1. Product Information

1.1 Product Description

The GR-505GGBL5-DR is a receiving module that supports dual frequency and multi-mode. It has built-in highly integrated GNSS receiver chip, supports multi band and multi system cm4f (main frequency 530mhz, 12nm Technology) chip of Third- generation BeiDou Navigation Satellite System (BDS-3). Besides, it is capable of tracking all global civil navigation systems (GPS, GLONASS, BDS, Galileo, QZSS and SBAS) in all bands.

GR-505GGBL5-DR module is based on the state of art BDS-3 architecture, integrating multi-band and multi-system GNSS RF and baseband. This newly designed architecture makes this chip achieve sub-meter level position accuracy without correction data from ground-based augmentation station and higher sensitivity, greater for improved jam resistance and multipath, provide a highly robust service in complicated environment.

GR-505GGBL5-DR module contain MediaTek positioning engine inside, featuring high sensitivity, low power consumption, and fast TTFF.The superior cold start sensitivity allows it to acquire, track, and get position fix autonomously in difficult weak signal environment. The receiver’s superior tracking sensitivity allows continuous position coverage in nearly all outdoor application environments. The high perform ance signal parameter search engine is capable of testing 16 million time-frequency hypotheses per second, offering superior signal acquisition and TTFF speed.
