1. Introduction LR9552 Manual V04 The Leadtek GPS 9952 module (LR9552) is a high sensitivity and very compact smart antenna module, with built in GPS receiver circuit. This 20-channel global positioning system (GPS) receiver is designed for a wide range of OEM applications and is based on the fast and deep GPS signal search capabilities of SiRFStarIII™ architecture. Leadtek GPS 9552 is designed to allow quick and easy integration into GPS-related applications such as: λ λ Car and Marine Navigation λ Fleet Management /Asset Tracking λ AVL and Location-Based Services λ Hand-Held Device for Personal Positioning and Navigation PDA, Pocket PC, and other computing devices 1.1. Features Hardware and Software λ Based on the high performance features of the SiRF GSC3f/LP single chip λ Compact module size for easy integration: 25 x 25 x 8.9 mm (with 4 mm patch antenna) 25 x 25 x 6.9 mm (with 2 mm patch antenna) [option] λ Fully automatic assembly: reflow solder assembly ready λ Hardware compatible with SiRF GSW3.2 serial software Performance λ Cold/Warm/Hot Start Time: 42/38/1 sec. λ Reacquisition Time: 0.1 second. λ RF Metal Shield for best performance in noisy environments. Interface λ RS232 or TTL (option) level serial port for GPS communications interface λ λ Baud Rate: 4800 ~ 57600 baud (default 4800). Protocol: NMEA-0183/SiRF Binary (default NMEA). © 2006 Leadtek Research Inc. All rights reserved. Preliminary Confidential - Information is subject to change without prior notice. Page 1/18
