UM980 Module RTK Module High-Precision GNSS GPS Module for Drones Automobiles Surveying Mapping

Description:
AK314-2 type adopts a full-system full-frequency RTK engine and a full-frequency RTK integrated module, which is an ultra-low-cost, low-power, high-performance RTK positioning module. The module's highly reliable carrier phase difference technology can provide real-time centimeter-level positioning accuracy for drones, automobiles, and surveying and mapping users.

The module can be configured as a "mobile station" or a "base station" working mode, through the common view observation between "mobile station" and "base station", using carrier phase difference technology to eliminate ephemeris error, ionospheric error, troposphere error Errors, inter-satellite clock errors and other measurement errors, and finally obtain high-precision positioning results.

When it is configured as a "base station" module, the differential interface outputs RTCM2.x/3.x standard data streams, which are compatible with most commercial mobile stations on the market. At the same time, it provides a reference design of network RTK, which can distribute differential data streams to all mobile stations through the network.

When it is configured as a "mobile station" board, the differential interface supports RTCM2.x/3.x differential data format, which can be connected to the user's existing base stations of other brands or access to the national Beidou ground-based enhancement system.

The static relative positioning accuracy of the module is <1cm/0.4", the medium dynamic relative positioning accuracy is <2cm/0.8", and the output rate is 1~10Hz. It can be used in a variety of scenarios and has a very high cost performance.

- Support Beidou/GPS/Galileo/GLONASS four-mode joint RTK solution, with fast and reliable initialization capability.
- Support up to 50Hz data output to meet the application in the dynamic situation of the drone.
- The module can be flexibly configured as a base station or a mobile station.
- It supports differential positioning and vector attitude measurement modes, and can output high-precision positioning and orientation results at the same time.
- Built-in four-arm helix antenna combination, with light weight, high gain, high precision and strong anti-interference ability.
- Adopt industrial-grade low-noise radio frequency circuit, strong anti-multipath suppression.

Typical Application:
1. High precision positioning in short and medium distances: In the high-precision positioning application of short and medium distance (<3km), the module cooperates with data transmission modules to form a complete set of high-precision positioning system with a small number of external circuits, which is suitable for the application of a large number of mobile stations in a small range. At the same time, the module is fully compatible with other automatic flight control systems such as for Pixhawk and APM.

2. Medium and long-distance high-precision positioning: In the application of high-precision positioning at medium and long distances (< 10km), common data transmission modules are difficult to provide reliable differential data connections, and the problem of packet loss is serious. For this purpose, we offer solutions based on 4G networks. The reference station sends differential data over the wired network to the server and is cached by the server. The mobile station accesses the server through the 4G network and obtains differential data. This solution can greatly expand the role area of the base station, and the mobile station equipped with a 4G network card can transmit the positioning results back to the designated server at the same time.

3. High-precision positioning without reference station: In high-precision positioning applications without reference stations, this module needs to cooperate with the 4G communication module to obtain differential data. We provide differential data sources, where users can obtain high-precision positioning results without deploying a base station.
