Qualcomm Logo


SiRFstarV 5e is a Global Navigation Satellite System (GNSS) engine optimised to enable highly accurate location positioning for devices including mobile phones, cameras, and health and fitness products. By supporting fully concurrent GLONASS, GPS, QZSS and SBAS from ROM, the highest accuracy and fastest time-to-first-fix (TTFF) are ensured.

SiRFstarV 5e is offered in a size optimal 0.4mm pitch Wafer Level Chip Scale Package (WLCSP) and a 0.5mm pitch Ball Grid Array (BGA) for low cost PCB applications.

Highly Accurate GNSS operation

Accuracy, Embedded Extended Ephemeris, for faster TTFF, direct to battery, low power.

SiRFstarIV™ GSD4e WLCSP is a complete navigation processor built on a low-power RF CMOS single-die, incorporating the baseband, integrated navigation solution, software, ARM®7 processor, and RF functions that form a complete internal ROM-based standalone or Aided-GPS engine.
