Ultra-compact GNSS module with multi-constellation positioning
The ME3AGR01 is a compact GNSS navigation and positioning module designed to deliver reliable performance across diverse applications. Supporting multi-constellation reception, it enables simultaneous tracking of BDS, GPS, GLONASS, GALILEO, and QZSS, ensuring precise and stable positioning through multi-system integration.
Built with a high-sensitivity, low-power GNSS chip and integrated RF components, the module combines strong anti-interference capability with excellent power efficiency. Its standard SMD industrial-grade design, manufactured with RoHS compliance, measures only 6 × 8 × 2.0 mm, making it ideal for space-constrained devices.
With its combination of high performance, compact size, and low power consumption, the ME3AGR01 is well-suited for a wide range of applications, including wearable devices, vehicle navigation systems, trackers, dashcams, and OBD solutions.
