1. Introduction
1.1 Overview
The E-705 GPS Receiver integrated antenna is a total solution GPS receiver, designed based on EVERMORE
on-chip hardware tracking loops technique for use in a wide range of application. 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 RS-232. With low power consumption, the E-705 tracks up to 12 satellites at a time, re-acquires
satellite signals in 100 ms and updates position data every second. The fast time-to-first-fix (TTFF) allows the
unit operates with low power consumption.
1.2 Features
The E-705 provides the following features:
1. Fast TTFF and low power consumption.
2. High performance receiver tracks up to 12 satellites.
3. Supports NMEA-0183 protocol.
4. Compact design ideal for applications requiring small space.
5. Optimized for navigation in urban-canyon environments.
6. Automatic cold start with no user initialization required.
7. Water resistance.

2. Operational Characteristics
2.1 Initialization
As soon as the initial self-test is complete, the E-705 begins the process of satellite acquisition and
tracking automatically. Under normal circumstances, it takes approximately 40 seconds to achieve a position fix,
15 seconds if ephemeris data is known. After a position fix has been calculated, information about valid position,
velocity and time is transmitted over the output channel.
The E-705 utilizes initial data, such as last stored position, date, time and satellite orbital data, to achieve
rapid GPS signal acquisition and fast TTFF. If significant inaccuracy exists in the initial data, or the orbital data
is obsolete, it may take more time to achieve a navigation solution or cold–start automatic-locate will be invoked.
However, acquisition performance can be improved significantly of the host initializes the E-705 with a rough
estimate of time and user position.
2.2 Navigation
After the acquisition process is complete, the E-705 sends valid navigation information over output
channels. These data include:
1) Latitude/longitude/altitude
2) Velocity
3) Date/time
4) Error estimates
5) Satellite and receiver status
The E-705 will perform 3D navigation when 4 or more satellites are tracked. When 3 or fewer satellites are
tracked, altitude-hold is enabled using the last computed altitude and 2D navigation mode is entered.
With signal blockage or rising and setting of the satellites, where a change in satellite constellation used for
position fix occurred, large position error may result. The E-705 incorporates a proprietary algorithm to
compensate the effect of satellite constellation change, and maintains an accurate smooth estimate of the
receiver’s position, velocity, and heading.

4. USB Driver
4.1 System Requirements
IBM, Pentium or above and other compatible PC; 16 MB and above memory; Windows 98/Me/2000/XP; VGA
Graphic Adapter.
4.2 Installation
1. Copy entire <E-705 USB> folder from CD to hard disk.
2. Connect E-705 USB connector to computer. While the computer automatically starts the installation
program, please direct the driver to the <E-705 USB> folder.
3. After the installation is complete, go to <Device Manager> and select <Ports (COM & LPT)> to verify if a
virtual COM port <USB to Serial Port> was created.
4.3 Important
Verify the COM port # to start using your own navigating software.
1. Click <Start> menu, select <Settings>, then enter <Control Panel>.
2. After entering <Control Panel>, select <System>.
3. Select <Device Manager>.
4. Find the <Connect Port> and check the Virtual COM Port, which was created by the USB driver. Please
note that the Virtual COM Port number might be different from every computer. Before using navigating
software, please confirm the COM Port numbers created by your computer and provided by your navigation
software. They must be the same Com Port numbers. Otherwise, the navigating software won’t receive the
satellite signal for the un-match COM Port setting.
