Ever gotten lost before? If you have, you will know that it is not as fun as it sound. Matter of fact, it is not fun at all. Believe me; I am speaking from a personal experience. By the time my family and I found our way back, we realize that we are miles and miles away from our destination. Solution?

Well, by now you know that the solution lays in a 3 letter word “GPS”. Let me tell you that having a navigation system is what completes driving. Without I you fell limited in where you can go and some times have to rely on others for direction. Lately, the buzz is on the new Garmin nuvi navigation systems and particularly, the Garmin nuvi 850 4.3-Inch Widescreen Portable GPS Navigator with Voice Command and FM Transmitter. Ok, I know that is a mouth full.

But for all you gadget people out there, you’ll know that this baby has a ton of new feature. Like

New – Photo Navigation lets you upload geo-coded photos from a phone, geo-coding camera or photo site and navigate to them.  New – Send addresses directly to your Garmin from Google Maps or MapQuest New – Voice Recognition — Just tell it what you’re looking for Where Am I? — instantly shows you all of the emergency services nearby Where’s My Car? — never forget where you parked again

And my favorite

Garmin Lock — keep others from using your navigator

 I really like this new feature because lately, navigation system are targets for thieves, but for the Garmin nuvi 850 4.3-Inch Widescreen Portable GPS Navigator, you will have the opportunity to create your own 4 digit pin# so that no one else can hack into your navigation system to know your address, etc

Here is a review of a costumer

 “Nuvi.
I recently bought a Nuvi 850. Here’s my advice for what it’s worth.

The real value of a Nav system comes from the fundamentals.
* Receiver
* Maps
* Routing Engine
* Display
* User Interface

Garmin does a solid job in all these areas. But that’s not why you’re paying a premium for an 800 series
This model has a couple of “nice to have” features that were introduced on the 700 series of Nuvi’s.
* Where Am I
* Where’s My Car”

Another costumer said

 “This unit functions perfectly as it is described. The voice-activation is nearly perfect. Probably one of the best implementations to date that I can remember. The map is a bit under-detailed for the price but it gets you where you need to go. Voice commands from the unit are very easy to understand. Controls are easy to navigate as are the menu options.”

 Now I know that not everyone is crazy about the Garmin nuvi 850 4.3-Inch GPS, that is why Garmin nuvi have other navigation system with similar features as the 850 GPS.

together and GPS chipset revenue is expected to more than double to $1.3 billion in just three years time,

according to In-Stat. The GPS-based NextGen system, slated for completion by 2025, will straighten routes (blue)

and allow more planes to safely share the skies. Currently, Air Traffic Control Towers (ATCT) guide planes through

takeoff, then hand them over to a Terminal Radar Approach Control (TRACON) facility that keeps approach and

departure corridors orderly over the next 50 miles. The GPS system has been designed to be as nearly accurate as

possible. However, there are still errors.

Cell phone GPS tracking can also be a useful feature to the emergency services or police when responding to a 911

call from a GPS cell phone. For this reason, the FCC has legislated that wireless networks provide location

information for 911 calls made from cell phones. Cell phone GPS tracking systems is touted as one of the most

advanced technological milestones in the history of mobile communication systems. Global Positioning Systems (GPS)

enables the users to trail his own location through the analysis of satellite signals beamed down from many

satellites. Cell phone GPS website Mandated in the aftermath of September 11th, the Federal Communication

Commission (FCC) required cell service providers to make GPS tracking of cell phone calls possible. All phones made

since 2005 are GPS-trackable.

Cell phone GPS tracking is one of those advances. Cell Phone GPS tracking can prove useful in many walks of life

and especially when any emergency arises. Picture the scene of a road accident where injuries have occurred.

Update: Nokia intend the N95 to be a powerful one for all replacement for a media player, digital camera, digital

camera, PDA and now a GPS navigation device. It features a 2-way slide concept to simplify switching between

different functionalities. Nokia, Motorola and Beneflon are just a few of the companies now providing GPS-enabled

phones. This will change as the other manufacturers catch up, then we will see this technology being installed as a

default inclusion.

A good motorcycle GPS system can turn a disaster into a triumph. It won’t stop it raining, they aren’t that good, but it should ensure that you get to where you want to go with the minimum of problems via the best route.

