General Description
DelinComm DB1818-GGB is a receiving module that supports single-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,and SBAS) in all bands.
DB1818-GGB odule is based on thestate of art BD S -3 architecture, integrating Single-bandand multisystem 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.
DB1818-GGB module contains BK1661 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.
