LR9153 SiRF Star 5 GPS Engine Board GPS PCB Module

The LR9153 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.


• GPS, GLONASS, Galileo and SBAS reception for high GNSS availability and accuracy
• High sensitivity navigation engine (PVT) tracks as low as GPS:-165dBm,GLONASS:- 161dBm
• 52 track verification channels
• 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
