1. Introduction
Leadtek GPS 9531 is a complete GPS smart antenna receiver, including an embedded
antenna and GPS receiver circuits, designed for a broad spectrum of OEM system applications. The
product is based on the proven technology found in other Leadtek 12 channel GPS receivers and
SIRF chipset solution. The GPS smart antenna will track up to 12 satellites at a time while
providing fast time-to-first-fix, one second navigation updates and low power consumption. Its far
reaching capability meets the sensitivity requirements of car navigation as well as other
location-based applications.
Leadtek GPS 9531 smart antenna is designed to withstand rugged operating conditions and
is completely water resistant. With a clear view of the GPS satellites and a PDA or notebook PC to
provide power source and digital map function, a truly portable navigation system becomes a reality
using the Leadtek GPS 9531 smart antenna. The PDA or notebook PC communicates with the smart
antenna via RS-232 serial communication interface. Internal memory backup allows the device to
retain critical data such as satellite orbital parameters, last position, date and time. End user
interfaces such as displays can be added by the application designer.
The smart antenna design utilizes the latest technology and high level circuit integration to
achieve superior performance while minimizing space and power requirements. This hardware
capability combined with software intelligence makes the smart antenna easy to be integrated and
used in all kinds of navigation applications.
