LR9548X

GPS Module GPS Engine Board GPS模块



LR9548X GPS module is a high sensitivity, low power, Surface Mount Device (SMD). This 20-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 SiRFstarIII GSC3f/LPx chipset, SiRF’s newest chipset technology.

The LR9548X is also pin-to-pin compatible with the LR9805 (LR9548) for easier and faster transition.



The LR9548X is designed to allow quick and easy integration into GPS-related applications such as:

-PDA, Pocket PC, and other computing devices

-Car and Marine Navigation.

-Fleet Management /Asset Tracking.

-AVL and Location-Based Services.

-Hand-Held Device for Personal Positioning and Navigation.
