1. Overview
GR-326 is a high performance, low power consumption and provides you various
application such as car navigation, marine navigation, mapping, surveying, security,
agriculture and so on. The GPS receiver will track up to 20 satellites at a time while
providing fast time-to-first-fix and one second navigation updates. The highly integrated
digital receiver uses the SiRF StarIII chipset.
GR-326 communicates with device (such as PocketPC or notebook) via compatible
dual-channel through RS-232 or TTL and saves satellite data by builtin backup memory.
Low power consumption technology enables GR-326 and your device to save more
operating power. This enables effective and reliable operation in all scenarios. Unique
algorithms and multi-path mitigation provide an accurate fix in the most challenging GPS
environments, such as urban canyons and other areas where GPS signals are weak
or deflected off of surrounding buildings.

The highly integrated GPS receiver uses the SiRF StarIII chipset.
