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 signal 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
