Ct-G340 GPS模組 SiRF V / GPS模塊
產品型號:Ct-G340-S5
產品特色
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
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.
- 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
- 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 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
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 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.
