1. Product Information
1.1 Product Description
The GT-502GGB/GT-502MGGB features multi-constellation and ultra-low power consumption, with a highly integrated GNSS receiver chip built in to support multi-system Cortex®-M4F.
The GT-502GGB/GT-502MGGB supports concurrent reception of four GNSS (GPS/QZSS, GLONASS, BeiDou, and Galileo) and augmentation systems (SBAS). The multi-constellation enables the module to achieve an accuracy of approximately 1.5M and stable GNSS performance especially in challenging environments.
Applications
 Automotive Navigation
