The Global Positioning System (GPS) is a US military system for worldwide navigation. The system consists of 24 orbiting satellites, each satellite has a highly accurate atomic clock on-board synchronised to UTC time. The satellites continuously broadcast time and position information. The time and position information can be obtained worldwide with a GPS receiver and antenna. GPS works continuously in any whether conditions, anywhere in the world. Additionally, there is no set up fee or subscription charges to utilise the GPS systems. Many computer timing systems and NTP Server systems utilise GPS as an accurate external timing reference. GPS timing is generally much more accurate than radio based timing references.

There are many commercially available radio and GPS clock timing references for PC’s. Radio and GPS clocks obtain accurate time from national radio timing references or from the GPS system. The devices have serial or USB interfaces and provide an accurate timing reference to PC’s. Driver software periodically synchronises the system time of the host computer to the received reference time. Often reference clock drivers are available that interface to the NTP application software to provide your own dedicated NTP server.

Radio example receivers often have the asset of having the quality to kite a vantage signal, indoors, end to the hostess computer. However, the start can only be conventional locally to the transmitter. There are a numerousness of raise example broadcasts available: MSF heritable from Rugby, UK; DCF-77 sent from Frankfurt, Germany; WWVB inheritable from Colorado, USA; CHU, Canada and TDF, France. GPS has the favor of providing a round case and ratio solution; however, an externally settled sender is obligatory which can be impractical.

First, you need to undertake various Garmin GPS comparisons. There are many versions available, for many types of vehicles and requirements. When comparing Garmin GPS navigation systems, it’s best to go with what is best for you, not what someone else has or what might seem the best simply because it is the most expensive. For example, you may have been recommended a Garmin

GPS handheld unit by a friend who does a lot of bushwalking, but as a boating person, a handheld unit would not be as useful to you. Similarly, a Garmin portable GPS system is great for someone who is in and out of a car, as they need to take it with them to prevent theft. However a fixed Garmin global positioning system would be better for someone who has no need to be removing it from its mounting all the time (or someone, like a courier, who is in and out of their vehicle more times than they care to think about!). You definitely don’t want your Garmin GPS system to be a hindrance!

Compare Garmin global positioning system prices, and see if it might be cheaper to purchase a Garmin GPS system online. Many places sell Garmin global positioning systems online, so be sure to have a look around as it may be cheaper (even taking into account postage) to buy your Garmin GPS system from an outlet that does not have the overheads a physical shop-front might have. The issue with shopping online is, of course, not being able to ‘play’ with your new Garmin global positioning system. But a trip to the local GPS shop may fix that.

One of the Garmin GPS systems available is the Garmin 2720 GPS. This particular Garmin GPS system offers many features, including the ability to program points of interest (such as speed cameras and school zones) so you need never be caught out again. The flashy Garmin 360 GPS doubles as a personal assistant, boasting facilities such as MP3 players, a translator, and Bluetooth capabilities enabling you to make hands-free calls.

Another good pick is the Garmin c530 GPS - ready to go straight from the box, this unit is a good pick for those needing an ATM or petrol station quickly - just touch and go! Read some Garmin global positioning systems reviews, which are usually unbiased and give both pros and cons for each model.

The basic features you need to look out before you buy a GPS such as:

Map Capabilities
Most GPS models come with internal map capabilities. Manufacturer provides maps with details up to street level in the hard drive. The menu option enables you to access the desired data. Comprehensive street level maps can help you identify the coordinates of the destination on the map by using just the name, or locate the destination on map by giving the coordinates. For some models
you will have to subscribe to a plan to update the maps on an annual basis.
Some models provide map information in memory cards having detailed information of a particular region. Thus you will need extra cards if you have to store information for more coverage. Map cartridges are more flexible but can prove to be expensive.
Some brands provide map information in CD-ROM, DVD-ROM discs.

Receiver type
There are 24 GPS satellites in six orbits around the earth. GPS receivers track these satellites to compute the information of your location, the bearing, distance and time left to reach destination and other route options. Since there are 12 satellites at a time in view, each of them is tracked continuously to generate the information. Latest GPS receivers marketed today are commonly 12 parallel channel receivers.

