The Ct-G**3 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 : ***5 dBm
GLONASS : ***1 dBm
*2 track verification channels
SBAS (WAAS, EGNOS, QZSS, MSAS, GAGAN)
Active Jammer Remover, removes in-band jammers up to *0 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 *0+ 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 *0 to **0μA 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 *0db-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 *@********************
