  GPS模塊 SIRF V GPS Module


The Ct-G340 w/Ct-G530P module is high performance, low power GNSS receiver, based on the SiRFStarVTM single chipset technology while providing fast time-to -first-fix.

Its far reaching capability meets the sensitivity requirements of car navigation as well as other location-based applications.

Ct-G340 w/Ct-G530P is designed to allow quick and easy integration into GPS-related applications, especially for compact size devices, such as:

  • Fleet Management / Asset Tracking
  • AVL and Location-Based Services



  • GPS, GLONASS, Galileo, BDS and SBAS reception for high GNSS availability and accuracy
  • 52 track verification channels
  • Active Jammer Remover, removes in-band jammers up to 80 dB-Hz
  • Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted), need operator support.
  • SiRFGeoRecovTM Reverse EE makes positioning process being done under power saving mode.
  • RF Metal Shield for best performance in noisy environments
  • High sensitivity navigation engine (PVT) tracks as low as
    - GPS: -165dB,
    - GLONASS: -161dBm
  • Tracks up to 8 CW jammers
  • Enbedded CGEE/SGEE (With back-end server support) speed up TTFF a lot and makes cold start time to be around 20+ seconds.
  • Reacquisition Time: 0.1 second
  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
  • MCX vs. RMCX or RSMA RF Connector select
  • 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 module 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 application
  • Embed CGEE (Client Generated Extended Ephemeris) that can capture ephemeris data from satellites locally and predicts ephemeris up to 3 days. So if the module was off within 3 days, it could complete positioning process with limited time just like hot start.
