1. Introduction

The Leadtek GPS 9101LP module (LR9101) is a high sensitivity, high gain, low power and very
compact Surface Mount Device (SMD). This 20-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 SiRFStarIII™ low power single chipset architecture. Leadtek
GPS 9101LP is designed to allow quick and easy integration into GPS-related applications,
especially for compact size devices, such as:

PDA, Pocket PC and other computing devices

e

Fleet Management / Asset Tracking
AVL and Location-Based Services
Hand-held Device for Personal Positioning and Navigation
