1. Introduction
SPK’s SPK-GPS8063 is a low-power, high-performance compact GPS module. It is designed with
the advanced Atheros AR1511 (BF1B-R) GPS IC. The very small form factor and low power
consumption of SPK-GPS8063 makes it especially suitable for a variety of embedded GPS
applications for mobile devices such as personal and automotive navigation, UMPC, etc.. With
its robust design and the extensive support and services backed by SPK ELECTRONICS
CO., LTD., SPK-GPS8063 is the solution of choice for the industry.
