...GLOBAL POSITIONING SYSTEM (GPS) ABSTRACT : Modern technology offers us an affordable mechanism called “GPS” which can help us find our way in situations like lost in a completely unknown place, hiking, snowmobiling, snowshoeing, mountain -biking, fishing, cross-country skiing, ORV expeditions, hunting and many others. GPS tells us exactly where we are on the planet at any time. It can do this with precisions ranging from exact precision to points within a 40-foot range. These variations dep end on the model and type of the GPS receiver you have. GPS is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. GPS uses these satellites as reference points to calculate positions accurate to a matter of meters. In fact, with advanced forms of GPS you can make measurements to better than a centimeter! In a sense it's like giving every square meter on the planet a unique address. GPS receivers have been miniaturized to just a few integrated circui ts and so are becoming very economical. And that makes the technology accessible to virtually everyone. These days GPS is finding its way into cars, boats, planes, construction equipment, movie making gear, farm machinery, even laptop computers.

...Running head: GLOBAL POSITIONING SYSTEMS Global Positioning Systems BUSI512: Managerial Information Technology Key Term: Global Positioning Systems Definition: According to Haag, Baltzan, and Phillips (2008) a global positioning system (GPS) is “a device that determines current latitude, longitude, speed, and direction of movement.” (p. 188). According to Dictionary.com (2008), a global positioning system (GPSP is “a global system of U.S. navigational satellites developed to provide precise positional and velocity data and global time synchronization for air, sea, and land travel.” Article Summary: “Secure Tracking for Critical Applications” by Chris Wullems, Alessandro Pozzobon, and Oscar Pozzobon In their article, Wullems and the Pozzobons discuss the importance of safeguarding Global Position System (GPS) tracking applications against security threats. They explain how users should be educated on the weaknesses in the technology so they can be aware of the proper procedures and tools to protect themselves. The authors start off by explaining the safety and security advantages of GPS technology with regards to vehicle tracking and remote monitoring systems. After briefly discussing those advantages, they then segue into the downside of the technology, and the inherent dangers involved in failing to adequately secure the technology. They refer to the technology as “a double-edged sword” without adequate...

...Global Positioning System was developed by the United States' Department of Defense. It uses between 24 and 32 Medium Earth Orbit satellites that transmit precise microwave signals. This enables GPS receivers to determine their current location, time and velocity. The GPS satellites are maintained by the United States Air Force. GPS is often used by civilians as a navigation system. On the ground, any GPS receiver contains a computer that "triangulates" its own position by getting bearings from at least three satellites. The result is provided in the form of a geographic position - longitude and latitude - to, for most receivers, within an accuracy of 10 to 100 meters. Software applications can then use those coordinates to provide driving or walking instructions. Getting a lock on by the GPS receivers on the ground usually takes some time especially where the receiver is in a moving vehicle or in dense urban areas. The initial time needed for a GPS lock is usually dependent on how the GPS receiver starts. There are three types of start - hot, warm and cold. The hot start is when the GPS device remembers its last calculated position and the satellites in view, the almanac used (information about all the satellites in the constellation), the UTC Time and makes an attempt to lock onto the same satellites and calculate a new position based upon the previous information. This is the quickest GPS lock but it only works if you are generally in the same location as you were when the...

...Global Positioning Systems (GPS) Historical development/context of the technology In 1993, the final satellite was launched to complete the network of the 24 satellites that make up what is now known as the Global Positioning System. Because of these, a person can purchase a little device that has the capability to track and verify their exact location within a few hundred feet. This fantastic technology only became available because the combination of scientific and engineering advances, especially the development of the atomic clock. The atomic clocks are precise within a billionth of a second. The development of the atomic clocks were important because the scientists were searching for answers about the nature of the universe. In the development of the atomic clocks, the physicists were unaware that one day their findings would lead to the global system that we use today. For centuries the stars and the sun were the only way people could navigate or to find their way. Even after clocks were developed, it was possible for people to find their longitude but even with the most accurate instruments, exact locations were only good within a few miles. The Soviet Union launched their first satellite, Sputnik on October 4, 1957. This new technology did little more than orbit the earth every 98 minutes. It was not equipped with any scientific equipment although it did contain a single radio transmitter, which made it easy for the United States to track its path. The United States...

Simply put, your personal guide to anywhere in the world. It can accurately get a fix on your position to within 100 meters. This is where most people would say that their GPS gets them down to ten meters or less, and they would be right. But it is GPS in coordination with the Differential Global Positioning System (DGPS) that gets them that accurate of a location. To understand this we must start from the beginning and go over GPS’s history. From there we will take a look at what causes some of the inaccuracies that GPS can. Then we can see how DGPS counters these and gives you the most accurate reading you can have. Differential Global Positioning System, GPS’s right hand man for accuracy. To understand how a DGPS helps a GPS we start at the beginning of it’s short history. Though made for use by the United States government, it was the Soviet Union that launched Sputnik in 1957 and gave us the idea. After the launch, Massachusetts Institute of Technology (MIT) researches observed that they could pick up the radio signal that Sputnik was producing. They also realized that the sound of this transmission varied with the...

Today many civilian GPS users have come to conflicting arguments as to whether or not GPS is here to help or hinder us. Between foreign nations such as China working to have successfully launched 35 satellites by 2020, and Superior court trials arguing violation of privacy… Has GPS found a competitor? What GPS does for us GPS is used daily for coordinating airliners (NextGen), city transit, package delivery, keeping track of our children as well as felons under adult supervision by ankle monitor. In many search and rescue situations, natural disaster and criminal monitoring or investigating, time is as critical as life or death.

Case Analysis summary Terracog specializes in high-quality global positioning systems. They are skilled at translating market and user feedback into outstanding products. Their GPS line of products were the finest in the market, applauded for its durability, navigational accuracy and value added features. In October 2006, Posthaste launched BirdsI, a handheld GPS that displayed satellite imagery, and it took the market by storm. Terracog had not anticipated such response from the market as they felt the users we smart enough to choose performance over graphics. The large response from the market for Posthaste’s BirdsI saw Terracog decide to launch Project Aerial by October 2008, it very own product with satellite imagery. As time was a constraint to get the product in the market, it was decided to redesign the existing GPS platform. The Design team provided the product design as requested by sales team by December 2007. Initial cost estimates of $550 provided by production department were too...

...Emma Richardson is in a dilemma whether to go ahead with the Project Aerial or not. The poor decision making process is one of the main reasons for the dilemma caused. Had the management of TerraCog not ignored the idea of shifting to satellite imagery as soon as Posthaste did it, the damage would have been much less. The organisation suffers from inefficient group structure. The decisions were not made in the right manner. When customer requests increased, Richard Fiero on his own decided to change his mind on satellite imagery, without discussing it with anyone else. Now the product development team is not happy with the decision made because it feels that there are several other exciting projects that are being compromised upon. Moreover, with a decision of go/no-go to be made by Emma, the large size of the group involved again threatens to thwart the decision making process. The inter department conflicts add to the dilemma. The sales team headed by Ed Prior feels the new product Aerial should be priced below $425 to capture the lost market share to the competitors. The design team headed by Allen Roth, redesigned within the existing GPS platform so as to speed up the development process and avoid costs of new moldings and major configurations. As per their estimate of the pricing team, the price for sale would, at the minimum, be $475. The price is quite too high for the sales team to consider. The design team has pressed the production team to reconsider the price estimates;...
