LR9550

  • Add to Compare

Performance

  • GPS, GLONASS, Galileo, BDS and SBAS reception for high GNSS availability and accuracy
  • High sensitivity navigation engine (PVT) tracks as low as
    • GPS : -165 dBm
    • GLONASS : -161 dBm
  • 52 track verification channels
  • SBAS (WAAS, EGNOS, QZSS, MSAS, GAGAN)
  • Active Jammer Remover, removes in-band jammers up to 80 dB-Hz
  • Tracks up to 8 CW jammers
  • Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted), need operator support.
  • Embedded CGEE / SGEE (With back-end server support) speed up TTFF a lot and makes cold start time to be around 20+ seconds.
  • SiRFGeoRecovTM Reverse EE makes positioning process being done under power saving mode.
  • Reacquisition Time : 0.1 second
  • RF Metal Shield for best performance in noisy environments

 

Hardware and Software

  • Based on the high performance features of the SiRFstarV™ low power single core logic.
  • Adaptive micropower controller
  • Only 50 to 500μA maintains hot start capability (core logic)
  • < 10mW required for TricklePower™ mode
  • RoHS compliant (lead-free)
  • Advanced navigation features
  • Smart sensor supported by I²C interface
  • External interrupt input for context change detection

 

Advantages

  • Built-in LNA.
  • Built-in internal ROM and based on Firmware 5.5.X
  • It can remove in-band jammer up to 80db-Hz and track up to 8CW jammers, so the GPS-Mouse can prevent GPS signal interference when design-in the electrical device with noisy electrical signal interferences such as laptop, mobile phone, DSC, etc.
  • Maintain tracking sensitivity as low as GPS @ -165dBm, GLONASS @ -161dBm, even without network assistance. (SiRFstar III has only -159dBm sensitivity)
  • Support SiRFaware™ technology
  • Support adaptive“Micro Power Controller”power management mode.
  • < 10mW TricklePower™, so user can leave power on all day instead of power off.
  • Suitable for battery drive devices that need lower power consumption application
  • Ideal for high volume mass production(Taping reel package)
  • Cost saving through elimination of RF and board to board digital connectors
  • Flexible and cost effective hardware design for different applications
  • Embed CGEE (Client Generated Extended Ephemeris) that can capture ephemeris data from satellites locally and predicts ephemeris up to 3 days. So if the GPS-Mouse was off within 3 days, it could complete positioning process with limited time just like hot start.
