The BDS single Beidou satellite positioning module is a hardware device specially designed to receive and process signals from the Chinese Beidou Navigation Satellite System (BDS) to provide Position, Velocity, and Time (PVT) information.

Core Definition

Single System Support: Only supports Beidou satellite signals (BDS) without relying on other navigation systems such as GPS or GLONASS, suitable for applications emphasizing autonomous control.

Modular Design: Typically exists in the form of integrated chips or boards, which can connect to main control devices (such as vehicle terminals or drones) via serial ports (such as UART), I2C, and other interfaces.

Main Funciones

Positioning: Calculates longitude, latitude, and altitude coordinates via Beidou satellite signals.

Timing: Provides high-precision time synchronization (Beidou time) for telecommunications, power supply, and other fields.

Speed Measurement: Calculates the real-time speed of moving objects.

Data Output: Usually supports NMEA-0183 protocol (such as GGA and RMC statements) or custom formats.

Typical application scenarios

In-vehicle navigation: Vehicle trajectory monitoring, electronic fences, autonomous driving (combined with high-precision positioning).

Drones: Precise route planning, agricultural protection, surveying and remote sensing.

Smart wearables: Location watches for children/elderly, exercise trajectory recording.

Precision agriculture: Autonomous driving for agricultural machinery, variable fertilization (dependent on RTK centimeter-level positioning).

The BDS Beidou satellite positioning module is a key hardware platform of China's Beidou system, widely used in both military and civilian fields. According to requirements, one can choose either a pure Beidou module (independently controllable) or a multi-mode combination module (global high precision). In the future, with the improvement of Beidou-3, its positioning capabilities and application scenarios will further expand. The EBYTE BDS single Beidou satellite positioning and navigation module utilizes signals from Beidou-2 and Beidou-3 satellites to provide high-precision positioning, navigation, and time synchronization services. Due to its high integration, high performance, low power consumption, and compact size, it is widely used in automotive navigation, wearable devices, mobile phones, IoT devices, and drones.
