As the Intelligent Transportation Systems (ITS) industry grows in both commercial and industrial applications, so does the need for power efficient components used in providing position and timing information. The Global Positioning System (GPS) is fast becoming the technology of choice as significant performance improvements have been demonstrated in recent years (1. Turetzky et al, 1997, 3. Gehue et al. 1998). GPS related ITS applications can perform adequately in even the toughest of conditions such as dense foliage and urban canyons. The next identified hurdle in many ITS systems is a higher level of integration and power efficient operation. A low power version of the SiRFstarI (SiRFstarI/LX) chipset has been developed by SiRF Technology Inc. of Santa Clara, California to address the expectations of future ITS integrated systems.
