The MT3326N/B is a highly versatile GPS receiver SoC that is engineered to provide high-performance positioning while keeping power consumption low. Its multi-constellation support, which includes GPS, GLONASS, BeiDou, and QZSS, ensures that the receiver can always find and lock onto a sufficient number of satellites to provide accurate positioning data. This feature significantly enhances its performance, especially in challenging environments where fewer satellites might be visible, such as urban areas or dense forests.

Multi-Constellation Support:

The MT3326N/B is capable of tracking signals from multiple satellite constellations simultaneously. This feature boosts the receiver's reliability and accuracy by providing access to a larger pool of satellites. It is especially beneficial in areas where one satellite system (e.g., GPS) might not be sufficient due to obstruction or signal interference. With BeiDou, GLONASS, and QZSS support, the MT3326N/B increases the probability of maintaining an accurate position fix even in low-visibility environments.

High Sensitivity:

One of the standout features of the MT3326N/B is its ability to track weak signals as low as -165 dBm, which is crucial in challenging environments. Whether you're inside a building, in a forest, or in a densely populated city, the MT3326N/B can still provide accurate positioning data by maintaining a strong lock on satellites despite weaker signals.

Low Power Consumption:

The MT3326N/B is designed with low power consumption in mind, making it ideal for devices that rely on battery power. In active mode, the chip consumes about 30 mA, which is typical for most GPS receivers, while in sleep mode, it draws less than 1 µA. This low power design ensures that the MT3326N/B can be used in battery-operated devices like fitness trackers, smartwatches, and location-tracking devices, without significantly affecting their battery life.

Fast Time to First Fix (TTFF):

The MT3326N/B achieves fast TTFF, meaning that it can acquire satellite signals and determine a location quickly. It is optimized for both cold start and warm start conditions, providing fast lock-on times even after the device has been powered off or if the signal has been lost. With a cold start TTFF of around 32 seconds, and a hot start of just 0.1 seconds, the MT3326N/B ensures that GPS-based applications can begin functioning quickly.

Position Accuracy:

The chip offers high-precision positioning with a horizontal accuracy of 2.5 meters and vertical accuracy of 5 meters. This level of accuracy makes the MT3326N/B suitable for a wide variety of GPS-based applications, including navigation, tracking, location-based services, and geo-fencing.
