The MT3117N/B is a high-performance GPS receiver SoC that combines multi-constellation satellite tracking, low power consumption, and high sensitivity to deliver reliable and accurate positioning for a variety of devices. It is well-suited for applications that require real-time tracking, navigation, and location-based services (LBS).

Multi-Constellation Support:

The MT3117N/B is compatible with multiple satellite systems: GPS, GLONASS, and QZSS. This multi-constellation support improves the satellite availability and overall positioning reliability. It ensures that the chip can find and lock onto a sufficient number of satellites in challenging conditions where a single system might not provide a reliable fix, such as in urban canyons or under dense tree cover. With a higher number of satellites available, the chip can provide more accurate and robust location data.

High Sensitivity:

With an impressive tracking sensitivity of -165 dBm, the MT3117N/B excels in maintaining a satellite lock in areas with weak signals. Whether the device is operating in indoor spaces, in a car surrounded by tall buildings, or under a dense forest canopy, the chip can still track satellites accurately, ensuring that the device provides reliable location data even in less-than-ideal conditions.

Low Power Consumption:

The MT3117N/B is specifically designed to minimize power consumption, making it suitable for battery-powered devices like wearables, fitness trackers, and location-based trackers. In sleep mode, it consumes less than 1 µA, which helps extend battery life significantly. When active, the chip uses around 30 mA, which is typical for GPS receivers but still power-efficient for continuous usage in mobile devices.

Fast Time to First Fix (TTFF):

The MT3117N/B delivers a quick TTFF, ensuring that devices powered by the chip can quickly acquire satellite signals and compute the location. The cold start TTFF is approximately 32 seconds, but if the device has a previous satellite position stored (warm or hot start), the TTFF can be as fast as 1-2 seconds or even 0.1 seconds, respectively. This rapid lock-on time is especially important in applications that require instant location determination after powering up or resuming from power-saving modes.
