Ct-G551 3.3V Gps Glonass Galileo receiver module GPS SiRF V Module

Product Details

Ct-G551 3.3V utilizes SiRFstarV ™ and features
Quad-GNSS for tracking GPS, GLONASS, BDS and Galileo satellites. The product family deliver highly accurate continuous location, advanced power management and high interference immunity. These continue to push the envelope of performance in sensitivity, TTFF and urban canyon availability and accuracy. With a built-in DSP and extremely low power consumption, the family can get fast location fixes for geo-tagging images or videos, asset tracking and wearable applications.

Premium on-chip software provides a new level of continuous location awareness by employing the following advanced technology :

• Advanced power management allow the GNSS receiver to stay in a hot-start condition nearly continuously while consuming very little power.
• Local or server generated ephemeris prediction, from three days to one month in advance boost sensitivity and performance.

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)
• SMT pads allow fully automatic assembly processes equipment and reflow soldering
• Advanced navigation features
• Smart sensor supported by I²C interface
• External interrupt input for context change detection
  
  

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 or EGNOS,MSAS)
• 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

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.
