產品介紹

The DS-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.

DS-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

Performance
• 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.
• SiRFGeoRecov 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
• SBAS (WAAS, EGNOS, QZSS, MSAS, GAGAN)
• 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 500uA 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

Interface
• DIP type pitch 2.0mm- 2x10 pin header.
• Right angle MCX (RMCX) / MCX / Right angle SMA (RSMA) RF Connector.
• Dimensions : 40.64 x 71.12 x 1.4 mm

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 trace 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 SiRFFawareTM technology
   • Support adaptive "Micro Power Controller" power management mode.
   • < 10mW TricklePowerTM, so user can leave power on all day instead of power off.
   • Idel 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.
