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.
