The M5313 with Communication Modules/GNSS Modules LCC RoHS manufactured by Chinamobile is a versatile communication and navigation module and is suitable for a variety of applications such as intelligent transportation systems (ITS), automation, and other automated positioning and navigation. It can be used in unmanned aerial vehicles (UAVs), electronic control systems, and real-time positioning and navigation applications. The M5313 GNSS Module is a high-performance and cost-effective GPS solution with high sensitivity and coverage for autonomous positioning, navigation, and tracking. It supports multi-constellation satellites, such as GPS, Glonass, Galileo, Beidou, and QZSS, which can achieve fast and accurate positioning. Its built-in antenna can provide faster time-to-first-fix (TTF) and better sensitivity than external antenna. The multi-constellation GNSS receiver provides fast positioning accuracy, stable signal, and rich and flexible output data. It supports broadcasting data from more than 20 satellites with a signal-to-noise ratio (SNR) of 40 dB or higher under antenna feed termination scenarios. The M5313 is also equiped with an internal real-time clock (RTC) which provides accurate event timing under low power. This module is RoHS compliant and certified, meaning it meets all the EU standards for environmental protection. It also has a low current consumption design which helps it to achieve long battery life in mobile applications. The M5313 has passed a number of tests, including temperature resistance, shock-proof, water-proof, and ESD-proof. This ensures not only a durable and reliable performance, but also a high level of stability over time.
