NAVI-S VERSION 1.04

0 Introduction

0.1 General about NAVI-S

The NAVI-S from FALCOM GmbH is a new GPS receiver that features the

SiRFstarII-low power chipset. This complete 12 channel, WAAS-enabled

provides a vastly superior position accuracy performance in a much smaller

package. The NAVI-S architecture is built on the high-performance

SiRFstarII core, adding an acquisition accelerator, differential GPS

processor, multipath-mitigation hardware and satellite-tracking engine. The

NAVI-S delivers major advancements in GPS performance, accuracy,

integration, computing power and flexibility.

Connecting to the desktop or notebook PC implementing a map or

navigation software, NAVI-S helps you to locate one objects, conduct

personal & vehicle navigation, and/or apply for geographical surveys.

There are two versions as far as NAVI-S receiver is concerned. The

specifications and functions of the receivers are the same.

The difference between both receivers can be recognised by looking on the

bottom side. The first one named NAVI-S-1 with a magnetic base integrated

inside the casing of NAVI-S-1. The receiving side of the NAVI-S-1 is on

the top side. The NAVI-S-1 is designed for in-door on-dash-board

mounting. The NAVI-S-1 is delivered also with an adhesive pad that

enables to stick the unit to non-metallic parts. The second one named

NAVI-S-2 with an adhesive pad on the bottom side of the receiver. The

receiving side of the NAVI-S-2 is on the bottom side. The NAVI-S-2 is

designed for in-vehicle (windows plane) mounting.

For more details about each order option, please see chapter “Order options”

Users are advised to proceed quickly to the chapter "Security" and

read the hints carefully.

1 Security

This chapter contains important information for the safe and reliable use of

the NAVI-S. Please read this chapter carefully before starting to use NAVI-

1.1 General information

The Global Positioning System uses satellite navigation, an entirely new

concept in navigation. GPS has become established in many areas, for

example, in civil aviation or deep-sea shipping. It is making deep inroads in

vehicle manufacturing and before long everyone of us will use it this way or

another.

The GPS system is operated by the government of the United States of

America, which also has sole responsibility for the accuracy and

maintenance of the system. The system is constantly being improved and

may entail modifications effecting the accuracy and performance of the GPS

equipment.

1.2 Restricted use

Certain restrictions on the use of the NAVI-S may have to be observed on

board a plane, in hospitals, public places or government institutions,

laboratories etc. Follow these instructions.

1.3 Children

Do not allow children to play with the NAVI-S. It is not a toy and children

could hurt themselves or others. The NAVI-S consists of many small parts

which can come loose and could be swallowed by small children.

Thoughtless handling can damage the NAVI-S.

1.4 Electrostatic Discharge (ESD)

The NAVI-S contains class 1 devices. The following Electrostatic

Discharge (ESD) precautions are recommended:

- Protective outer garments.

- Handle device in ESD safeguarded work area.

- Transport device in ESD shielded containers.

- Monitor and test all ESD protection equipment.

- Treat the GPS receiver as extremely sensitive to ESD.

1.5 Safety standards

The NAVI-S meets the safety standards for RF receivers and the standards

and recommendations for the protection of public exposure to RF

electromagnetic energy established by government bodies and professional

organisations, such as directives of the European Community, Directorate

General V in matters of radio frequency electromagnetic energy.

4 Installation instruction

4.1 Installation instruction using NAVI-S-1

Choose the best suitable location for mounting the NAVI-S-1. It should be

mounted in a horizontal or near-horizontal position. There should be a clear

horizon-round view from the mounting position, i.e. the NAVI-S-1 should

not be mounted beside objects which block part of the view. The NAVI-S-1

is designed for mounting on a sheet-metal structure. The bottom side of the

NAVI-S-1 has a magnetic base, which should be attached only to a metal

sheet.

Hints

The receiving side of the antenna head is on the top of NAVI-S-1. ♦

♦

The device has to be installed inside the vehicle.

NAVI-S-1 is not water resistant. Do not contact it with water.

The adhesive pad included in the delivery packing is to be stuck on

the bottom side of NAVI-S-1 in case of installing on the non-

metallic parts.

4.2 Installation instruction using NAVI-S-2

a) Use the enclosed cleaning cloth, clean the side of the part, where

the receiver is supposed to be installed.

b) Do not forget, the receiving side of the antenna head is on the

bottom of NAVI-S-2

c) There is an adhesive pad at the bottom side of the receiver.

Remove the protecting sheet (yellow sticker) from the adhesive

pad.

d) Place the adhesive pad onto cleaned area and press the other side of

the NAVI-S-2 to avoid air bubbles.

Hints

The receiving side of the antenna is on the bottom side of the

NAVI-S-2.

Proper functionality requires on-glass-mounting

Does not install the device on metallic or coated windows

To be installed in-door on the immovable parts.

NAVI-S-2 is not water resistant. Do not contact it with water.

6 How to evaluate the NAVI-S

The SiRFdemo software is available on FALCOM’s Website for free

download:

 www.falcom.de/service/downloads/manual/SiRF/ SiRFdemo3.36.exe

1. Run the SiRFdemo software by double clicking the SiRFdemo3.36.exe file.

The SiRFdemo program will be automatically installed onto your

computer.

2. To start the SiRFdemo software, either double-click on the

SiRFdemo3.36.exe file or, if you created a shortcut on your desktop, double-

click the SiRFdemo3.36.exe.

3. The SiRFdemo software will be displayed as follow:

 Before running the software, make sure that, the NAVI-S is

connected to the PC correctly and place it so that the receiver can

have clear view to sky.

 On the activated Data Source Setup window, select the COM (e.g

7 Troubleshooting

Problem Reason Solution

No connection to

the NAVI-S Connection fail

Check if the NAVI-S is connected to a

+5 V DC power supply properly.

Check the other pins, and make sure

they are connected properly.

Test fail Poor connection

Check the connector to make sure it is

well connected. If you still get the

testing fail message, contact your local

vendor.

Open com port fail

All the serial COM port

have been used for other

application program

Close all the other application

programs and rerun the SiRFdemo3.36.exe

program.

There is nothing

shown on the

tracking diagram.

1) NAVI-S can not

receive the GPS signal

in the testing area.

2) The settings are not

correct.

1) Maybe the NAVI-S has not a

enough sight to the sky. Change

the place of NAVI-S to somewhere

with a good view.

2) The settings are as below:

38400 bps,

8 bit data,

1 stop bit

no parity.

No position

Output but timer is

counting.

1) Weak or no GPS

signal at all can be

received.

2) Maybe the GPS

signals are blocked by

buildings.

Place the NAVI-S outdoor away from

obstacles (for instance, high buildings)

The NAVI-S is

running for longer

than 5 minutes

without receiving

valid positions

Maybe NAVI-S receives

not enough data for sure

tracking.

Utilize the program SiRFdemo3.36.exe to

reset the NAVI-S. Please download

the SiRFdemo.pdf from FALCOM’s

Website and read SiRFdemo user

guide.
