The DB4238L5-GN is a receiving module that supports dual-band&multi-mode. It has built-in highly integrated GNSS receiver chip, supports multi band and multi system cm4f (main frequency 350mhz, 22nm Technology) chip of Third- generation BeiDou Navigation Satellite System (BDS-3). Besides,it is capable of tracking all global civil navigation systems (BDS,GPS,Glonass,Galileo,QZSS, IRNSS and SBAS) in all bands.
DB4238L5-GN is based on the state ofart BDS- 3 architecture, integrating multi-band andmulti 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.
DB4238L5-GN module contains BK1662G positioning engine inside, featuring high sensitivity, low power consumption, and fast TTFF. The s
uperior cold start sensitivity allows it to acquire, track, and get position fix autonomously in difficult we ak signal environment. The receiver's superior tracki ng 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
