GPS: Not Just a Numbers Game

Author: Allan Travid
Many of us can remember back to the years P.C. (pre-computer), before technology had integrated microprocessors into everything from kitchen toasters to depth sounders. Navigation was pretty much a manual chore, and the ability to confirm your charted position with a glance at a loran display was high-tech stuff. The capabilities we take for granted today, thanks to a successful marriage of computers and pixel-grid LCDs, until recently would have seemed like pure science fiction.

Microprocessor Design Many skippers learned to think in terms of loran time delays (TD). Still today, these capable captains can tell their boat's heading as easily as they can tell time when looking at a clock by watching the loran numbers change. They learned when to switch from one chain of loran towers to another, how to avoid baseline extension problems, and how to prepare for bad weather that knocked out their loran signal (usually just when they needed it most). Though some will debate whether it's for the better, navigational times have changed.

The A+ Core Hardware exam tests your knowledge of the central role played by the system's microprocessor, which has become essential knowledge for the professional PC repairperson. There was a time when replacing the CPU was very complicated. However, today's motherboards feature sockets and slots into which several types and versions of microprocessors can be interchanged. You still have to watch out for compatibility issues, but it's not uncommon for customers to want you to upgrade their PC instead of replace it.

Intel Motherboard People in the business of determining what consumers want have discovered that we prefer to work with pictures rather than numbers. Just as computer operating systems have gone from text-based DOS to picture-oriented Windows, today's world of electronic navigation has shifted from numbers to graphics. Consumer surveys and focus groups also reveal that we want one-button simplicity, or as close to it as possible. Thanks to computer power, GPS receivers take full advantage of a system's ability to do practically everything automatically, making most loran problems history.

Satellite navigation has a receiver that helps you to determine your position exactly with the help of satellite signals from a network of satellites. The system is based on the astounding technology of the Global Positioning System (GPS). Each GPS satellite transmits radio signals that are picked up by the GPS receivers. The receiver then picks up this signal from the GPS satellites that are four in number and calculates its position on land. The information that these signals provide includes position, velocity, weather, and timing.

Gigabyte Mainboard

1. The primary computing unit in a mainframe computer. in the PC today, this is usually a Intel Pentium class processor or competing AMD or Cyrix microprocessor. In separate device with a microprocessor, the microprocessor is the CPU for the device. If a device has a microprocessor, it is said to be a "Smart" device, without a microprocessor, it is a "dumb" device.

History Of Microprocessor GPS 101

GPS Glossary Handy terms to know when you're shopping for a GPS. GPS (Global Positioning System): GPS was designed by the U.S. Department of Defense, but has since made its way into consumer electronics. Widely used by boaters for many years, GPS technology is now available to automobile owners. four GPS satellites orbit the earth and provide incredibly accurate position and time information. GPS makes it possible for you to get directions to almost any destination you program into your navigation system.

Ecs Motherboard GPS receivers display your position in latitude/longitude numbers, along with your speed and direction of travel. If you're navigating to a waypoint (a target destination stored in memory), information such as the compass bearing to your destination, distance to go, time to go and the speed at which you're actually approaching your destination (velocity-made-good) can also be displayed.

They do not know the name, phone number, address, email address, or any personally identifying information about the user.

Mainboard Driver Using these numbers to navigate to a waypoint is not as complicated as it sounds. Simply steer the boat so the compass bearing and actual boat-heading numbers match. When the distance-to-go number on the display has counted down to zero, it's time to start fishing. All the other numbers just give you something to tell the kids when they want to know if you're there yet.

Computer Motherboard If you find it confusing to steer by the compass to keep your bearing and heading numbers aligned, you can use your unit's graphic steering display to make it easier to hold your course. These usually place you on a virtual highway, complete with centerline. As long as you stay on course, the highway appears to stretch out straight ahead of you. If you stray to the right or left, an arrow or other pointing icon shows you which way to steer to get back on course. On some units, the graphic highway angles to the right or left when you're off course. Corrective steering straightens it up on the screen. A course-deviation indicator constantly displays how far your boat is off course to the left or right. A waypoint icon appears ahead of you on the highway and gets closer as you approach your destination.

Asus Mainboard GPS receivers - from $150 handheld units on up - include a track-plotter display that shows a bird's-eye view of your position. An icon representing your boat appears in the middle of the screen, and waypoints appear in their respective positions around it. When you decide to navigate to one of the waypoints, the track plotter draws a course line on the screen from your position to the destination waypoint. The plotter function then draws a second line on the screen marking your track as you travel. The more accurate your steering, the closer the track line stays to the course line.

Microprocessor Programming You can adjust the width of the area shown on GPS screens from a fraction of a mile to hundreds of miles. As a rule of thumb, you set the screen to represent the smallest area that shows both your present position and your destination waypoint. The smaller the area represented on screen, the faster steering errors show up and the quicker you can make course corrections to avoid wasting time and fuel.

Ecs Mainboard GPS With Pictures

Motherboard Manual Electronic chart plotters represent the ultimate in graphic navigation. You use them like track plotters, but with a chart picture overlaid on the screen. You see your boat, your course and your destination all laid out on the electronic chart. Plug-in cartridges provide the digital cartography replicating actual charts of your local area. The position of your boat and waypoints comes from the GPS receiver.

Shuttle Mainboard GPS receivers can be interfaced with other electronics on the bridge as well. Many radars and sounders accept and display navigation data. Interfaced autopilots can steer automatically to and from your present position to a waypoint and from one waypoint to the next. You can even mark waypoints at both ends of a successful trolling run and let the autopilot steer the boat back and forth between them. While tracking your progress on the chart plotter, you can mark the positions of strikes as they occur. Additionally, interface your GPS with your radar and you can see your waypoint encircled on the actual radar screen - taking much of the guesswork out of picking out your destination target on the radar display.

Microprocessor Architecture Electronic navigation isn't just numbers anymore, and even those of us who are a bit less salty can reap its benefits. Still, those who build the systems - and experts who teach others how to use them - stress that they are aids to navigation, not substitutes for common sense. All boaters should acquire the ability to get home using a compass and a chart, just in case. After all, power failures do happen.
