How gps receivers work

Understand how does GPS navigation systems work

A small computer program in the receiver of information translated on the subsequent positions of points on the screen.

This way you can see where you come from and where you actually are, and the track you followed to reach your current position. As you move, the system can also calculate the direction you are moving, by comparing the following positions. If you plan your direction for a longer distance, the receiver can detect signals from several GPS satellites simultaneously.

Bluetooth GPS receivers have the great advantage that they associate with the wireless handheld. The downside is that you have two independent units, each with its own battery that needs recharging. Setting up a BT connection is often more difficult than a wired connection. GPS navigation is the process of moving from one place to another and know where you are compared to the desired navigation uses satellites course.

GPS orbit to determine your position. These satellites continuously transmit radio signals containing the exact position and time of return to Earth. GPS navigation on your position and provides a constant speed and track information. GPS takes navigation to the next level by giving the exact position and course information. Around the world. Whatever the weather or your proximity to the earth
GPS is a satellite navigation system consists of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather, anywhere in the world. No subscription fees or use the satellite signal decreases as GPS.The passes through the atmosphere. The GPS system uses an integrated model that calculates an average delay to partially correct this error, handheld GPS can also be used as a car is also very convenient gps.Utility
Conclusion of GPS navigation, GPS navigation complete consists of chip, processer, antenna, display, speaker, connect and expandable map browser. More GPS satellite navigation receiver, the strong signal to go and navigation is developed.
The accuracy and coverage of GPS navigation can help make your boat safer, smarter and more effective when you can travel.

Pioneer Video Bypass

Since the high demand for the Pioneer parking brake bypass; I have decided to come up with a easy diagram for you to follow which will allow you to play videos while you are in motion.

1. Connect the blue system turn on (Remote) wire to spade #85 (If you have or installing and amplifier connect your amplifier turn on (Remote) wire to this prong also)

2. Connect a grounding wire to spade # 87 which jumps and connects to spade # 86. Then connect the wire to a good ground.

3. Connect the parking brake wire from the head unit (Green Wire) to spade # 30

4. Finish installing your stereo and enjoy your video.

Flared Ports vs. Slot Ports

Many people question what the difference is between flared ports and slot ports. There are fairly basic differences between the two, and depending on your situation, one might suit you better than the other. The common purpose of the two ports is that they must be the correct length for the particular subwoofer box to achieve the desired sub box tuning. There are a few differences that may help in your decision between flared and slot ports for your custom subwoofer box.

Flared ports are very good at virtually eliminating port noise. Port noise is the noise created by the friction of air moving through the port. If you have sharp edges on a port (as with standard round ports, which we do not use), you are going to have significantly more port noise than with a flared port. A flared port requires the smallest acceptable port area for a subwoofer box. Since the ends are flared, and the inside of the port is round (no sharp edges), it is unlikely you will be able to notice any port noise from the subwoofer enclosure. However, if you are running a large, high-powered subwoofer, you will want to use two flared ports. A single flared port is still capable of creating port noise when very large amounts of air pass through it.

With a slot port, you can use as much port area as needed for your application, which is especially helpful in SPL applications. A slot port requires more port area than a flared port to minimize port noise. We generally use a rule of 12 square inches of port area per cubic foot of internal volume of the custom sub box. You may go with a larger port area, but this will increase the total volume and length of the port. In turn, a large port area will mean an increase in the total size of your subwoofer box. Slot ports are the standard for our ported custom subwoofer boxes.

If you are not limited on space, we would recommend going with a slot port for your subwoofer box. If space is tight, and you have a few extra bucks, you'll probably want to use a flared port (or two, depending on your subwoofer size and power). It is possible to achieve the same result from both subwoofer boxes, so the decision between flared ports or slot ports depends on your specific needs for your custom subwoofer box.

Installing a subwoofer in a pre-fabricated enclosure

This guide will cover the installation of one or more subwoofers in a pre-fabricated enclosure. It will also cover the process of hooking up an amp to power the sub.

The easiest way to add low-end punch to your car’s stereo is to install a subwoofer. This guide will cover the installation of one or more subwoofers in a pre-fabricated enclosure. It will also cover the process of hooking up an amp to power the sub.

The first thing to do is to put the woofer into the box. This should be easy as long as you got the right size enclosure. Before actually screwing down the speaker, be sure to connect the included leads to the terminal in the back of the box. Next, screw the woofer down tight into the front of the box and mount the protective grille directly over the speaker.

Put the box in the trunk. For the best sound, the woofer should be facing the back of the car. To keep it from sliding around, consider using high-strength Velcro strips to secure it to the trunk floor. If this is not possible, L-brackets may be mounted to the cargo floor, but be sure not to put any screws through the side of the box. However you decide to secure it, make sure that it is out of the way of anything you put in the trunk.
Now it is time to install the amplifier. Begin by mounting the unit in the desired location. This should be a flat area with a lot of open space so that the amplifier can cool properly. Do not mount the amplifier on the subwoofer enclosure, as the vibrations from the speaker can damage the internal parts.

The next step is to hook the amp up to power. Before doing this, disconnect the negative terminal from the battery. Hook the long positive power cable for the amp to the positive terminal of the battery. If the cable does not have a fuse, you should install one inline within three feet of the battery connection. Consult the amplifier owner’s manual for the size of the fuse. Run the fused positive cable through the firewall and back into the cabin. Remove any trim panels necessary and pull back the carpet so you can run the cable underneath. Once the cable can reach the amp, trim off any excess, strip the end, and connect it to the positive power terminal of the amplifier. For the negative cable, connect it first to the amplifier, then run it beneath the cargo floor of the trunk and connect it to a ground point on the chassis or floor pan.
Next, you need to connect the amplifier to the head unit. You should do this using the subwoofer pre-amp hookup on your stereo. This can be either a stereo (paired RCA plugs) or mono (single RCA plug) connection. Unless you have a mono subwoofer amp, you will need to use a paired RCA cable to plug into the amp. If your head unit has a mono RCA out, this means you will need to use an RCA mono-to-stereo adapter to plug the stereo cable into the mono jack. Run the RCA cable underneath the carpet on the opposite side of the car from the power lines to avoid interference. When you get the cables back to the amplifier, plug them in at the RCA in terminals. Before putting the carpet and trim back, run a small 16-18 gauge wire from the head unit amp remote connection to the remote control terminal on the amplifier. At this point you can replace the carpet and trim panels to make the installation look clean.

The last step is to plug the subwoofer into the amplifier. To do this, use 12-14 gauge speaker wire. If you have a bridgeable stereo amp, you should bridge the amp by plugging the positive wire into the positive terminal for the left output and the negative wire into the negative terminal of the right output. The actual configuration of the bridge will vary from amp to amp, so read the owners manual for specific instructions. If you have a mono amp, simply connect the positive and negative wires. Finally, plug the wires into the back of the sub. If you have more than one sub, you can run a length of stereo from one sub terminal to the other.
Finally, put the negative terminal back on the battery and fire up your system. You will need to adjust the gain and filters on your amp, if it has them. First, turn on the low pass filter (LPF) option. Then, turn the gain all the way down. Turn up your stereo until the speakers begin to distort, then turn it down just a hair until it no longer distorts. With the stereo playing at this volume, turn up the gain on the amp just until the subwoofer begins to distort. At this point, turn the gain down a bit. That’s it; you’re done, and good luck with your new subwoofer.
