Industrial-Grade Satellite Positioning Board for Multi-Scenario Use
The DALANG AK967 Circuit Board is equipped with the UBX-M9140-KB module, fully compatible with four major satellite systems (GPS, Beidou, GLONASS, Galileo). Adopting an industrial-grade design and advanced algorithms, it operates stably in harsh temperatures ranging from -40℃ to +85℃, making it a reliable positioning choice for IoT, precision agriculture, industrial monitoring, and other fields.
Strong Signal Reception with Concurrent Multi-Constellation
AK967 can receive signals from four satellite navigation systems simultaneously. Combined with a SAW filter and Low Noise Amplifier (LNA), it not only suppresses RF interference but also improves positioning accuracy and availability in complex environments such as urban high-rises and mountainous obstructions. It also has a built-in deception detection algorithm to ensure the authenticity and security of positioning data.
High Real-Time Adaptability for Dynamic Scenarios
This board offers a maximum positioning update frequency of 25Hz, with a horizontal positioning accuracy (with SBAS) of up to 1.5 meters. Its low-latency feature is suitable for dynamic scenarios such as UAVs and autonomous driving, meeting the real-time requirements of system control.
Wide Temperature Range and High Scalability Design
AK967 operates in a temperature range of -40℃ to +85℃, enabling stable operation in high/low temperature and strong electromagnetic interference environments. It is compatible with the M9 series for easy function expansion.
Product Advantages
Multi-System Compatibility + Anti-Interference & Anti-Deception
Access to four satellite systems simultaneously, paired with hardware filtering and malicious signal detection, ensures accurate and secure positioning in complex environments.
High Update Rate + Meter-Level Accuracy
25Hz update frequency adapts to dynamic scenarios; 1.5m horizontal accuracy (with SBAS) meets the needs of smart cities, precision agriculture, etc.
Wide-Temperature Industrial Stability
Operating temperature of -40℃ to +85℃, suitable for long-term operation in harsh scenarios such as outdoor and industrial environments.
