Leadtek LR9151 GPS module SiRFStarV

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.

• 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

• 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

• 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.
