The MT3188N/C is a high-performance GPS receiver SoC designed to deliver reliable satellite positioning with minimal power consumption. Its ability to support multi-constellation systems like GPS, GLONASS, and QZSS enhances satellite signal availability, ensuring that devices can maintain accurate positioning in a variety of challenging environments, including areas with obstructions that limit the visibility of GPS satellites.

Multi-Constellation Support:

By supporting multiple satellite systems, including GPS, GLONASS, and QZSS, the MT3188N/C ensures robust satellite tracking and reliable positioning. In areas where a single satellite system might not be sufficient due to signal blockage or weak satellite visibility, the chip can switch to other constellations to ensure a constant and accurate location fix.

High Sensitivity:

The MT3188N/C boasts impressive tracking sensitivity of -165 dBm, which is a crucial feature for GPS receivers used in environments with weak signals. Whether you're navigating through urban areas, dense forests, or indoor spaces, the chip can maintain a strong satellite lock and provide accurate positioning.

Low Power Consumption:

One of the key features of the MT3188N/C is its low power consumption, making it ideal for battery-operated devices like wearables, fitness trackers, and location trackers. In sleep mode, the chip consumes less than 1 µA, which is extremely efficient for devices that need to preserve battery life. In active mode, the chip draws about 30 mA, ensuring energy-efficient operation while still providing fast and accurate positioning.

Fast Time to First Fix (TTFF):

The MT3188N/C provides a fast Time to First Fix, meaning it can quickly acquire the GPS signal and lock onto satellites. This is essential for applications where rapid response times are needed, such as real-time tracking or instantaneous navigation. With a cold start TTFF of around 32 seconds and a hot start TTFF of just 0.1 seconds, the chip is capable of quickly determining the position after a device is powered on or when satellite signals are lost.

Positioning Accuracy:

With a horizontal accuracy of 2.5 meters (CEP50) and vertical accuracy of 5 meters, the MT3188N/C offers reliable and precise positioning, which is critical for applications that require accurate location data.
