Introduction
The LR9131R GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that fully utilized SiRFstarIV upgrade features. This 48-channel global positioning system (GPS) receiver is designed for a wide range of OEM applications and is based on the GPS ** search capabilities of the SiRFstarIV GSD4e ROM chipset, SiRF’s newest chipset technology. The LR9131R provides flexible bus interfaces (Optional: UART , I2C or SPI reserved for customizing special user applications).

The LR9131R is designed to allow quick and easy integration into GPS-related applications such as: 

?Mobile gaming ?
?Cellular handsets ?
?Cameras ?
?Asset tracking ?
?Other location-aware consumer devices Premium on-chip software provides a new level of continuous location awareness by employing. 
?Opportunistic ephemeris decode and advanced power management, which enable the GPS receiver to stay in a hot-start condition nearly continuously while consuming very little power 
?Full support for client-based and server-based SiRFInstantFix? Dynamic contextual awareness, temperature monitoring, and MEMS sensors that work in concert to conserve power and boost performance ?
?Use of software control modules to achieve power saving state

Advantages 

?Built-in LNA.
?Built-in internal ROM and based on Firmware 4.1.X
?It can remove in-band jammer up to 80db-Hz and track up to 8CW jammers, so the module can prevent GPS ** interference when design-in the electrical device with noisy electrical ** interferences such as Laptop, mobile phone, DSC, etc. ?
?Maintain tracking sensitivity as low as -163dBm, even without network assistance. 
?(SiRF StarIII has only -159dBm sensitivity) ?
?Support SiRFaware technology : ?
?Support adaptive “Micro Power Controller” power management mode. ?
?Only 8mW Trickle Power, 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 needs
