The Ct-G153 utilized SiRFstarV ™ and features Quad-GNSS for tracking GPS, GLONASS, BDS and Galileo satellites. The product family delivers 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.
Performance
Quad-GNSS : GPS and GLONASS, Galileo and BDS with future firmware update. Improving availability and accuracy of position solutions in urban canyon environments.
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, EGNOS, QZSS, MSAS, GAGAN)
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
SiRFGeoRecovTM Reverse EE makes positioning process being done under power saving mode.
Hardware and Software
Based on the high performance features of SiRFstarV™ low power single core logic.
Adaptive micropower controller
Only 50 to 500μA maintains hot start capability (core logic)
External interrupt input for context change detection
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 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 module was off within 3 days, it could complete positioning process with limited time just like hot start.
