Product Description
The MTK MT3336N is a cutting-edge GPS chip designed to meet the growing demand for precise and energy-efficient location-based services across a range of consumer and industrial devices. Its integration of multiple GNSS constellations — including GPS, GLONASS, QZSS, and BeiDou — ensures it offers superior coverage and better positioning accuracy than traditional single-constellation GPS systems. This feature helps users maintain a stable GPS fix, even in challenging environments where signals might be obstructed or weak.
At the core of the MT3336's performance is its high sensitivity. It can detect and maintain a connection to GPS satellites even in environments with weak signals, such as in cities with tall buildings, dense urban areas, or places with heavy tree cover. The chip's sensitivity (-162 dBm) allows it to deliver accurate positioning even when GPS signals are not optimal, providing consistent and reliable performance across diverse conditions.
Another important feature of the MT3336 is its low power consumption, making it ideal for portable and battery-powered applications. The chip consumes only 30-40 mA during active GPS operation, and in sleep or idle modes, its power consumption is significantly reduced. This allows devices like wearables, mobile phones, and personal navigation devices to extend battery life while still providing precise location tracking. Its low voltage operation (2.7V to 3.6V) further enhances its compatibility with a range of low-power devices.
The Time-to-First-Fix (TTFF) performance is another highlight of the MT3336. Whether the device is powered on for the first time or after a period of inactivity, the chip quickly establishes a connection with the GPS satellites and computes the user’s location. This rapid acquisition is made possible by its built-in algorithms, which reduce the cold start time and allow it to lock onto satellites faster.
In addition to the basic GPS functionality, the MT3336 also supports Assisted GPS (A-GPS). This technology improves TTFF and positioning accuracy, particularly in challenging environments where satellite visibility is limited. By utilizing information from nearby cell towers or Wi-Fi networks, A-GPS helps provide faster position fixes, reducing the time it takes to get a reliable location fix, even in areas with weak satellite signals.
The MT3336 is a highly integrated chip that combines multiple GPS processing elements into a single package. This integration not only helps reduce the device’s overall size and cost but also enhances reliability and performance. Its support for both UART and I2C communication interfaces makes it versatile for use in a variety of applications. It can be easily interfaced with microcontrollers, embedded systems, and other devices, making it suitable for a wide range of consumer and industrial GPS-based applications.
The MT3336’s compact design makes it suitable for space-constrained applications, while its multi-constellation support ensures users can depend on it for accurate location data no matter where they are in the world. It provides an ideal solution for devices such as portable GPS units, smartphones, fitness trackers, automotive navigation systems, and other IoT-based products that rely on real-time location services.
