LR9548SX SiRF Star III GPS模块

LR9548SX 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 SiRFstar III GSC3f/LPx chipset, SiRF’s newest chipset technology.
The LR9548SX is also pin-to-pin compatible with the LR9805 (LR9548) for easier and faster transition.

The LR9548SX 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.
