Product Description
The MTK MT3179N is a compact and efficient GPS receiver chipset developed to provide reliable and accurate location tracking for modern navigation systems. Its high sensitivity allows it to acquire and maintain satellite signals in environments with weak signal availability, such as urban canyons, under tree canopies, or inside vehicles.
The chipset is designed with low power consumption in mind, making it ideal for portable applications such as handheld devices, wearables, and IoT systems. Its power-saving modes, such as sleep and standby, help conserve energy without compromising functionality, ensuring prolonged battery life for devices.
The fast time-to-first-fix (TTFF) capabilities of the MT3179N enhance user experience by enabling quick acquisition of location data, even when starting from a powered-off state. The chipset ensures minimal delay in obtaining position fixes, making it a reliable choice for real-time navigation and tracking applications.
Its multi-satellite tracking feature ensures consistent and accurate positioning data by simultaneously utilizing signals from multiple satellites. This robustness enhances its reliability in challenging environments, ensuring stable performance for automotive navigation systems, outdoor sports devices, and drone applications.
The MT3179N's Assisted GPS (A-GPS) functionality further reduces acquisition times and enhances positioning accuracy, especially in urban areas or during indoor use where satellite signals may be partially obstructed. By leveraging network-based data, the chipset ensures reliable performance in such scenarios.
Its compact design integrates core GPS functionalities into a small footprint, simplifying system integration and enabling its use in space-constrained devices. The chipset is compatible with both active and passive antennas, offering flexibility in device design and ensuring optimal performance across various application scenarios.
The MT3179N supports high update rates of up to 10 Hz, making it suitable for dynamic applications such as automotive navigation, sports tracking, and real-time drone control. Its standardized interfaces, such as UART, enable seamless integration with a variety of microcontrollers and embedded systems.
