MT2503's dual-star positioning + GPRS baseband tracking and positioning solution


The biggest feature of this solution is compatible with dual-star positioning (GPS and BeiDou) + GPRS baseband tracking to achieve the industry's most accurate positioning, easier to track the trajectory, and easier to distinguish trajectory traffic. This solution is suitable for wearable devices such as smart shoes and smart bracelets, and is more suitable for updating product definitions. Its high level of integration allows designers to have more space and more choice of application scenarios for elements such as volume and thickness.
