NAVSTAR 10/12 series Introduction

Fix Text Below, so that Words Do Not Separated Strangely at End of each Line. For centuries, sailors have been searching for a reliable and precise method of travelli ng the world’s

waterways. From celestial navigating to the modern navigation techniques as Loran, Decc a navigator, Omega or Transit Satnav, each system has had its problems with weather, range and reliability. Without doubt, the “Global Positioning System”, or GPS for short, is the most significant advance i n navigation: it provides the navigator a position 24 hours a day, 365 days a year in any weather condition. GPS is a satellite based navigation system which provides suitabl y equi pped users with accurate position, velocity and time data. Originally the GPS, developed by the U.S. Department of Defense, was conceived for military purposes, but now it is used in a host of civilian applications. GPS navigation uses satellite signals to determine your position in relation to a set of satellites orbit i ng the earth. The GPS constellation of satellites continuously sends radio signals, containing the precis e position for each satellite back to earth. By knowing the position of 3 or 4 satellites and calculating various time differences between transmitted signals, the GPS receiver can determine its present position anywhere on earth, and thanks to continuous updates, calculate speed and course information.

NAVSTAR 10/12 series Introduction

HOW GPS WORKS

Currently, the GPS constellation consists of 26 orbiting satellites (i ncluding 3 spares), but this num ber will increase in the future. The GPS receiver computes an accurate position by calculating the distance to the GPS satellites that orbit the earth. Signals are required from 3 satellites for two dimensional (2D) position calculati on whilst 4 satellites are required for three dimensional (3D) position calcul at i on. As mentioned earlier, GPS satellites are not geostationary, but they are orbiting t he earth as illustrat ed on the following figure:

[The GPS constellation] Note that position is repeatedly fixed through the following three steps while any 3 satellites are in line of sight. The position calculation procedure is indicated in the following three st eps:

1. GPS satellites continuously transmit their own precise orbital data and the GPS receiver computes their locations by receiving this data.

2. In this receiving process, the GPS receiver measures very accurate distances to the satellites, using the "Spread Spectrum Modulation" method. Excellence in GPS's position-fi xing accuracy is mainly due to this technology.

3. When the satellite locations and their distances are known, the GPS receiver fixes its own position by triangulation:

NAVSTAR 10/12 series Introduction

[The GPS position calculation]

As illustrated in the previous figure, the position is calculated as the meeting point of three spheres, which are drawn around the three satellites with diameters d1, d2 and d3.

Position Fixing Accuracy: HDOP The GPS fix accuracy is due to the locations of 3 satellites in the sky. High accuracy is obtainable when the satellites are widely scattered in the sky; on the contrary, accuracy is reduced when the satellites have gathered in a narrow space. In the following figure, in both cases it is possible to obtain the GPS fix, but in the left case the accuracy will be higher than the right:

[HDOP]

The index for position-fixing accuracy is called HDOP ("Horizontal Dilution Of Precision"). The smaller the HDOP value, the more accurately the position can be fixed.

NAVSTAR 10/12 series Introduction

#Sonar - How it works-

The NAVSTAR 10/12CF sonar consists of a transceiver display unit and a dual frequency transducer. An electronic signal pulse is generated in the transmitter section of the displ ay unit. When coupled to the transducer, this signal is converted into an ultrasonic signal and is transmitted toward the bottom. The signal travels through the water until it strikes an object or the bottom. It is reflected back , hits the transducer surface, and is reconverted into an electronic signal by the transducer. Then it is amplified in the receiver section, processed in the main logic section, and displayed, as an image on a LCD screen. (Picture 3) When your boat travels from point A to point B as shown in Picture 1, the beam of the transducer installed on your boat shown a cross-sectional view in the water. Picture 2 indicates a cutaway view under the water when your boat moves from A to point B.

The screen shows the latest scan data at its right position. After the next scan, the previous data is moved to the left and the latest scan data is shown at the right positi on. When your boat moves from point A to point B, the screen shows the scan data as show n i n Pict ur e 3.

Installation of GPS ANTENA

The installation of the GPS ANTENNA.

The GPS ANT must be installed at the highest area of the boat and the easiest place to receive the signal from the satellites. If there are obs tac les around the GPS ANT, it isn't able to receive all s ignals. The receiving time could be longer or the receiving power would be weaker . Please, follow the instruction for your installation.

1. Keep from a metal.

2. Over 4m away from a MF/HF ANT, VHF or HF whip ANT.

3. Over 1.5m higher than MF/HF ANT.

4. Over 1m away from a receiving ANT.

5. Don't put the GPS ANT into the range of radar's beam. (Range: 30°～40°)

6. Over 1m away from the scanner of the radar.

7. Over 5m away from the ANT of the Inmarsat.

8. Over 3m away form the ANT of the roof.

9. Over 2m away from the engine.

10. Over 0.5m away from the metal surface.

※Warning: Not less than 0.5m away from the metal surface. If the environment can't be satisfied from 1 to 10, have NO. 10 satisfied and consider the others.