Modern GPS is an extremely valuable tool to make navigating a snap. In the past it wasn’t totally user friendly for the inexperienced user, giving limited information relating to your position on the planet, and not a lot more. Extremely useful for some, like those in the military, but of limited value for most of us who want a simple efficient and reliable navigation system.

However in the last few years all that has changed and GPS navigation is now a reliable, extremely user friendly and relatively cheap navigation solution for anyone, including bike riders.

Modern satellite GPS navigation systems, for motorcycles, cars, walkers or anyone else who needs one, are extremely good. They are relatively inexpensive considering how useful they are. And now with satellite GPS technology combined with modern mapping software they provide a total navigation solution unlike anything ever seen before.

You can plan your ride before you start it, put the details in your GPS unit and it will plan the entire route for you, and tell you how to get there as you travel, both by screen display and voice prompts direct to your earpiece in your helmet via modern bluetooth technology. Download it all at the end to keep for next time or share with your friends.

With a little time anyone can learn how to use a motorcycle GPS unit and with some practice will be adding a whole new dimension to their rides, particularly the long rides. And you also get all sorts of extras with a modern dedicated motorcycle GPS system that make life a little easier when you’re out on your bike, like the ability to load your favorite music to listen to on the ride, or to display your photos to your friends as you go, or to have up to date real time traffic information so that your GPS can direct you around traffic jams, reselect a new route and save you time, fuel and frustration.

And lots lots more.

In the past riders had to make do with GPS units that were not designed for motorcycle use. They were often intended as hand held or auto GPS systems, and lacked many of the features that are essential to operation on a bike that is used outdoors with the display on the handlebars in the weather, and suffering from all the vibrations that are an integral part of motorcycle use, especially offroad.

But there are now dedicated GPS motorcycle systems that are specifically designed for motorbike riders. They offer the sorts of features that are much more important to bike riders than to other users. These include such things as a display that is easier to read in the sun or rain, waterproofing ability and vibration resistance. None of these are important to, say, a driver of a car, but are extremely important to a motorcycle rider.

The waterproofing of these GPS units for example is tested to exacting standards, and they are designed to be used with a dedicated mount that itself has been designed to minimize vibration problems.

Companies well known in the field GPS design like Garmin or Tom Tom make motorcycle GPS systems that offer all those benefits discussed, and more, and make extremely high quality units that are now in use on many many bikes around the globe.

Systems like the Garmin Zumo or the Tom Tom Rider are both superlative motorcycle GPS systems and if you shop online you can buy these new for well under $1000.

So if you’ve suffered a motorcycle disaster trip, and you’d like to find a way to avoid another one in the future, consider a good motorcycle GPS system. They make motorcycle navigation easy and fun. You’ll never regret it.

NTP (version 4) can maintain time over the public Internet to within 10 milliseconds (1/100th of a second) and can perform even better over LANs with accuracies of 200 microseconds (1/5000th of a second) under ideal conditions.

NTP works within the TCP/IP suite and relies on UDP, a less complex form of NTP exists called Simple Network Time Protocol (SNTP) that does not require the storing of information about previous communications, needed by NTP. It is used in some devices and applications where high accuracy timing is not as important.

Time synchronisation with NTP is relatively simple, it synchronises time with reference to a reliable clock source. This source could be relative (a computer’s internal clock or the time on a wrist-watch) or absolute (A UTC – Universal Coordinated Time – clock source that is accurate as is humanely possible).

Atomic clocks are the most absolute time-keeping devices; however, they are extremely expensive and are generally only to be found in large-scale physics laboratories. However, NTP can synchronise networks to an atomic clock by using either the Global Positioning system (GPS) network, a specialist radio transmission or over the Internet. However, it must be noted that Microsoft strongly recommends that an external based timing should be used rather than Internet based, as these can’t be authenticated.

GPS is an ideal time and frequency source because it can provide highly accurate time anywhere in the world using relatively cheap components. Each GPS satellite transmits in two frequencies L2 for the military use and L1 for use by civilians transmitted at 1575 MHz, Low-cost GPS antennas and receivers are now widely available.

The signal transmitted by the satellite can pass through windows but can be blocked by buildings so the ideal location for a GPS antenna is on a rooftop with a good view of the sky. The more satellites it can receive from the better the signal. However, roof-mounted antennas can be prone to lighting strikes or other voltage surges, so installation of a suppressor inline on the GPS cable is highly recommend.

