Product Description
The MTK MT3116N is a high-performance GPS chipset tailored for applications demanding accurate, reliable, and energy-efficient navigation. Its advanced high sensitivity capabilities allow it to acquire and maintain satellite signals in environments with weak GPS signals, such as urban canyons, under dense foliage, or near indoor windows.
The chipset's low power consumption makes it particularly suitable for portable and IoT devices, extending operational life for battery-powered applications like wearables, asset trackers, and fitness devices. Its integrated power-saving modes enable efficient energy management, ensuring prolonged use without frequent recharging.
The MT3116N delivers fast TTFF, enabling quick and reliable satellite acquisition for real-time applications. Whether starting cold, warm, or hot, the chipset ensures minimal delays in obtaining position fixes, enhancing user experiences in scenarios like turn-by-turn navigation or emergency tracking.
With the ability to track up to 22 satellites simultaneously, the MT3116N provides robust and consistent positioning data, even in challenging conditions. The inclusion of A-GPS functionality further improves its performance, especially in urban environments with limited satellite visibility. By leveraging network assistance, it reduces acquisition times and improves location accuracy.
The chipset’s compact design integrates core GPS functionalities into a small package, simplifying system integration and reducing overall device size and cost. Its antenna flexibility allows manufacturers to optimize signal reception by using active or passive antennas, based on the specific application requirements.
The high update rate of up to 10 Hz ensures smooth tracking for dynamic applications such as sports tracking, drone navigation, and automotive systems. Its standard UART interface enables seamless communication with a wide range of embedded systems and microcontrollers, ensuring compatibility across various platforms.
