Gravity: GNSS GPS BeiDou Receiver Module - I2C&UART - DFRobot

What is GNSS?

GNSS stands for Global Navigation Satellite System.
The major GNSS systems include GPS, GLONASS, QZSS and BeiDou. These satellite systems transmit signals toward the Earth, allowing the receiver to determine its position by calculating the propagation time of the signals and the position of the received satellites, thus enabling functions such as positioning and navigation.

What is the Gravity: GNSS GPS BeiDou receiver module?

This GNSS BeiDou positioning module supports multi-satellite joint positioning and provides high-precision, high-speed and stable data such as longitude, latitude, time and altitude. It is suitable for various outdoor positioning scenarios, such as vehicle location, object tracking, weather stations and other outdoor positioning applications.

Multi-System Satellite

This GNSS receiver module uses GNSS positioning system and supports satellite systems such as BeiDou, GPS, GLONASS, QZSS and others. Compared with traditional positioning with a single GPS, multi-system joint positioning increases the number of visible and usable satellites, improving positioning accuracy and speed. It can also ensure stable and high-precision positioning even in complex environments, providing more accurate position data. For example, on smart farms, GPS signals can be disturbed by terrain or vegetation, reducing positioning accuracy. By using multiple GNSS module satellite systems, interference can be reduced and positioning accuracy and speed can be improved, enabling precise management of farmland and crop planting.

Stability

With multi-satellite joint positioning, even if some satellite signals are affected by weather or terrain, other satellites can continue to provide reliable positioning data, ensuring accuracy and reliability. For example, in naval positioning, where weather and sea conditions can vary greatly, positioning accuracy and stability are critical. This product supports the joint positioning of multiple satellite systems, effectively improving accuracy and stability and meeting the requirements for vessel positioning.

Ease of Use

This GNSS receiver module has two types of data output: I2C and UART and is compatible with main control devices such as Arduino, ESP32 and Raspberry Pi. This makes the product flexible enough to adapt to different application scenarios, support multiple interfaces and protocols, and facilitate integration and development by users.
