The main purpose of your portable GPS unit is to tell you precisely where on earth you are at that particular moment. This device can do this by triangulating your position based on information it receives from GPS satellites orbiting the earth.

With signals coming from three satellites, your portable GPS unit can calculate and tell you your 2D location in terms of latitude and longitude (will get to these terms in a moment). With four or more satellite signals, your GPS device can tell you more information about your position including how high you are from sea level or what is technically called altitude.

Once your portable GPS unit locks in your position, it can then track your movement as well as give a whole bunch of other information like your speed, bearing, distance to your destination and more. Oh yes, it can also play your favorite MP3 files while youre at it.

Portable GPS Terms You Need to Know

As an entrepreneur, it would really do your business image some good if youre familiar with all the nooks and crannies associated with the product youre selling. You can start by knowing the following portable GPS terms by heart.

* Longitude

There is an imaginary line running from the North to the South Pole which passes through Greenwich, England. This line is called the Prime Meridian. An incremental distance measured in degrees from the east or west of this line is called the longitude.

* Latitude

Just like the Prime Meridian, the Equator divides the world into a northern and southern hemisphere. Measured distances either on the north or the south of the equator is called latitude.

* Elevation

Your elevation is a measure of your distance, either above or below, the mean sea level.

* Multipath Error

GPS signals can sometimes bounce off tall buildings and mountains before these signals can ever reach your portable GPS receiver. This would cause problems in the accuracy of the signals you receive resulting in multipath errors.

* C/A Code

Civilian users of portable GPS receivers like you receives standard positioning signals called Coarse/Acquisition Code or more commonly called C/A Code. These signals can give your fix position with an accuracy of 100 meters or less.

* L1

There are two radio frequencies transmitted by GPS satellites and the first one called L1 transmits at 1575.42 Mhz and carries the C/A Code, P-Code and other nav messages.

* L2

The second set of radio frequencies from GPS satellites transmits at 1227.6 MHz and carries only the P-Code.

* OS

Just like a basic computer, the basic software that controls your portable GPS receiver runs through a specific Operating System or OS.

* Cracked Software

Your portable GPS device functions with the use of a GPS software. This software is licensed and sold by manufacturers. Hackers can sometimes remove the security coding placed by software manufacturers, resulting in cracked software. This is mostly prevalent in portable GPS units sold by Chinese traders.

* Assisted GPS

To boost the performance of portable GPS systems, cell phone networks can be utilized using Assisted GPS or AGPS.

* Warm Start Up Time

This is the time it takes for the portable GPS receiver to start navigation using the information during your last use, which is stored up in its memory.

* Cold Start Up Time

This is the time it takes for the portable GPS receiver to start providing position updates even without store information in its memory from previous use.

* Maximum Positional Altitude

This is the maximum altitude where your portable GPS receiver can function accurately and give you accurate coordinates. Some portable units like GPS watches can have its maximum elevation set by the user. The unit will alarm once the set altitude is reached, as in the case of mountain hikes and climbing.

14* Recapture Time

This is the time it takes for the unit to recover and interrupted signal without powering your unit off.

* Position Sensitivity

This sensitivity determines how fast your unit can search and process GPS signals to give you an accurate fix of your location.

* Data Update Rate

One thing that you should remember as a portable GPS device user is to have updated maps and other directional information in your unit. How fast your unit can update information depends on its data update rate. Higher-end models have auto update features that updates live traffic feed every 5 minutes for more accurate driving information.

It would be to an entrepreneurs advantage if he is well versed in the terms, functions and features of the portable GPS navigational devices he is marketing. Customers would be more comfortable in dealing with someone who knows much about the goods he is selling and portable GPS devices falls in the same category.

In-Car Satellite Navigation Units – What Features to Look For When Buying a GPS Unit

GPS Tracking Devices Tutorial: Understanding A-GPS

By Rose Li

 GPS tracking devices permit you to pin down an exact position on Earth as given by signals from a sequence of orbiting satellites. They receive the signals and then display coordinates for you to check on the computer.

GPS tracking devices are starting to become increasingly popular as they can be employed for plenty of different purposes that anyone would find useful in some shape. Imagine having the ability to monitor your new car’s location or perhaps know where your teenagers truly are when they say they’re going to a friend’s house to study. Now you can with GPS tracking devices. helped GPS is a way in which a GPS system’s start-up time can be colossally improved. If you have ever exploited a GPS device then you may know that when you turn them on it takes some time for them to ‘lock on’ to the satellite’s signal. Depending on where you are this may be very fast ( in an open area ) to rather slow ( in the middle of the town with many tall buildings or a forest ).

