Specification parameters
MT3337V/B is a high-performance GPS receiver designed to meet the needs of modern navigation and location-based services. With its ability to track multiple satellite constellations, it provides robust and accurate positioning, even in areas with challenging signal reception conditions.
GPS and Multi-Constellation Support:
The chip supports GPS, GLONASS, BeiDou, and QZSS satellite systems. This multi-constellation support improves global positioning accuracy and reliability. By utilizing multiple satellite systems, the MT3337V/B can provide better signal coverage and reduce the likelihood of losing a GPS lock, especially in difficult environments such as urban areas with tall buildings or indoors.
High Sensitivity and Fast Position Fixing:
One of the standout features of the MT3337V/B is its high sensitivity. With a tracking sensitivity of -165 dBm, it can maintain GPS positioning even in weak signal environments. Whether the device is in a densely packed city with tall buildings, in a tunnel, or under thick tree cover, the MT3337V/B can still provide accurate positioning. Moreover, its quick position acquisition and hot start capabilities ensure that the GPS receiver locks onto satellites quickly, minimizing the time needed to acquire a position fix when turning on the device.
Low Power Consumption:
Power consumption is a critical factor in portable devices like smartphones, wearables, and GPS trackers. The MT3337V/B excels in this area, offering ultra-low power consumption, especially when in sleep mode. It consumes only 30 mA in active mode, allowing for long battery life in mobile applications. In sleep mode, the current consumption drops to less than 1 µA, making it ideal for always-on tracking in battery-powered devices.
Interfaces and Integration:
The MT3337V/B supports various communication interfaces like UART, SPI, and I2C. This makes it compatible with a wide range of host devices, including smartphones, IoT devices, and automotive systems. The UART interface is typically used for simple communication with host processors, while SPI offers higher data transfer speeds. I2C is useful for connecting additional sensors or devices in low-power scenarios, making the MT3337V/B highly versatile for different applications.
Accurate and Reliable Positioning:
In terms of accuracy, the MT3337V/B provides horizontal accuracy of 2.5 meters (CEP50), which is suitable for most navigation and location-based applications. The vertical accuracy is approximately 5 meters, ensuring reliable 3D positioning. Whether used in outdoor navigation, fitness tracking, or automotive navigation systems, the MT3337V/B ensures precise location data.
