SiRFstarII delivers major advancements in GPS performance, accuracy, integration, computing power and flexibility. It is the first GPS architecture designed to be available both as a highly integrated chip set configuration and an IP core. The SiRFstarIIe family consists of the GSP2e highly integrated digital section, GRF2i integrated front end and GSW2e software that provides flexible system architecture for standalone GPS based products. A 50MHz ARM7 CPU has sufficient throughput to support extensive user application software and peripherals. The internal satellite signal-tracking engine provides highly accurate GPS measurements and differential corrections and eliminates the need for a high rate GPS interrupt. This makes SiRFstarII architecture the preferred platform for a wide variety of GPS based consumer products.

It works well where GPS is the main function, "GPScentric" or where the design calls for stand-alone GPS functionality. "GPS-centric applications include handheld GPS, marine GPS, and personal locators. The processing power can be used for such user tasks as running an LCD. The SiRFstarIIe can also be used where a low-cost autonomous GPS is needed such as in vehicle location.