The associated advantages of tracking more satellites are:
faster cold start
regular initialization
better reception
do not require an external antenna if you are in an open vehicle

Other receiver types are:
20 parallel channel receivers
16 parallel channel receivers
14 parallel channel receivers

Display size
Large displays are a visual treat when you consider buying TVs but not the same when it comes to buying a GPS. The map on the display gives you information regarding:

current location
where next turn is
name of street you are turning onto
estimated time of arrival

While driving, casting your glance away a second longer can prove to be risky, hence a device with a smaller screen will be advantageous. The display should be easy to read irrespective of surroundings. The navigation aids come in various sizes. Some units with screen size as big as 7in. enable you to get connected to external video devices. Some hand held ones are as small as 1.5in.X 0.9in.) Some of the convenient, easy to read GPS are:

3.5 in.
2.in. x 2.1 in.

Resolution
Screen resolution decides how clearly you can see and read in broad daylight. Color, glare free LCDs are soothing to the eyes. High end models have color screens which gives information about weather and terrain. Some GPS units with different resolutions are:

320×240
480×272

PC Interface
The portable models have a USB or serial ports which gets you connected to a PC. It enables you to download latest maps and system software. GPS units with USB and serial ports can be found at:

USB:
Serial port:
Bluetooth GPS that communicates with mobile device wirelessly are also available.

Built-in memory
With larger memory space one can store more route information and waypoints. Units with software that can transfer data from the unit to a PC can be used to gather more data than it can hold. So depending on how much map data and information you wish to store, you can select the units with the required memory space. You get various models with wide range of built-in memory space.

1 to 30MB
30 to 512MB
512 to 2500MB
2500 to 40000MB

Antennas
External antennas are used when stronger signals are needed. If in a vehicle the system cannot be placed near the window, external Antenna hookups can prove to be ideal solution. Choice of external hookups is most practical for hiking under heavy tree cover, under tall buildings or in any place which doesn’t have a good view of sky.
Built-in antennas are less prone to breakage and can communicate with more satellites.
Quadrifilar Helix- This is also an external antenna useful for situations where open sky is limited.
Flip up antennas too give strong performance.

Price
Under $200- You get good light weight portable navigation units in this range. Maps look great with reasonably timely route recalculations. Good value for money! Those of you looking for more memory space may check out models at higher range.

Between $200 to $312- You get better performance and features like anti glare, touch screen with good resolution. You also get good in-built memory space and battery life.

Between $312 to $416- Good screen settings, voice guided directions and overall good performance.

Between $416 to $1172- Accurate route guidance, easy to use and compatibility with Bluetooth cell phones are some attractive features of devices in the price range.

Happy GPS! Bye.

6 benefits of GPS fleet tracking include:

Increases Fleet Efficiency:
With GPS tracking data you can determine an individual or group’s average length of a service stop; or analyze a service stop vs. non-service stop; or the actual length of a service call or installation. Corrective measures based on this information gets job productivity up and wasted time and inefficiency down.

Can Help Lower your fuel bills:
GPS tracking information attacks high fuel bills in three areas: Controlling Speeding, Idling and Unauthorized Use. Tracking data is captured for all three items allowing fleet managers to take steps to address these and measure the results of their actions.

Can Help Lower Insurance Bills:
As a result, fuel consumption and costs can drop dramatically. Speeding increases your maintenance, fleet insurance premiums, fuel expense, gas mileage and your liability should an accident occur. With GPS tracking there is no need to rely on the public to report unsafe drivers. You will know how your vehicles are being operated and by whom.

Can Control Moonlighting of Employees:
GPS tracking units monitor who, what, where and when your vehicles are or have been. This puts controls on unauthorized usage and moonlighting. Can also help prevent theft of cargo.

Ensures Vehicle & Cargo Security:
Every year companies lose billions a year because of cargo thefts. Much of this happens during transit, before it is even delivered. Tracking systems can play a major role in preventing both vehicle & cargo thefts as well as aiding in recovery. Systems monitor every move & stop.

Can Resolve billing disputes:
Arrival and departure times are recorded. Determine exactly when your vehicle arrived and departed from a customer address.
