Overview

WTRTK-4G

      A centimeter-level positioning sensor, suitable for high-precision automobile positioning, high-precision mapping, drone positioning and other places;

The internal positioning module adopts U-blox high-precision multi-frequency GNSS positioning module, which can achieve centimeter-level accuracy within seconds, and can simultaneously receive GPS, GLONASS, Galileo and Beidou navigation signals to provide stable and high-precision positioning information;

Data transmission adopts 4G transmission with wide coverage, high-speed and stable signal transmission, which provides stable guarantee for data;

WTRTK-4GB

WTRTK-4GB fixed base station can provide the data information required for differential positioning for WTRTK-4GR and WTRTK-4GA. The fixed base station needs to be connected to the WIT server for high-precision positioning when it is first installed. After positioning, it will need to be fixed at the current position to stably provide the data required for differential positioning for the positioning mobile station and the positioning and directional mobile station;

WTRTK-4GA

WTRTK-4GA adds a multi-frequency GNSS positioning module based on WTRTK-4GR, which makes up for the problem that the GPS must reach a certain ground speed before the heading angle can be obtained. Using two multi-frequency GNSS modules, you can try to obtain the current pointing angle of the two antennas;

WTRTK-4GA also integrates a high-precision IMU sensor, which integrates IMU information when the GPS signal is lost to ensure that stable angle information can be continuously provided when the GPS signal is lost. IMU can also provide stable attitude angle information, showing the current three-axis attitude angle information of the current sensor;

WTRTK-4GR

WTRTK-4GR can connect to 4G network for high-precision centimeter-level positioning. It can be used in conjunction with WRTK-4GB. Differential positioning is performed using the base station data of WTRTK-4GB to obtain centimeter-level positioning accuracy. The real-time positioning information can also be uploaded to the WIT server, and the current location information can be viewed in real time on the computer using WeChat.

At the same time, WTRTK-4GR is compatible with Qianxun services, and you can directly enter the Qianxun account for centimeter-level positioning across the country. When connected to the Qianxun server, data cannot be transmitted to the cloud in real time.

WTRTK-4GR also integrates a high-precision IMU sensor that can be integrated with GPS information to solve the heading angle, and can provide stable heading angle information when the GPS signal is lost. The IMU can also provide stable attitude angle information, showing the current three-axis attitude angle information of the current sensor;
