LR9553D Specifications Sheet Rev. 0.2

Introduction

The Leadtek LR9553D, based on cutting edge SiRFStar III technology, is a high

performance, low power, 20-channel GPS data logger and receiver with wireless capability.

As such it is a highly compatible Bluetooth solution with extraordinary configurability and

sensitivity. Its battery life-of most concern to customers- has also been greatly improved

thanks to the SiRFStar III LP (Low Power) chipset’ s outstanding power saving capability

in providing fast time-to-first-fix. Not to forget its appealing ergonomics—slim, compact and

lightweight. The innovative switch-mode design not only makes for easy activation but also

enables more power saving when LR9553D is used as a pure data logger which records

your tracking data from the received GPS signals. It provides users enough space to store

their tracking data including the altitude, GPS position, date and time- up to 240 hrs in the

continuous mode. It is not necessary to export the data until the memory is full. LR9553D

also comes equipped with mini USB interface both for easy charging and for users to be

able to export their recorded points to Google earth and Google Maps without a hitch.
