What My Satellite GPS Can Do That your Road Atlas Can’t
Christine Peppler asked:
Television is not the only “cool” thing using satellites these days. For anyone who likes to travel or wander, the GPS satellite navigation systems that have been on the market for a few years are handy on-the-road companions. Some automotive manufacturers offer GPS in select car models however GPS can also be purchased after market and can be operated outside of the car as well. Satellite GPS navigates through signals received from the myriad of satellites orbiting earth and is extremely accurate using the maps that are loaded into its memory.
So what does a satellite GPS device offer that a road atlas doesn’t? GPS satellite systems provide directions while traveling, generally through voice instructions which allow the person to keep their eyes on the road. No more pulling off to the side of the road to study a map, struggling to read illegible print, or trying to find just the right spot with only a dome light for illumination.
Satellite GPS devices are also “smart” as many can also provide updates on weather and traffic information and then assist in mapping an alternate route when barriers exist in the pre-planned route. This flexibility and problem solving make it an invaluable tool when traveling in an unfamiliar area.
Satellite GPS devices are also great to use when hiking, camping, cross country skiing, and participating in similar outdoor activities. Their small size and light weight make them a great tool outside of the car and are often recommended by outdoor enthusiasts and organizations for safety purposes.
Most satellite GPS devices sold in the US contain maps and points of interest such as airports, hospitals, and so forth to the tune of over one million locations. However, these devices aren’t limited to the boundaries of the US obviously. For those who wish to use the device when traveling outside the country, many devices have flash cards which can be used to download the appropriate maps corresponding with their destination making satellite GPS a great travel companion.
For many potential users an important consideration is ease of use. Many satellite GPS devices, such as the portable Sony Nav-U, are ready to use right out of the box. It has maps and over 1.6 million points of interest loaded into its memory. It offers a full color 3.5″ touch screen display and 2-way speaker system. Cost of an average satellite GPS device is in the range of $400 to $600 dollars but given years of good service and flexibility of use it would seem an excellent investment.
In the world of navigation or route finding, it seems that satellite GPS devices will eventually put basic road maps and compasses into the same realm as typewriters and carbon paper.

GPS History in Brief
Steve Kinder asked:
The GPS satellite system for navigation was designed in the 1970s by the U.S. Department of Defense. It started out as a global navigation system for military land-based and air vehicles, with some limited use for the civilian population. But today, the tables have turned – there are more GPS receivers used by civilians than by the military!
Back in the 70’s, the military employed a variety of navigation systems such as LORAN (acronym for Long Range Radio Navigation), VOR (acronym for VHF Omni-directional Radio) and OMEGA, and a need was felt for a more accurate navigational aid which would be functional all day, all year and everywhere on Earth, irrespective of day or night or weather conditions. The military’s needs were to navigate its airplanes, tanks and personnel reliably. At that time, the U.S. Navy and the Air Force were in the pursuit of developing systems that would meet such requirements with programs such as Transit satellite system, Timation satellite system and Project 621B. The Department of Defense eventually formed a Joint Program Office (JPO), which consolidated the developments to date in to what we know today as the Global Positioning System (GPS).
The first GPS satellite was launched in 1974, and the GPS satellite constellation was declared fully operational in 1994. The satellites were/are designed and built by Rockwell International, Boeing and Lockheed-Martin.
Though GPS was designed by the DOD for the military, they did include some capabilities that could be useful for the civilian community. The GPS satellites transmit encrypted signals, which only the military has access to. The satellites also transmit non-encrypted signals, which can be detected in both military and civilian GPS receivers. The civilian signal is referred to as the C/A code signal (Coarse Acquisition).
A key parameter that describes GPS capability is positioning accuracy, which simply put, is the accuracy of the GPS receiver user’s position computed in the GPS receiver. GPS system developers initially did not expect the civilian signal to provide position accuracy comparable with those obtained by the military signals. However, the designers soon realized that the civilian GPS receivers could employ several newly developed algorithms that could improve the position accuracy obtained in civilian GPS receivers dramatically. In order to limit the positional accuracy of civilian GPS receivers, they implemented degradations of the civilian GPS signal before being transmitted by the GPS satellites. The degradation capability is referred to as Selective Availability (SA). SA limited position accuracy in GPS receivers to ~50 meters. However, by late 1990s, President Clinton having realized the benefit of GPS to the civilian community, ordered SA degradation to be removed. With the removal of SA, the doors opened up for civilian users to use GPS for automotive tracking for driving assistance, fleet management, …….

