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 NAVIS.
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.

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.
