General Description
The DB2525P-GGB is a receivinge that supports sing le-band&multi-mode. It hasbuilt-in highly integrated GNSS receiver chip, supportsmulti band and multi s ystem cm4f (main frequency350mhz, 22nm Technology) chip of Third-generationBeiDou Navigation Sate llite System (BDS-3). Besides,itis capable of tracking al l global civil navigation systems (BDS,GPS,GLONASS, Galileo,QZSS,and SBAS) in allbands.
DB2525P-GGB module is based on the state of art BDS-3 architecture, integrating Single-band and multi-system GNSS RF and base band. This newly designed architecture makes this single 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.
DB2525P-GGB module contains BK1616P 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 performance signal parameter search engine is capable of testing 16 million time-frequency hypotheses per second, offering superior signal acquisition and TTFF speed.
