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.
