Introduction

This high-performance positioning and navigation module adopts a new navigation-integrated SOC single-chip technology, capable of meeting the demands of high-precision positioning and timing applications. It features high integration, high performance, low power consumption, and compact size, while supporting both BeiDou-2 and BeiDou-3 signals. The module series offers three common package types and is compatible with the software and hardware interfaces of GNSS modules from other manufacturers. Based on proprietary rapid satellite acquisition technology, the module can quickly receive signals from a large number of visible satellites, enabling fast and accurate positioning with significantly improved performance in complex environments. The integrated high-performance embedded CPU supports a position update rate of up to 10 Hz, making it suitable for high-dynamic applications sensitive to positioning latency. The module also integrates proprietary anti-jamming hardware acceleration circuitry for rapid detection and suppression of RF interference. Certain models support powering the RTC and backup RAM via a coin cell battery or supercapacitor to reduce Time-To-First-Fix (TTFF). The module supports UART and GPIO interfaces for peripheral connectivity.
