after connecting to the robot, UAV and other carriers. The anchor and console synchronously output all tag positioning information in real time, and access the terminal display platform to realize the positioning (monitoring) function. At the same time of positioning, the tag and anchor/console support two-way data transmission communication to realize the communication function. Each tags output contains a unified system time for synchronous timing. Typical 1 and 2 dimensional positioning accuracy 10cm, typical 3rd dimensional positioning accuracy 30cm; When the positioning frequency is 200Hz, the delay is only 5ms; The anchor capacity is up to 120, and the tag capacity is open by default to 200.

DR Mode

DR Mode supports the integration of ranging, timing and communication, with only one role of node.

Each node measures the distance to other nodes in real time, and receives data 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 contains a unified system time to achieve synchronous time service. The typical ranging accuracy is 10cm, and when the refresh frequency is up to 200Hz, the delay is only 5ms; at the 10Hz output, the node capacity is up to 50.

DT Mode

DT Mode supports three sub-modes of intelligent communication, two-way communication and broadcast communication. There are two roles of master and slave in this mode.

Under DT Mode, high-speed, low-latency wireless data transmission can be achieved. The data transmission bandwidth is up to 3Mbps, and the delay is less than 0.5ms.
