The satellite tracking technology intended for military applications during the 1980s is now made available to you through portable GPS navigational devices. These products have become extremely popular that entrepreneurs like you can jump into the bandwagon and cash in.
All you need to do for starters is to familiarize yourself with some of the most important portable GPS terms that you need to know if you want to go into business in this market segment. But first, take a look at how GPS systems work and gain some basic understanding that would prove useful for you in the long run.
How Does GPS System Work?
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.

Portable GPS Selling Guide: Making The Ultimate Unlocked GPS Devices Listing
By Rose Li
Almost everyone nowadays are into some form of gadgetry in one way or another, may it be media players, smartphones, eBook readers and tablets. Surely, these same people would go gaga over portable GPS navigational devices that not only give them location coordinates via satellite but all these additional features as well. As an entrepreneur, you can cash in from this amazing trend by making an ultimate listing of unlocked GPS devices on your website or e-store.
The Chinese Wholesale Market and Unlocked Portable GPS Devices
Starting an online gadget business selling unlocked portable GPS devices can be a real profitable deal if you would just learn the ropes and take heed of all the considerations. There are several Chinese wholesalers selling a wide variety of portable GPS device models that you can market and you can get them at amazingly low wholesale prices as compared to branded units from Europe and other parts of the globe.
On top of that, many of these wholesale Chinese suppliers even offer no additional shipping charges for bulk orders from them. That would give you additional savings which will directly go to your bottom line. Aside from that, a good number of these Chinese suppliers offer drop shipments for their products which basically means they ship products directly to customers once an order is confirmed by you no more worries about keeping stock!
These Chinese portable GPS devices are packed with all the advanced features one can find from these gadgets. You may be surprised that some of them even have more advanced features than some of the branded ones such as larger touchscreen displays and multimedia features.
The only problem with these devices is that they dont come with pre-installed licensed portable GPS software. This is necessary to minimize the cost of procurement for these products. Branded models usually come and are locked with proprietary licensed software and are sold at a premium. Unlocked units are not bound to a particular software application and can be installed with anything compatible. It would be up to the user, or the distributor, to provide licensed software for an additional cost.
Hardware quality can be comparable with branded portable GPS models. The only problem would be the lack or difficulty of technical support coming from these Chinese suppliers who are located half a world way. This would pose quite a problem with warranties as well as technical assistance should you be faced with a client brandishing a non-functioning GPS device.
Important Considerations if You Want to Sell Unlocked Portable GPS Devices
The great thing with wholesale Chinese portable GPS devices is the great leverage you can have with price tags. One thing to consider before putting price tags to your items is to compare prices from branded suppliers as well as other listings. The great thing here is that you can sell these at prices much lower than branded units, or even other listings for unlocked portable GPS device, and still make a killing.
When creating a listing, inform your potential customers at once that these unlocked units are sold without pre-installed software. It should be clear to them that software can be bought and installed separately, either through you (if youre selling software too) or through other sources at their discretion. It would be important though to include information about compatible software such as Windows CE in your listing, to give your clients and idea of what applications should work well and what will not with their units.
Another important thing to include in your listing is additional information about the hardware make-up of the models you carry. Important things to include are the type of processor, memory capacity, external storage, connectivity and other information that gadget-enthusiasts would be looking for. Look at other listings to see what they feature.
Marketing unlocked portable GPS devices can be a profitable business for you, as long as you make careful considerations about important things you should know before jumping in to the ballgame. Learning everything there is about your products, what your customers are looking for, and how you can present what you know in a very informative and engaging manner can surely win your customers support and their payments as well!