A-GPS uses the device’s mobile web connection to get further GPS info to ‘fill in the gaps’ while the device starts up and start using the satellites faster. It can do this in different ways. It can log in to a server which can have a better GPS signal which should then update the device in question or it can use the server to acquire a positional ‘lock on’ instantly, instead of waiting.

A-GPS would be good for a GPS tracking device which needs to be online and tracking its objective for as long a time as possible . Groups who would receive advantages from this :

The emergency services They could use A-GPS built into phones to find callers who are in a low signal area, so saving lives even in remote places.

Police or PI’s have to be able to monitor their GPS tracking devices at every point or they may be at risk of losing a suspect or missing some important info. people who live in urbanized areas will not have to fret about losing GPS signal in the middle of a journey due to interference due to tall buildings or bridges and tunnels.

Many GPS devices nowadays are provided with A-GPS, so if you are impacted by sluggish GPS performance then you should look for them and see how they can start helping you get superfast GPS all of the time!

GPS Tracking Devices Could Be Spying On You Now!

By Rose Li

 Around mid 2010 GPS tracking devices made the front page around the globe courtesy of a landmark political ruling in the usa.

Appeals courts in the states of California and Manhattan ruled the police and other law enforcement agencies could use GPS tracking devices to track the movements of suspects without a warrant.

On one hand this is good news as the police now have far more weaponry in their ar mory against drug-dealers, sexual deviants and violent villains, but on the other it has some practical concerns for regular, law-abiding citizens.

If you live in a certain state in the United States it suggests that you may very well be tracked by the police without even knowing it! They can place a GPS tracking device on your auto, as an example, without a warrant. Then they’ll know where you have been at every point.

We hope that they only target true wrongdoers, but mistakes have been observed to occur and how would you feel knowing that the police tracked your movements for weeks or perhaps months as part of acontinuing criminal inquiry only to discount you later?

The concern here is that the governing is potentially hazardous to people’s's privacy, but there are waysin which you can protect yourself

What goes up must come down, and in an analogous way, devices that receive a signal in orderto track someone may also be blocked.

GPS blockers are simple devices that give out a signal that blocks GPS signals coming down from the satellites. If you suspect that you’re being tracked, or likely to be, then you can activate one of these units and become invisible.

GPS blockers range from massive, high-powered units that will cover an entire office or house, to small portable units that have enough strength to cover avehicle for instance. Charge them, turn them on and you’re covered.

These devices are freely available ; however you want to double-check the law in your country before purchasing as they are in a legal gray area. Fortunately it’s the case that in most countries it’s legal to have them, but not employ them so buying them won’t be a problem.

They’re usually available from around twenty bucks for the smallest, transportable blockers, up to maybe 150 greenbacks for dynamic blockers that will cover a building. Theyare also often good for blocking GPS signals, mobilephone signals ormaybe both!

The ruling by these American courts is still open to plenty of debate and other states have disagreed and banned warrantless tracking by the police, so it’s definitely an issue which will not go away. If this has become somewhat satisfactory in the usa, one can expect warrantless tracking to spread to other Western states and even the wor

Although GPS-enabled smart phones are gaining a foothold in the portable navigation market, the standalone portable navigation device (PND) is far from dead. The fact is that today’s PND sports more features than ever to help you get from point A to point B quickly and safely – features like audible directions with text-to-speech (TTS), spoken street names, real-time traffic updates, Internet Connection for Points-of-interest search, and large easy to read screens, to name a few. The reason for GPS navigators will be so popular is that the GPS receiver will allow any person who uses a navigator to the most reliable and accurate information required of him, when he wants it where he wants it, was that anywhere on earth.

Data loggers are based on a technique, data collection or digital data acquisition. Data Capture is the process of recording or storage of real-world data or metrics in computer format. Different types of signals, temperature, humidity, etc. Can be monitored using data loggers. Logger such measure temperature, humidity and record them in its non-volatile memory as a log entry. GPS data loggers are capable of continuously logging their own location history over a longer period. Detailed recordings include

1. Time
2. Date
3. Location
4. Speed
5. Height

Built in flash memory and battery life allows for data logging over extended periods. With these functions, GPS devices can log their location precisely with an error of about 50m (error varied from unit to unit and from terrain to terrain).

This data loggers are gaining popularity among men mainly because of their compactness, their ability to track thousands   save way points and their accuracy reproduced stored data. Data can be exported in standard HTML, EXCEL, Google Earth KML, and RTF formats.

According to the definition of speed is simply the number of meters traveled per second in a particular direction (unit system may vary). The direction is important because velocity is a vector, the vector is simply a quantity with a direction. Velocity can be read in meters per second, kilometers per hour, miles per hour, feet per second and in the air nautical miles.

GPS navigators with data loggers gives you the wonders of technology, if you have it, you automatically have an edge on the latest gadgets navigation world has to offer.
