...Running Head: DIFFERENTIAL GLOBAL POSITIONING SYSTEM 1 Differential Global Positioning Systems Clay Guida Southern Illinois University DIFFERENTIAL GLOBAL POSITIONING SYSTEM 2 Global Positioning Systems (GPS) have become one of the greatest innovations of the modern world. 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...

...Global Positioning System (GPS) receivers and radios are of immense use even at an unassuming place such as an amusement park. This case study discusses how a family with children visited Disneyland and Disney's California Adventure Park taking along with them a GPS receiver. This GPS receiver was a Garmin seventy six cs, and came with four GPS radios that were Rino five hundred and twenty HCx. The family initially used the GPS receiver with the standard basemap, and later with the StoneMaps. The case study tries to understand how the family used these units and made good use of the radios. These radios turned out most useful as a means of communications given they were often in a crowd and split up from time to time to explore different amusements. The GPS receiver was also a help because children tended to wander away. The paper highlights how the equipment maximized the family's time and fun by offering a ready guide around the place, activities and a tracking and communication system that involved the children as well. It discusses the details offered on the maps. The paper points out that the maps are uncluttered and they are visually clear and appealing on a color screen. The available maps are also compatible with older units. They offer an overview when zoomed out and display details when zoomed in. The paper also offers details on the waterproof features of the Rino GPS units along with the carry a backlight for use at night...

They can now be hand-held and are highly prominent on roads. This is particularly noticeable in taxis, as most cabs are now fitted with some form of GPS device and many fleets have enforced mandatory GPS policies. This document analyses the impact and worth of refitting a fleet of taxis the size of Canberra Cabs with new portable GPS devices. A series of systems analysis techniques were applied in the analysis of the devices in order to reduce the complexity of the components. A major period of device improvement was identified as the time between 2007 and 2009 based on a diffusion of innovations analysis. The analysis of two particular devices, the TomTom XL 310 (2007) and the Garmin Nuvi 1350 (2009), were used as a comparative measure of the improvements made in the time period. The devices chosen for analysis were ergonomically assessed in terms of their user interface.

What technologies are required to facilitate the success of PNDs? PND’s have become very popular in both handheld and vehicle models. These personal devices allow the users to not only determine where they need to go but also where they are and most have a memory which allows the user to save locations to their favorites. If they are connected to the internet they can be updated regularly with new locations to search for within their memory like restaurant’s, gas stations, and various other stores and community locations. PND’s work using GPS navigation satellites to gain their respective GSP coordinates. With these coordinates the internal system can place them on the map that have been installed within the PND and shows the user where they are in relation to other locations and can even give the best path from point A to point B. 2. Who are some of the leaders in PNDs? What are the likely factors that will contribute to winning in this marketplace? Among the top PND’s are Garmin, Tom Tom, Magellan, and Motorola. The PND that I have had personal experience with would be the Garmin. Garmin produces rugged hand held models that are perfect for camping, hunting and hiking.

...aizan, elissa, suhailan, fadzlihasan}@unisza.edu.my ABSTRACT Various techniques that employ GPS signals such as A-GPS and GPS transmitters [4, 7] have been introduced with the hope to provide a solution for indoor positioning detection. We proposed the implementation of trilateration technique to determine the position of users in indoor areas based on Wi-Fi signal strengths from access points (AP) within the indoor vicinity. In this paper, percentage of signal strengths obtained from Wi-Fi analyzer in a smartphone were converted into distance between users and each AP. A user’s indoor position could then be determined using a formula proposed based on trilateration technique. KEYWORDS Indoor Position detection, WI-Fi, Trilateration Technique. 1 INTRODUCTION Global Positioning System (GPS) is a technology developed by United States of Defense (DoD) that has been used for military purposed. It is also the main technology that plays an important role in satellite navigation. The main purpose of GPS is to determine the position or coordinate of an object based on location, time and speed [2, 6] which provide Location Based Services (LBS) [5, 6]. Nowadays, the technology has been used widely in outdoor environment such as in navigation and coordinate measurements. GPS depends on satellites to communicate using radio signals. Common example of GPS receivers such as GARMIN, NAVMAN and TOM TOM are capable to determine the accuracy of a position...

...2.0 Situation Analysis 2.1 General Environmental Analysis (i) The economic forces The sales that generated by TomTom are impacted by the economic fluctuations of the market in which it competes. If the economic is downturn, it is limited the capacity for business and consumers to spend, as a result, the level of revenues for TomTom are going down. For example, the economic recession in year 2009 was brings a huge impact to TomTom. The economic recession in year 2009 is considered the “dark side” for TomTom, it brings a huge impact to them and enables TomTom almost go into troubles and crisis situation. Until the huge recession in 2009 has passed away, the economics of TomTom still unable to fully recover and the revenue is still affected. The economic recession has brought more impact on TomTom in term of their sales and revenue growth. It leads to a significantly dropping of the sales and revenue growth of TomTom, for example “on 22nd July 2009, TomTom reported a fall of 61% in its net income at the end of 2nd quarter 2009”. TomTom has a significantly dropping of their sales and revenue growth because there have a price war exist during economic recession, especially in mature industries of TomTom such as in US and European, it was affected the profit earned by TomTom. Besides that, another reason is almost customers were reducing their expenditures and avoid buying the unnecessary things such as devices since it is still seen as luxury products during economic recession...