Benefits of GPS Fleet Tracking Systems
Marcia Henin asked:
Global Positioning System also referred to as GPS uses satellite signals for tracking the location of a person or a vehicle. The system has gained wide popularity in a short time among the masses. There are many different types of GPS systems available and GPS fleet tracking system is one of them.
The major benefit of GPS fleet tracking system is that, it operates efficiently in both metropolitan as well as rural areas.
container tracking systems also help in terms of navigation. In the absence of a proper GPS system, you may not only drive in wrong directions, but will also waste a lot of time.
With a proper GPS fleet tracking systems in place, you do not have to ask for directions all the time in a new location. Thus, it saves a reasonable amount of both fuel as well as time. Another advantage of the vehicle tracking system is that, it regularly alerts the driver by keeping a track on the vehicle’s speed thus helping to prevent accidents caused due to rash driving.
By using a GPS fleet tracking system, you can also learn about your driver’s whereabouts during working hours and can guide him with routes.
GPS fleet management system also lowers the risks of employee frauds and vehicle thefts. It also reduces the insurance cost, because vehicles with GPS fleet tracking systems are less prone to thefts. This will help you to get auto insurance at a reduced premium rate.
Thus, GPS fleet tracking system is an innovative technology that will help your fleet business to improve the productivity as well as profitability.
The installment expense for a GPS fleet tracking system is a bit high, but the long-term benefits that it provides will certainly overweigh the high installation costs.

Initial GPS, Where Do You Find Them
Jim Kesel asked:
Does a GPS unit need a Garmin logo on its back to be considered an efficient device? The answer is of course not. In fact, when it comes to the retail industry, ‘name’ can often just be an excuse to add hundreds maybe even thousands more to a product’s price tag. Many consumers get caught up in the hype simply because through the television, Internet and magazines they’ve had a chance to become more familiar with the brand names. Well, there are plenty of GPS brands that are not as well-known that are still wonderful devices. This article will talk about one of them, the Initial GPS models.
Initial GPSes are some of the most hard-to-find GPS brands in the market. Perhaps this might be due to the fact that Initial Technology, the company making them, is actually a business geared towards making entertainment devices. This seems to show in a couple of Initial GPS devices, but in a good way. These models, the Initial GPS GD-72, (which costs $449.99), the Initial GPS GD-71, (which costs $469.99), and the Initial GPS GM-410, (which costs $229.99), are the only GPS units that actually offer built-in DVD players. The Initial GPS GD-72 and the Initial GPS GD-71 even look like portable DVD players. The Initial GPS GM-410, on the other hand, has an appearance typical to most GPS units.
As far as navigational capabilities, Initial GPSes are no different than any other type of GPS. The above-mentioned Initial GPS GD-72 and Initial GPS GD-71 along with the other non-DVD Initial GPSes, (including the $199.99 GM-350 GPS Receiver and the $379.99 GM-501 GPS Receiver), are pretty much the same when it comes to navigation. Their interface consists of colorized touch screens and Bluetooth technology for hands-free telephone calls. The devices include preloaded U.S. maps and 2 million points of interest. As far as directions, they are voiced, a feature common in many famous brands available on the market.
Initial GPS models offer a unique choice for those looking for more affordable GPS options. Not only are they pretty much standard when it comes to GPS navigation, but many of them even have DVD players. Such a feature allows one to save even more money, since portable DVD players by themselves can be hundreds of dollars. Truly, these types of Initial GPS models can almost be considered an all-in-one device, since they provide both GPS capabilities as well as DVD capabilities. The only challenge one will face if they do want to purchase an Initial GPS is where to buy one. The Initial Technology site doesn’t even offer the products for sale, and of the few sites that do, the more interesting Initial GPS GD-71 and Initial GPS GD-72 models tend to not be in stock. Even the average shopping comparison site seems barren when one tries to search for Initial GPSes. However, you will find that Target stores carry a full line of Initial GPS receivers. Another good source is the Internet and auction sites like eBay. No matter where you find them Initial GPS systems are easy to use and reliable.