The cable between the GPS antenna and receiver is also critical. The maximum distance that a cable can run is normally only 20-30 metres but a high quality coax cable combined with a GPS amplifier placed in-line to boost the gain of the antenna can allow in excess of 100 metre cable runs.

A GPS receiver then decodes the GPS signal sent from the antenna to a computer readable protocol which can be utilised by most time servers and operating systems including, Windows, LINUX and UNIX.

The GPS receiver also outputs a precise pulse every second that GPS Network Time Protocol (NTP) servers and computer time servers may utilise to provide ultra-precise timing. The pulse-per-second timing on most receivers is accurate to within 0.001 of a second of UTC.

GPS is ideal in providing NTP time servers or stand-alone computers with a highly accurate external reference for synchronisation. Even with relatively low cost equipment, accuracy of hundred nanoseconds (a nanosecond = a billionth of a second) can be reasonably achieved using GPS as an external reference.

There are certain considerations on portable units in the car. There is nothing worse than the unit falling off its mounting while you are driving. So, is the unit you are eyeing going to be a good fit on your dash? If your system is removable, its a good idea to remove it from the car when parked to avoid excessive heat from the sun or theft. But, if you are like many, you may enjoy its use enough that remembering to carry it with you won’t be an issue. Finding the perfect GPS is not always that easy. Some may be geared for a certain niche or activity and you might find that the different brands might also carry their own strengths. A TomTom GPS might be more effective on the street alone, while a Magellan GPS might have street and trail maps.

Keep in mind that as soon as you have started on your journey, and set the GPS system up to plan your route, you should not touch it again. The GPS should be there to assist you, not to distract you. Ideally, it will give you information about directions through the cars audio system, and you will not need to look at the screen too often when you are driving, as this means that your attention will be diverted away from the road or open water.

Magellan’s in car GPS systems, for example are simple and handy to use when you need to know your exact position without a road map. The first thing to check before you set off on your journey is to make sure that the GPS is loaded with maps of the area you plan to travel in. This can be commonly over looked when purchasing a new unit. There is different software, providing detailed maps for any area, nationally or globally.

You may also want to browse through the available accessories for the GPS you are considering. Major manufacturers like TomTom, Garmin and Magellan GPS will sell their own first party accessories for their units. This can play a minor role in how efficient or effective the unit may be for you and your activity. From windshield mounts to carrying cases and extendable memory. It is a safe practice to leave room for expanding on your GPS unit in the future.

So, if you are on the search for the perfect GPS, it is key to set clear expectations as to what you are looking to get out of a unit. A GPS system is a miracle to some people. Those who simplly want to type in an address and have a personal navigator sitting on their dash, talking them through traffic. Other’s might expect more. Navigating the snowy backcountry and tracking way points to find that perfect peak. If you are one of those die hard outdoorsmen, it may be a safer bet to avoid buying a GPS that does it all, instead of one targeted on your niche activity.

There are three basic choices that consumers have when it comes to marine GPS units and these are as follows: handheld marine GPS units, chart plotting marine GPS units or a computer attached to a GPS. The handhelds are the most affordable, with most of them costing less than $100. Most of these can also be used outside of the boat, which can be used as a navigator for your car or while hiking. These are the smallest of all marine GPS units, but sometimes the small size is a disadvantage when the boat is rocking back and forth and the buttons are tiny and hard to focus on. If you plan on reading it in direct sunlight, make sure you get a version of handheld marine GPS units that are easily readable in such conditions.

Chart plotting marine GPS units are larger than handhelds, so their screens are bigger, wider, and much easier to read. Because of the increased size, these marine GPS units also have bigger buttons that are spaced out more, so people with clumsy hands or large fingers can still use the device without problems. Chart plotting marine GPS units are usually more expensive than the handheld marine GPS units, costing around $400. However, most do come with full color screens, which can help you read important features much better than you would otherwise be able to.

In most circumstances, a computer connected to a GPS is not ideal for boating. Although the screens are larger than both chart plotting and handheld marine GPS units, their screens are not meant to be viewed in direct light, so they usually have to be stored below deck. Plus, they actually cost as much as a regular computer (usually over $1,000). Out of all of the options available in marine GPS units, the best is probably the chart plotting type.