...countries and territories around the world (UPS, 2015). The challenges associated with this problem and the information that required analysis concerned maintenance of its fleet. In the past UPS used to replace important parts every few years. This was the solution they used to ensure that its vehicles stayed on the road and in good working order. The new approach however, is to collect data from hundreds of sensors in each vehicle. They then use various algorithms to analyze that data from thousands of trucks to predict when a part is likely to break down. This allows UPS to save millions in maintenance costs and prolong the life of their vehicles (Forbes, 2015). Predictive analytics was used as part of the problem solving strategy. Fleet GPS tracking and telematics is used in over 11,000 delivery vehicles to collect data. Currently UPS has plans to...

...techniques result in a broad measurement and do not provide data in depth. Brown decided to take another approach by installing cameras to monitor users interaction with device. There were two studies in different settings. The first study consisted of 13 trips where the drivers interaction with GPS devices was monitored. Second study looks at how people use their smart phones to navigate and perform search as well as the role that mobile devices play in conversations. Summary In the first video, the driver follows the instructions issued by GPS, however during a turn, a passenger is crossing the street so she stops but GPS updates the current instruction with the next instruction. This doesn’t cause any problem because the driver knows when to stop and therefore don’t follow the GPS blindly. In this scenario, the sensor assumes the driver has completed the turn, even though they are just starting the turn. In the second video, the GPS issues an instruction but the driver ignores it and chooses his own route. These are both examples of using GPS however as a competent driver, we need to work out what the GPS is instructing and when is a good time to follow it. This is because GPS could get it wrong...

...GPS-to-GO Takes on Garmin Sharon Smith-Basey BUS 518 Project Leadership Dr. David Plumer Strayer University February 3, 2013 GPS-to-GO Takes on Garmin Analyze the personality and temperament of Joseph Thomas. Joseph Thomas is considered as an everyday manager who has grown up in the business of Global GPS and he commands great respect from his peers. Thomas has a full understanding of the makeup of workers at GPS. He knows too well how the workers are comfortable with working at their own pace and spending is of very little concern because their organizational culture is built around serving clients such as the government, who will fund their overruns and will allow years for development. Thomas is now functioning under new management, Michael Scott, a young, hopeful who plans to take on the strongest competitors in the consumer market. Thomas has the personality and temperament of an NT (Intuition-Thinking) Type. NT’s gather data consisting of abstractions and possibilities (N), which they filter through their objective decision-making process (T) (Rutledge, 2008). NTs have a driving force that is a never-ending quest for competence and this is demonstrated by Thomas and his peers as they desire to spend years on development and production, which causes them to pursue products not according to deadlines or costs because it is more about the soundness of the product. NTs are oriented toward continuous improvements and Thomas was scared to enter the faced-paced...

...Navigation Devices become popular? What technologies are required to facilitate the success of PNDs? A PND uses a GPS signals to determine the device’s location and display it on a digital map. Additional software brings features such as routing, driving conditions, suggested directions, ETA, interactivity, etc. The main features of PNDs that made them popular were convenience and accuracy of information. Before PNDs, to navigate one would need paper maps. Paper maps can become quickly outdated and cannot show current location. Users would have to know their locations in order to manually calculate a route to destination. A PND calculates the current location by triangulation of GPS signals and software calculates a route based on multiple criteria (fastest or shortest route, traffic conditions, etc). As the technology evolved, more features were packed in PND such as POI (points of interest). While a paper map can aid in manually generate a route to known destination, it cannot help finding a POI of which location is unknown to the user. 2. Who are some of the leaders in PNDs? What are the likely factors that will contribute to winning in this marketplace? If we are talking about dedicated PND, the market leaders are Garmin, TomTom and Magellan. However, if we are looking at the total number of GPS enabled devices that provide navigation features, then the combined sales of Samsung, Motorola, HTC and Nokia devices make...

...operations are services with mobile navigation solution , map content and services by the business units TOMTOM and TELE ATLAS.TOMTOM financial performance: looking at profitability and financial strength. From 2005 to 2007, the company had a consistent growth in revenue sales with a corresponding increase in net income. This changed from 2008 with a decline in sales revenue of 3.7% and a net income decrease of 136%. This can be accounted by the downturn of the economy but also indicates that TOMTOM did not change its strategy quick enough to absorb the changes in the economy. Sales revenue further decreased in 2009. Also look at competitive strength, TOMTOM is suffering from continuous pressure from competition and decrease in retail prices of GPS units. GARMIN is still the leader with market share of 45% while TOMTOM has a market share of 24%. Based on the above, TOMTOM has a competitive strategy but not a total winning strategy. They need to look at the industry and be more pro-active at market changes and other threats which they identified. TRENDS: Demand for portable navigation devices have declined as traffic and mapping functions are becoming an almost standard feature in cars and mobiles. It will thus look like these device’s market has reached its saturation point. It would seem that more focused is placed on fleet tracking in the satellite navigation industry and companies need to shift focus and adjust their strategies accordingly. Other market which is still available is...

...Objectives a. To study on the underlying knowledge used in the development of the GPS and how and why the GPS was developed. b. To research on the use of the GPS including the profile and type of user, the purpose it is used for and the developments together with new knowledge created through the use of GPS. Problem statement In this developed society, it is obvious that mankind has arrived at yet another golden era with rapidly advancing technology. The 21st century has appeared that human are at busiest to compete to gain wealth by exploiting all possible resources. However, busy lifestyle has caused issues such as traffic congestion. Time always appears to be a resource easily hit scarcity. This era where information is the riches has invoked the demand of mankind on a tool to navigate so that time will not be wasted when they are lost in traffic. Therefore a tool to guide direction is developed and introduced to the society. Introduction The Global Positioning System (GPS) is selected as the tool in this assignment. Though GPS appears to be a common tool in the society, not everyone understands the process of development gone through by GPS. Global Positioning System is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial...