What’s SiRFstar III?
Michelle_chow asked:
A modern SiRFstarIII chip based 20-channel GPS receiver with WAAS/EGNOS support.SiRFstarIII is a range of high sensitivity GPS microcontroller chips manufactured by SiRF Technology.GPS microcontroller chips interpret signals from GPS satellites and determine the position of the GPS receiver.
GlobalSat SirfStar III CF GPS receiver
Features
SiRFstar III receiver and integrated antenna from UK company Antenova. This measures just 49 x 9 x 4mm.The SiRFstarIII chip is distinguished from earlier SiRF chips and from GPS chipsets made by other manufacturers (Garmin or Trimble Inc for example), largely due to its ability to acquire and maintain a signal lock in urban or densely covered forest environments, and its faster Time to First Fix (TTFF), the time it takes for a GPS receiver to lock onto the satellite signals and determine the initial position. The enhanced abilities of the SiRFstarIII chips are made possible by several features:
SiRF Star III based GPS receiver with integrated antenna. M10214 from Antenova, a UK company.
A 20 channel receiver, which can process the signals of all visible GPS and WAAS satellites simultaneously.
The chip consumes 62 mW of power during continuous operation. Assisted GPS can reduce TTFF to less than two seconds. This makes the chip useful for cell phone manufacturers supporting location services (such as the E911 legislation in the United States).
Receiver sensitivity of -159 dBm while tracking; GPS receivers based on this chipset have routinely performed better than receivers based on other chipsets.Reviewers have praised the SiRFstarIII chipset for its superior sensitivity and tracking capabilities.

Turn Your Laptop in to a GPS System
Richard Neesal asked:
A Global Positioning System (or GPS) is a satellite navigation system that works by continually transmitting high-frequency radio signals containing the time and location of a person anywhere on Earth. With miniaturized GPS units and fewer integrated circuits GPS technology has become economical and accessible almost to everyone. It really has changed the way we work and play.
Although it would probably amaze many people, it is possible to turn your laptop into a GPS system. In fact, there are many individuals who already found how easy to it to use their laptop as a GPS.
When a person has a laptop all they really need do is purchase the software for a GPS system and then configure the laptop according to the settings. Some software available already has the configuration worked into the software but can be a bit more expensive for some people to use. Also, there are those laptops that won’t work with certain types of software, so it is a good idea to make sure the laptop is indeed compatible with the software.
Most of the software for the GPS installation on the market today will only work with windows XP or newer version of Windows. However, you may still find some older versions that work with previous Windows versions. In addition, there are certain instructions that should be followed after the software is installed to get the best possible performance out of the laptop.
For example, the battery life on the laptop is only going to last for so long and then it will need to essentially be recharged. This is important thing to consider if you are going to rely on the laptop as a navigation aid. Sometimes turning certain features on the laptop off after a period of time if they are not in use by any programs that are running the laptop can lengthen the battery life.
There are several web sites via the Internet that offer information about the many different ways users can ultimately turn the laptop into a GPS system for road or general navigation use. Some of these web sites can also help or assist with installation as well. In some situations the software can be purchased via the web site on the Internet, depending on which web site an individual is at.
With a powerful laptop that is enabled with a GPS your road experience will turn into an adventure. As more people realize that the laptop can be transformed into these types of GPS systems, the idea will increase in popularity and more individuals will carry their laptop with them in the vehicles they are on the move.

