1. Introduction 1.1 Overview GR-213U Smart GPS Receiver is a total solution GPS receiver, designed based on SiRF Star III Architecture. This positioning application meets strict needs such as car navigation, mapping, surveying, security, agriculture and so on. Only clear view of sky and certain power supply are necessary to the unit. It communicates with other electronic utilities via compatible dual-channel through USB interface and saves critical satellite data by built–in backup memory.
