ABSTRACT
Mobile positioning technology has become an important area of research, for emergency as well as for commercial services. Mobile positioning in cellular networks will provide several services such as, locating stolen mobiles, emergency calls, different billing tariffs depending on where the call is originated, and methods to predict the user movement inside a region. The evolution to location-dependent services and applications in wireless systems continues to require the development of more accurate and reliable mobile positioning technologies. The major challenge to accurate location estimation is in creating techniques that yield acceptable performance when the direct path from the transmitter to the receiver is

2.1 ARCHITECTURE OF A GEOLOCATION SYSTEM
An example of geolocation system architecture [KOS00] is shown in Figure. As we said earlier, in order to fix a call the subscriber we are calling must be located accurately. A geolocation service provider provides location information and location aware services to subscribers. Upon a request from a subscriber for location information about an MS, the service provider will contact a location control center querying it for the coordinates of the MS. This subscriber could be a commercial subscriber desiring to track a mobile device or a PSAP trying to answer an E-911 call. The location control center will gather information required to compute the MS’s location. This information could be parameters such as received signal strength, BTS ID, TOA of signals, and so on that we discuss later. Depending on past information about the MS, a set of BS’s could be used to page the MS, and directly or indirectly obtain the location parameters. These are sometimes called Geolocation base stations (GBSs). Once this information is collected, the location control center can determine the location of the mobile with certain accuracy and convey this information to the service provider. The service provider will then use this information to visually display the MS’s location to the subscriber. Sometimes the subscriber could be the MS itself, in which case the messaging and
A. WiGle fullform is Wireless Geograhic Logging Engine.The primary reason for this site is accustomed to social affair data about various remote hotspots around the world.Any client can enlist in this site and transfer hotspot information like GPS Co-ordinates , SSID and MAC locations and encryption sorts that are utilized as a part of various sorts of gadgets. Gathering these data
Answer: - Coordinate system is actually a reference system which represents the geographic locations, images, GPS (Geographic Positioning System) locations present in a common geographical framework. Hence these coordinate systems allows the geographic datasets to use the common locations for the purpose of integration.
With so many web and mobile applications available today, it is difficult to find a particular one that impacts more individuals and businesses than others. Many applications perform one or two tasks well, but I believe Google Drive is one of those applications that anyone can find useful. Whether you’re a student or a business person, Google Drive can be of use in anyone’s life.
it's free app for iOS and Android users your location by GPS to make you
There are three ways for anti-GPS spoofing. These are cryptography, signal-distortion detection, and direction-of-arrival sensing. However, use of one method is not enough. Combining strategies is the sure way to secure a countermeasure for spoofing. Cryptographic method allows the users to authenticate signals on the fly. An example of cryptographic technique is the use of PRN codes for the civilian receivers. PRN codes are unpredictable that is why a spoofer cannot grasp the codes ahead of time. In addition, there is still a need of verification of each new signal. Every civilian receiver carries an encryption key similar to the ones used by military receivers. It is difficult for the attackers to obtain the keys correctly. Nevertheless,
Each photograph that you take is geo-tagged and this function helps you to know where you
The service radio coverage is correct, if the service area is secured by the base stations. The service area is secured, if the unification of radio cells of every base station contains the whole service area (Svilen, n.d). The radio cell of a base station is a part of the space around it, in which a portable station watches the base station with radio signal strength adequate for correspondence (Svilen, n.d). The adequate radio signal strength in the service area is a basic prerequisite for the portable stations to be able to access to the WMN. The radio coverage service guarantees this adequate signal strength in the service area (Svilen, n.d). A service location is a state of the service area, determined by its directions. A service location
In conclusion, geocoding is a very powerful tool that matches addresses found, to actual, real, precise locations found in the reference data. The choice of the reference data is essential in the success of the geocoding. It will affect the accuracy of your results. The most important aspect of the process of geocoding is having three components. They are the address table, reference data and an address locator. The address locator is created by have a reference file and a locator style. With geocoding you can display the address location using the address locator, which is usually a point feature. Once this is accomplished, the address elements (address name) can be compared against the elements in the reference file. The geocoding process will construct a table with all matches, un-matches and the ties of these
Tivonne, you are absolutely correct when discussing GPS for tracking semi trucks with materials. A local trucking company that hauls materials to our facilities, calls our shipping and receiving departments when their trucks GPS indicates they are within 15 to 30 minutes away. This is helpful for our employees to be ready with paperwork, crews to unload, and fork truck/crane to remove cargo. This phone also can alert the individual who ordered the materials, so they can inspect on the dock to accept or decline cargo. If the materials fails visual inspection, the cargo can stay on truck to be sent back.
1. By using GPS device, it is possible to track the location of soldiers when it is needed.
Geolocation mobile based is a perfect for locating the nearest shopping mall, or bookstores, where the mobile phone is able to travel with the individual. The desktop system is bound to a place of business, or home. And the data is not able to be changed as the individual changes their location same
Department of Defense. Transmitting information that the signal picks by circling the earth twice a day in a constant speed (“What is GPS?”), like Google Earth. This helps to also pick up a person’s real time movement by adding additional tracking of people, like sex offenders, and where their location is. Tracking where and when a crime takes place is also a job for GPS. GPS is more reliable system of tracking than the Radio frequency, or the RF system
In this high-tech environment of the 21st Century, most everyone who drives a car or carries a cellphone has heard of the Global Positioning System (GPS), but few could provide details on the origin, development and many uses of this system, outside of basic everyday navigation. This paper will explore the origin and development of the Global Positioning System, as well as analyze various uses of this system. Some of the practices include Military use, surveillance of those convicted of violent crimes, tracking of wildlife, and location based services as it applies to the Cellular Communications Industry. This paper will also explore the reality of the Global Positioning System as it relates to a Christian worldview.
Today the accuracy of GPS navigation is not questioned, however, there are still some Applications that use GPS to plot routes between two points and can be very inaccurate because it is hard to determine the difference between locations [5]. For example if you are on a trail that is not registered a GPS could give you an incorrect route. Also a GPS receiver will give inaccurate readings in a forest or a city with tall buildings because satellites have to send clear signals to GPS
GPS has made our lives so much easier. We don't have to print out directions before heading to an unknown address. GPS-enabled devices we carry with us daily allows us to travel freely without worrying about getting lost. There are also a number of GPS devices to help us keep track of our children. It's a dangerous world out there, and at any moment, we might need to know where our children are located.