GPS Tracking Using a Cellphone
Steve Knowles asked:
The GPS-enabled cellphone market is forecast to more than double by 2012, hitting 550 million units. Put it all
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.

The GPS Navigation System
Geovani Stoner asked:
The GPS Navigation stands for the worldwide Positioning scheme, which is to time, the only functional worldwide Navigation Satellite scheme in the world. GPS Navigation successfully manages through the coordination of satellites orbiting the sphere. GPS Navigation Receivers, which are the earth permanent plans in GPS navigation, synchronize with 24 channel Earth orbiting satellites, allowing GPS Navigation Receivers to ascertain its strict scene, as well as its flow bearing and the quickness it is vacant, or slightly the quickness, scene and bearing the abuser-on-hand with it is vacant.
As an aid to navigation excursions, GPS Navigation organisms justly function well. GPS Navigation Receivers are the end-abuser border for the GPS organism. The number of channels a GPS navigation receiver ropes, says a lot about the number of satellites the GPS navigation receiver could actually join to, or observe, simultaneously.
One of the earliest places that enjoyed widespread GPS navigation would have to be aviation of all sizes. New innovations in GPS navigation devices are coming out monthly. Combined with transmitters, GPS has been used to track stolen property.
The GPS navigation system, however, forms the bridge between safety and entertainment features. Some GPS navigation systems are built right into a vehicle, while others are handheld devices that mount on your dashboard. There are many accessories available for GPS navigation systems. When buying a GPS navigation system, you should consider such factors as screen size and whether you need a color or monochrome system.
Handheld GPS navigation systems, auto navigation systems are popular items that are being used by everyone from outdoors enthusiasts to average drivers. There is a whole lot of power and capability packed into a GPS navigation system. GPS is the short form of Global Positioning System. The primary function of a GPS receiver is to pinpoint its actual location on earth using the signals it intercepts from GPS satellites. A GPS navigation system will save you money at the fuel pump. Be sure the GPS navigation system has the map of your country included.

Using Gps As A Source Of Accurate Time
Richard n Williams asked:
The Global Positioning System (GPS) is an increasingly popular tool, used throughout the world as a source of wayfinding and navigation. However, there is much more to the GPS network than just satellite navigation as the transmissions broadcast by the GPS satellites can also be used as a highly accurate source of time.
GPS satellites are actually just orbiting clocks as each one contains atomic clocks that generate a time signal. It is the time signal that is broadcast by the GPS satellites that satellite navigation receivers in cars and planes use to work out distance and position.
Positioning is only possible because thee time signals are so accurate. Vehicle sat navs for instance use the signals from four orbiting satellites and triangulate the information to work out the position. However, if there is just one second inaccuracy with one of the time signals then the positing information could be thousands of miles out – proving useless.
It is testament to the accuracy of atomic clocks used to generate GPS signals that currently a GPS receiver can work out its position on earth to within five metres.
Because GPS satellites are so accurate, they make an ideal source of time to synchronise a computer network to. Strictly speaking GPS time differs from the international timescale UTC (coordinated Universal Time) as UTC has had additional leap seconds added to it to ensure parity with the earth’s rotation meaning it is exactly 18 seconds ahead of GPS but is easily converted by NTP the time synchronisation protocol (Network Time Protocol).
GPS time servers receive the GPS time signal via a GPS antenna which has to be placed on the roof to receive the line of sight transmissions. Once the GPS signal is received the NTP GPS time server will distribute the signal to all devices on the NTP network and corrects any drift on individual machines.
GPS time servers are dedicated easy to use devices and can ensure millisecond accuracy to UTC without any of the security risks involved in using an internet time source.