Installation of the Transducer

A careful installation will assure maximum performance from your new NAVSTAR 10/12 series.

Display Unit Location

Select a location for your Display unit that provides easy viewing from all likely operator’s positions. The display unit is designed to be mounted on either a console or from an overhead surface. The Display unit is also designed for flush mounting using six threaded holes on the rear panel. Locate the display in an area with protection from the elements and avoid direct sunlight on the viewing window. Also, consider access to the rear panel of the unit for connecting power and cables to the various remote sensors. The mounting surface must be flat and solid to support the unit and prevent vibration. There should be access to the inside of the surface to permit through bolt fastening for the mounting bracket.

Display Unit Installation

Temporaril y i nst al l the mounting bracket on the NAVSTAR 10/12 series displ ay unit and pl ace the unit at the selected location.

CAUTION The Display unit is unstable when the mounting bracket is not secured. Hold the unit in place at all times.

Check the suitability of the location and make any adjustments. When all is satisfactory, use the holes in the mounting bracket as a guide and mark the holes locations on the mounting surface.

Installation of the Transducer

Installing the Transducer Cable-

Thru-Hull and tran som-Mount Installation cable, with the connector attached, is supplied with the transducer. During the installation, do not cut the transducer cable or remove the connector. Do not try shorten or splice the cable. The

transducer cable includes several wires, along with shielding and insulation. If the cable is cut, it cannot be repaired. (Cutting the cable will also void the warranty.) During installation, if you need to drill any holes for the cable, they must be large enough to accept the connector .(3/4" or 19mm) This will allow you to complete the installation without cutting the wire.

1st) For a transom-mount installation - Route the cable up and over the top edge of transom. Secure the cable using cable clamps. (These clamps are available from your local marine equipment supplier.) If you do not want to expose the cable on the deck, you may drill a new hole (3/4" or 19mm) through the transom for the cable. (Remember - this hole must be large enough to accept the cable with the connector attached. Do not cut the cable!) To seal the opening, use a feed-thru cap where the cable passes through the transom.

2nd) For either type of installation - Run the cable through the interior of the boat.

3rd) Be careful not to tear the cable jacket when passing it through bulkheads and other parts of

your boat. Secure the cable in place using Nylon Wire Ties. Coil the extra cable and tie it out of the way.

4th) If transducer cable is not long enough, 15 & 30 foot extension cables are available from SI-TEX When you attach the extension cable, be sure that the connections are tight and watertight. Use Dow Corning DC-4 or an equivalent sealing compound to protect the connector assemblies.

- 25 -

Installation of the Transducer

Installing the Power Cable-

) The 6-foot power cable supplied with the dis pl ay unit should reach the source of DC power.

Connect the power leads directly to the main battery isolation switch or breaker, or route the power leads to the DC power distribution panel. At the power source, connect the red wire to the positive terminal (+), and the black wire to the negative terminal (-). The negative terminal may also be called "ground" or "earth." (The display unit is internally protected if you accidentally reverse t he polarit y of the power wires.)

) Attach the red or positive wire to a 5 amp circuit breaker. If the unit is connected directly to the

boat's battery, include a 2amp in-line fuse. (In-line fuses are available at most marine supply stores.)

) To prevent any interference or electrical noise, separate the Sonar power wiring as much as

possible from other devices. See the section on "EMC Install ation Guideli nes."

) If you need to extend the power wiring by more than 10 feet, use a larger wire size. This will

allow the wires to deliver the correct voltage in spite of the longer wire distance. For runs of 20 to 35 feet, use #14 AWG wire. If you need to extend the power wiring, be sure all electrical connections are solid and durable. Insulate all connections using heat-shrink tubing or electric al t ape. You may use crimp connectors or a terminal strip, but be sure to use good-quality marine-grade parts.

) Plug in the power cable at the rear of the display unit.

) When you press the Power button, the display unit should turn on. If the unit will not turn on and

you suspect that you may have reversed the power connections, check the DC power lines all the way back to the battery. If the polarity is not correct, reconnect the leads properly and try again. (The display unit is internally protected if you accidentally reverse t he polarit y of the power wires.)

- 26 -

Installation of the Transducer

Installing a Thru-Hull Transducer Follow these instructions if you are installing the thru-hull transduc er.

