The BCM47765 from Broadcom is a GNSS SoC (System on Chip) that supports GPS, GLONASS, NAVIC, BeiDou, Galileo, SBAS, and QZSS in both the L1/ B1/E1 and L5/E5a/B2a frequency bands. This SoC is integrated with a sensor hub microcontroller which has a dual-processor architecture (Arm CM4+CM0) that ensures each task is handled in the most power-efficient manner. It has internal LNAs and adjustable gain to support external LNA operation with a noise figure better than 3.5 dB and supports HDGPS (High-Definition GPS) technology.
The device exhibits Robust anti-spoofing behavior through hardware RPM (Receiver Power Monitoring) for L1 and L5 bands and is synchronized with an external timing reference to provide precise GNSS time to another device. It supports geofencing, sensor batching, sensor fusion, and sensor navigation and has a GNSS location library API with protocol engines for control-plane (RRLP and RRC) and user-plane (SUPL) interfaces. This GNSS SoC is available in a small footprint and is ideal for Smartphones, Tablets, Mobile accessories, Wearables, and Digital cameras applications.
