1. Introduction
1.1 Overview
The DA-80101 series GPS receiver incorporates low noise, high sensitivity, low power consumption
SiRF StarⅢchipset solution in a compact, waterproof enclosure. The receiver is very suitable for
broad applications such as car navigation, mapping, surveying, etc. Only clear view of sky and
certain power supply are necessary to the unit. It communicates with other host device via one full
duplex serial communication RS-232 port or one universal USB port. With its ultra low power
consumption, the receiver tracks up to 20 satellites at a time while offering fast time-to-first-fix,
re-acquires satellite signals less than 1 second (average) and updates position data every second.
