Abstract:	In Japan, 2 million or more car navigation units are sold in each year. In recent years, demand for high functionality, high performance, small size and low cost of car navigation systems has been more and more growing. To meet this market demand, Aisin AW as a navigator manufacturer, Hitachi Ltd. as a IC vendor and Japan Radio Co., Ltd. as a GPS core manufacturer have made a joint development of Car Navigation SOC. To achieve the GPS receiving function, JRC has developed a GPS baseband IP, an RF module and a GPS middleware (software package). The GPS baseband IP incorporates GPS functions in the navigation SOC. This GPS-IP is based on the JRC GPS core (CCA-450) and loaded with a dedicated “high-speed search channel” to realize the fully satisfactory performance of TTFF (hot start: 7 sec. typical and cold start: 43 sec. typical).