) Once you have decided where to install the transducer, drill the hole for the part. B egi n by

drilling a small pilot hole (1/8" or 3mm) from the inside of the hull. (This small hole can be filled easily if the mounting location is not suitable.) Before you drill the hole, be sure you will be able to reach the large nut on the top of the transducer, once it has been mounted. Also be sure there will be enough clearance for the cabl e. If there is a strake or other feature on the hull, drill from the outside of the hull instead.

) Drill a larger hole from the outside of the hull using the appropriate size hole saw or paddle bit

for the selected transducer.

) Uncoil the transducer cable. Remove the large hex nut from the housing and slide it over the end

of the cable.

) Thread the cable through the hole to the inside of the hull. Never pull or carry the transducer in

place by pulling on the transducer cable.

) Apply a thin layer of sealant (1/8"" or 3mm) to the transducer between the upper flat surface of

the transducer and the faring block. Use a high quality marine sealant suitable for underwater use. (Caution do not use 3M 5200) Also apply a thin layer up the side walls. this should cover all of the threads where the part will touch the hull material, plus an additional 1/4""(6mm). This will seal the threads for the large hex nut.

) Push the transducer housing (with the sealant applied) into the hole from the outside of the hull.

Twist the housing slightly to squeeze out any excess sealant and to get a good seal. Be sure that the transducer is aligned so that the correct part of the unit is toward the bow of the vessel. Hold or prop the transducer in place temporarily.

- 27 -

Installation of the Transducer

) Go to the inside of the hull and slide the hex nut over the end of the cable. Fit the hex nut over

the end of the transducer and tighten it. (On a vessel with a wooden hull, do not tighten the nut completely right away. Allow some time for the wood to swell after the vessel is put in the water. Be sure that the correct end of the transducer is pointing forward see Picture 1-1

) Remove any excess sealant from the outside of the unit to assure smooth water flow over the

face of the transducer.

) As soon as the boat is placed in the water, check for leaks. Check again within 3 to 5 hours.

(You may not be able to see a small leak right away.) If there are any leaks, you must repeat the installation procedure.

- 28 -

Installation of the Transducer

Positioning the Transom-Mount Transducer

Follow these instruction if you are installing the transom-mount transducer. Begin by finding the best location for the mounting bracket. Here are the rules: If your boat has one propeller (outboard or inboard-outboard), mount the transducer about 18"(455mm) to the side of the centerline of the boat. See Picture 1-2 Choose the side that is on the down stroke of the propeller.(This is usually the starboard side of the boat.) This will reduce any interference cause by air bubbles. If your boat has twin propellers (outboard or inboard-outboard), place the transducer near t he centerline of the boat. If the propeller can be turned to steer the boat, allow at least 2"(50mm) beyond the swing radius of the propeller. This will prevent the propeller from damaging the transducer when it is turned. Do not mount the transducer behind any hull fittings, intakes, or other parts which extend from the hull. These may cause turbulence or air bubbles.

If the boat will be carried on a trailer, be sure the transducer will not hit any rollers, bunks or fittings on the trailer.

Installation of the Transducer

Mounting the Transom-Mount Transducer

Follow these instructions if you are installing the transom-mount transducer.

). On a boat with a fiberglass hull, the leading edge of the transducer should extend 1/8""(3.2mm) to

1/4""(6mm) below the bottom edge of the hull. See picture 1-3. On an aluminum hull, the transducer should extend a bit more - 1/4"(6mm ) to 3/8"(9mm). If the boat will be operated at high speeds, t he transducer may be mounted closer to the centerline of the hull.

) The lower surface of the transducer should tilt down toward the rear at a slight angle(2° to 5°). The

mounting bracket includes a wedge. Depending on the angle of the transom on your boat, you may need this wedge to get the correct angle for the bottom of the transducer.

) Looking at the rear of the boat, be sure the bracket is vertical (perpendicular to the water line).

) Hold the bracket (and the wedge, if used) against the transom and trace the position of the screw

slots.

) Remove the bracket. The screws in the outer slots should be placed about 1/4"(6mm) up from

the bottom of each slot. The screw in the center slot should be placed 1/4" (6mm) down from the top. (This will allow you to adjust the bracket up or down a bit.) Drill pilot holes 3/4""(19mm) deep. Use a 9/64" (3.5mm) drill bit. To prevent drilling too deeply, wrap masking tape around the drill bit about 7/8" (22mm ) from the tip. Drill in onl y as far as the tape marker. If you are attaching the bracket to a fiberglass hull, you can minimize any surface cracking of the gel coat. Before drilling each pilot hole, drill a shallow hole (chamfer) at each location about 1/16" (1.5mm) deep. Use a 1/4"(6mm) drill bit.

) Attach the bracket to the hull using the pinhead screw with flat washers. Before you tighten the

screws, apply a good-quality marine sealant to the pilot hole. This will protect the hull from water penetration. Do not tighten the screws completely yet.
