The HOLUX GR-213 Smart GPS Receiver is a total solution GPS receiver, designed based
on SiRF Star III Architecture. This positioning application meets strict needs

Only clear view of sky and certain power supply are necessary to the unit. It communicates

or TTL and saves critical satellite data by built-in backup memory. With low
power consumption, the GR-213 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
