The Leadtek LR9023 module is a high sensitivity, low
power consumption, very compact Surface Mount Device
(SMD). Supporting signal processing of L1 band signals
such as GPS C/A and SBAS (including WAAS, EGNOS, MSAS
and GAGAN), this 22-channel global positioning system
(GPS) receiver is designed for a broad spectrum of OEM
applications and is based on the fast and deep GPS
signal search capabilities of Mediatek MT3329
architecture. Leadtek LR9023 is designed to allow quick
and easy integration into compact size GPS-related
applications, such as:
- PDA, Pocket PC and other computing devices
- Fleet Management / Asset Tracking
- AVL and Location-Based Services
- Hand-held Device for Personal Positioning and
Navigation
