What do I Need Know About Bluetooth Wireless GPS?

If you are in the market for a Bluetooth wireless GPS system and have no idea where to start then I am here to help. First thing you need to know is there really is no best Bluetooth GPS, but the certainly are some bad ones out there. Before you decide on what to get for your Bluetooth wireless GPS, you need to understand some of the basics as to how the system works and why a high quality unit is needed to maintain and accurate location on the GPS network.
Basics Of The Bluetooth Wireless GPS
There are three main components to the GPS system. The first component is the satellites that orbit the earth. Currently there are 31 satellites in orbit around the earth that support the GPS system. These satellites keep in constant contact with each other updating the time between each and there location. The reason for this will be explained in a moment as it is vital to the functioning of the Bluetooth wireless GPS system.
Each of the satellites sends out strong radio signals which can be picked up by your Bluetooth wireless GPS unit. The unit can then calculate those times against its own internal clock to judge the distance to each of the satellites and then triangulate its own position. The satellites stay in constant orbit around the earth and make two orbits per day. This means that the whole network is in constant motion and continually staying in contact with each other to keep things updated.
The next component is the ground management portion. The US Air Force continually monitors the satellites and stays in communication with them to assure that they are in the right position and transmitting the right information. This is a constant monitoring system that lets them know what the health of the system is up to date and right so that your Bluetooth wireless GPS can function properly.
The third component of the system is your Bluetooth wireless GPS device. This device has a processor in it that calculates all the information being sent by the satellites and checks it against its internal clock. It is imperative that the processor and clock are of the highest quality to ensure an accurate reading. In addition, having a unit that is rugged and can handle getting wet or being dropped is also important because more than likely when you need it most you not be in the most hospitable environment. It is for those reasons that getting a high quality unit is very important. There you have, several strong reason why getting a high quality unit is important.

What Are the Components of a Bluetooth GPS System?
July 25th, 2008 Subscribe To Our Feed
There are many different things involved in a Bluetooth GPS system. Within the Bluetooth GPS system there are three segments – the space segment, a control segment, and the user segment. This article is going to take a look at all three segments so you can better understand how your Bluetooth wireless GPS works. A Bluetooth GPS system is one of the greatest advances in modern technology that we have had in the last decade.
The Three Parts of a Bluetooth GPS System
The space segment comprises the GPS satellites in orbit around the earth. These satellites continually broadcast radio signals with information down to the GPS systems around the world. In addition they stay in contact with each other constantly updating each other as to where their positions are. The original design called for 24 satellites in three orbits, but the current design has these satellites in six planes with four satellites each.
Each satellite completes one orbit per sidereal day. Currently there are 31 actively broadcasting satellites in the GPS network. The additional satellites have improved the precision of Bluetooth GPS navigators by providing redundant measurements. A key component in the Bluetooth GPS system, the satellites is what makes it all possible
The control segment of the Bluetooth GPS system corresponds to how the satellites are monitored and tracked. The US Air Force Space Command master control station receives information from bases around the world and coordinates the position of the satellites and synchronizes them with atomic clocks to ensure a reliable network. The updates are created by a Kalman filter which uses inputs from the ground monitoring stations, weather information and other inputs.
The user segment is the portion that your Bluetooth GPS navigator takes up in the GPS network. These are composed of an antenna tuned to the frequencies sent out by the satellites and have receiver processors to analyze the data. In addition the units need to have a highly stable clock to base all of the calculations off of. They are also labeled with how many channels or satellites they can connect up to. Bluetooth GPS navigators today typically have between 12-20 channels.
So there you have it, the basics of the Bluetooth GPS system. There is a lot more to it of course, but this should you a good idea of how it all comes together. Now you have a better idea of how it all works, hopefully you can put it to good use.

The Garmin GPS 10: A Bluetooth Enabled GPS Review
July 23rd, 2008 Subscribe To Our Feed
I have looked at several different Bluetooth enabled GPS devices and this article is going to take a look at the Garmin GPS 10. This is a very popular Bluetooth enabled GPS device so I would like to see why it currently is so popular and what separates it from the crowd.
The Garmin GPS 10: One of a Kind Bluetooth Enabled GPS Device
The GPS 10 from Garmin is an add on box that will turn your PDA or Bluetooth ready cell phone into a GPS device. Compact, lightweight and waterproof the GPS 10 will mount inside or outside you vehicle and send GPS satellite signals to your Bluetooth wireless laptop or any other Bluetooth ready device. What this means is that the Bluetooth enabled GPS can work just about anywhere and deliver high quality maps and use navigation software to plot your route so you can focus on what to do when you get there.
This device has intuitive software that makes getting places easier than ever before. Just type in where you want to go and the navigation software kicks in to give you turn by turn directions to your locations. In addition it will use voice prompts so you can truly use it in a hands free mode. In addition to this the Garmin software provides you with points of interest along the way so that you can find a place to eat, a place to sleep, where to get gas and much more. This device makes trups a breeze and you never will get lost again.
It includes a magnetic mount and hook and loop fastener to mount so it installs easily in just about any vehicle. The battery is a rechargeable lithium ion battery provides up to tweleve hours of continuous use so that you can rest it assured it will not die when you need it most.
There is also a 12 volt adapter provided for easy and convenient recharging. The wireless portion of the Bluetooth enabled GPS device can transmit signals up to thirty feet so that you can move you device away from the Bluetooth enabled GPS unit and still get signal. It is the perfect way to set up a Bluetooth GPS system.
The beauty of this the Garmin GPS 10 is the different devices it works with and how easy it is to set up. The only down side to it is its cost. At a little over $200 it is an expensive, but worthwhile addition to the family.
