Ensigma Location

Series 4 GNSS RPU | GPS, GLONASS, BeiDou and Galileo

Global Navigation and location IP designed for power constrained devices

The Ensigma Location GNSS IP core supports GPS, GLONASS, Galileo, and BeiDou as well as several Satellite-Based Augmentation Systems (SBAS) including WAAS and EGNOS. The Ensigma GNSS incorporates an ultra-low power CPU core and dedicated hardware blocks which enable lower power consumption. GNSS IP not only supports continuous fix techniques, but it also supports power-efficient ‘capture and process’ for devices that only require periodic location updates.

Features
  • Flexible Multi –Constellation Support
  • Low Power Consumption
  • High Sensitivity
  • LTE Integration
  • Low Cost
  • Robustness/Integrity
General features
  • Support for standard constellation features.
  • Push to fix operation
  • Intermittent positioning on command (external/internal)
  • Supports Assisted GNSS
    • Improves sensitivity / TTFF
    • Position, time, frequency
    • Constellation data (Ephemeris/Iono/UTC data)
    • LTE TCXO sharing for reduced eBOM cost
    • LTE memory sharing for reduced silicon area cost.
  • RF capture and process
  • RF is on for minimum time with samples post processed for optimised power consumption
  • Processing Scales with Clock Rate
  • Captured RF samples can be stored in memory
  • Timing system allows LTE time and frequency references to be shared with GNSS system
Benefits
  • Complete Baseband IP solution
  • End to End Solution with partner Tuner/RF
  • Easy integration into an SoC
Low Power Consumption
  • Minimised RF power consumption during one shot fixing mode by allowing capture of the RF signal to RAM (along with background processing capability with the RF off).
  • Minimised RF consumption and processing requirement in the baseband with duty cycling of tracking operations.
Interfaces
  • Digital I/Q Interface to Tuner
  • Tuner control by host or GNSS Subsystem
  • Interface to Host Processor
  • Serial port receives commands from host and carries tracking data to host
  • 32-bit AXI slave port optionally provides host access to internal shared memory
  • Interface to External Memory
  • 32-bit AXI master port gives the GNSS system access to external memory
Applications
  • IoT sensors and edge devices
  • Wearables
  • Consumer mobile products
  • Asset tracking devices
High Sensitivity
  • Maximising use of memory and processing to recover maximum sensitivity.
