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. 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 nonmetallic 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.

Step 3: Step 4: Notice: (1) (2)
After the user has connected the NAVI-S to the controlled device, he has to choose the correct COM port number and baud rate for running the map or navigation software. Run the evaluation program. Please refer to chapter 7 How to evaluate the NAVI-S. For safety reason, please do not install NAVI-S while driving. Please set-up the COM port connected with NAVI-S to: Baud rate : 38400 Data bit : 8 Parity : None Stop bit : 1 Flow control : None.

6 How to evaluate the NAVI-S
The SiRFdemo software is available on FALCOMs 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, doubleclick 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 COM3) for SiRFdemo program and set the baud rate to 38400 bps. See figure below
