Integrated Multi-Constellation GNSS Receiver

Currently Viewing:

Broadcom's fourth-generation multi-constellation Global Navigation Satellite System (GNSS) solution, fabricated in low power 40nm CMOS technology, and adding support for BeiDou (BDS) constellation.

The BCM47531 builds on the success of the ubiquitous BCM4752 GNSS receiver by providing simultaneous multi-constellation support for the GPS, BDS, GLONASS, QZSS and SBAS constellations. The BCM47531 receiver offers fast time-to-fix in all scenarios, accurate real-time navigation, fast re-acquisition of signals after blockage or tunnel exits and best-in-class sensitivity. This receiver chip continues the ability to have low power consumption even with the addition of acquiring and tracking the BeiDou satellites. An additional capability is always-on low-power geofencing support. The BCM47531 is optimized for standalone GNSS solution for smartphones, tablet computers, Internet-of-things devices and portable navigation devices (PNDs).


  • Multi-constellation capability collects data from five satellite constellations (GPS, BDS, GLONASS, QZSS and SBAS) simultaneously and uses the best received signals, resulting in faster signal searches and more accurate real-time navigation
  • Integration of key components such as LNA enables lowest bill of materials cost
  • Low-power operation, allowing location-aware applications to remain active for longer periods of time
  • Applications such as Geofencing™ that provide alerts or services based on location can be completely off-loaded from the smartphone host for ultra-low power operation
  • Urban driving navigation support by applying handset inertial sensor readings into the position computation
  • Best-in-class assisted GNSS (AGNSS) with GPS, BDS and GLONASS assistance data available worldwide from Broadcom's world-wide reference network
