GPS/AGPS Chipset

Fujitsu’s new chipset for high-sensitivity GPS/AGPS receivers required in communications systems supports telematics and navigation applications for mobile location, tracking and monitoring. The chipset achieves the industry’s highest levels of sensitivity, accuracy and Time-to-First-Fix (TTFF) with low power and a small PCB footprint.

The chipset consists of a baseband chip, the MB87Q2040, which interfaces to a host CPU/MCU via an UART serial interface; and an RF front-end chip, the MB15H156, which supports GPS L-band C/A code. Capable of operating in both “autonomous GPS/standalone” mode and “assisted GPS” mode, the chipset supports leading air interfaces, including UMTS/WCDMA, GSM/GPRS, PDC and CDMA. The chipset is also versatile: a receiver can be initially developed as an autonomous GPS receiver and subsequently upgraded through software to AGPS when assistance becomes available.
