Product Description
The MTK MT3328N is a versatile and high-performance GPS receiver designed to cater to a wide range of applications that rely on accurate, real-time location tracking. With support for multiple GNSS constellations, including GPS, GLONASS, QZSS, and BeiDou, the MT3328N provides excellent satellite coverage and positioning accuracy. This multi-GNSS support ensures that the chip can maintain a stable position even in challenging environments where traditional GPS systems might struggle to get a fix.
One of the standout features of the MT3328N is its high sensitivity. With a cold start sensitivity of -148 dBm and a hot start sensitivity of -160 dBm, the chip is highly capable of acquiring GPS signals even in areas where other GPS receivers might fail. Whether inside buildings, in dense urban areas with tall buildings, or under heavy foliage, the MT3328N can still obtain and maintain a reliable GPS signal, which is crucial for applications that require continuous tracking.
In addition to its high sensitivity, the MT3328N is designed to minimize power consumption, making it suitable for battery-operated devices. With an operating current of around 30-40 mA and the ability to enter power-saving modes, the MT3328P is ideal for portable devices where battery life is a key concern. Whether in wearable devices, portable GPS units, or IoT systems, the chip's low-power operation helps to extend battery life, ensuring that devices can run for longer periods without frequent recharging.
The MT3328N also supports A-GPS, which enhances the time-to-first-fix (TTFF) by utilizing external network data (such as Wi-Fi or cellular information). This is particularly useful in scenarios where the satellite signal is weak or unavailable, such as indoors or in urban environments. By leveraging external data sources, the chip can quickly obtain a fix and reduce the time required to start tracking the user’s location.
With an update rate of up to 10 Hz, the MT3328N provides frequent and accurate location updates, which is essential for dynamic applications that require real-time tracking. This feature is particularly useful in automotive navigation systems, sports tracking devices, and other applications where fast and accurate position data is required.
The chip's compact design allows for easy integration into small, space-constrained devices, and its integration of all essential GPS components into a single chip reduces the need for additional external components. This simplicity and cost-effectiveness make the MT3328N a popular choice for embedded systems and consumer electronics.
