SiRF V gps with glonass module 15x14mm 3.3V

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
- Dimension : 15 x 14 x 2.8mm

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)
