Overview

GR-82 module is designed on the base of SiRF star II Architecture and is provided as a complete solution for GPS receiver for OEM products.Its positioning functionality and application meet the strict practical requirements and standards on car navigation, mapping, surveying and agriculture.
GR-82 communicates with other electronic utilities via compatible dual-channel through RS-232 or TTL and saves critical satellite data by built–in memory backup. With low power consumption, the GR-82  tracks up to 12 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.
