Product Description
The MT3339 can achieve a remarkable -165 dBm tracking sensitivity, ensuring reliable performance even in challenging environments, such as dense urban areas.
The chip features extremely low continuous tracking power consumption of just 3 mA, making it ideal for battery-operated devices. MediaTek’s AlwaysLocate™ technology further optimizes power usage by adjusting the tracking rate based on movement.
In addition to GPS, the MT3339 supports multiple Global Navigation Satellite Systems (GNSS), including QZSS (Quasi-Zenith Satellite System) and SBAS (Satellite-Based Augmentation Systems), enhancing accuracy and availability.
The chip is designed to handle both indoor and outdoor environments, offering multi-path detection and compensation for better positioning accuracy in complex scenarios.
Application Areas:
Portable Devices: Thanks to its small size (4.3mm x 4.3mm package) and low BOM (bill of materials) requirements, it is well-suited for portable gadgets such as wearables, handheld devices, and cameras.
Automotive Systems: It can be used in vehicle navigation systems and tracking applications, providing reliable positioning for in-car navigation and fleet management.
Industrial Applications: Its robust performance and small size make it an excellent choice for drones, industrial trackers, and other equipment requiring precise positioning in various environments.
