BKR3-1612

The BKR3-1612 GNSS module, developed by LOCOSYS Technology Inc., is engineered for applications requiring high-precision positioning and exceptional reliability. Built upon an advanced GNSS SoC architecture and incorporating the latest BDS-3 (BeiDou Navigation Satellite System) framework, the module supports multi-band and multi-constellation reception capabilities. It can concurrently track all major global satellite navigation systems, including GPS, GLONASS, Galileo, BEIDOU, QZSS, IRNSS, and SBAS, while offering full support for L1, L2, and L5 triple-band signal reception with centimeter-level RTK positioning accuracy.

At the core of the module is the Beken chip, featuring a 32-bit DSP processor built on 22nm process technology and capable of operating at up to 350MHz. The chip supports up to 200 tracking channels and integrates a dedicated high-performance search engine. It delivers excellent sensitivity across cold start, hot start, and reacquisition modes (from -148dBm to -165dBm), ensuring stable and reliable positioning performance even in challenging signal environments such as dense urban areas or under canopy. The Beken also supports AGPS, RTCM3.X, and offers a maximum update rate of 20Hz, enhancing system responsiveness in dynamic applications.

  LOCOSYS RTK-1612AD-DR uses an Airoha AG3335AD chip, dual-frequency multi-constellation solution GNSS, providing RTK high precision and sensor fusion solution in one. It not only supports GPS, GLONASS, GALILEO, BEIDOU, and QZSS but also has inertial sensors (3-axis accelerometers and 3-axis gyros) to provide an untethered dead reckoning function. In addition to DR, an inertial sensor can detect the vehicular dynamics when it is attached firmly on the vehicle. Consequently, abnormal driving behaviors and the vehicle status can be detected and the alarm status will be enabled to remind the users. No requirement of installation orientation and automatic calibration function make it easy to use. With these features, RTK-1612AD-DR can reduce position errors in multipath environment and continue to work where GNSS signals are poor or not available, such as tunnels and indoor parking lots, as well as deliver seamless navigation.
