Holux Mouse Type GPS Receiver (GR-213u)

Add to Cart:

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. With low power consumption, the GR-213U tracks up to 20 satellites at a time, re-acquires satellite signals in 100 ms and updates position data every second.
Trickle-Power allows the unit operates a fraction of the time and Push-to-Fix permits user to have a quick position fix even though the receiver usually stays off.

Features

• SiRFstarIII chipset with embedded ARM7TDMI CPU available for customized applications in firmware
• High performance receiver tracks up to 20 satellites while providing first fast fix and low powe consumption.
