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: -161dBmSBAS (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
Advantage
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.
