Key Features
Benefits

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.

SiRFstar V 5e offers a range of features intended to increase accuracy, improve time to first fix and preserve battery power to support a better user experience. These include:

  • Instant Fix Extended Ephemeris (EE) - Devices without wireless connectivity, such as cameras, are able to overcome slow TTFF, a common annoyance for the end user. 5e is capable of autonomously forward predicting EE for three days locally, and for connected devices the solution supports server based EE for up to 31 day for GPS and up to 14 day GLONASS EE.
  • Direct to battery capability - The GNSS chip can connect directly to a Lithium battery supply, allowing for system cost reduction and increased power efficiency. This is implemented by an integrated switched PMU, reducing system level power and eBOM costs.
  • Design flexibility for optimal solution cost – With clear attention to solution implementation, 5e is designed for small size and low power. For example, UART and SPI Flash drive levels are drivable from 1.8v to 3.3v, eliminating the need for level shifters and increasing implementation flexibility
  • Intelligent design – The 5e is designed to be optimized for low power battery operated devices. For instance, in asset tracking applications, the 5e engine can intelligently decide how long to try to acquire satellite signal based around its environment, saving a significant amount of battery power
