The electronic tracker can be quickly given the position and velocity, but not to The target property of their geographical environment and spatial information associated with a description ，while the GIS is just to meet the requirements of this complementarily. Obviously, if only isolated the point of location information without geographic reference and other supporting information required, point position information on the application of logistics management is not very meaningful. With an electronic map(GIS technology) car, keep the city urban area map and save it up. It is accuracy and the amount of the information can be much higher than the printing of the urban traffic plan, but the car location achieved by drivers with the scene around by. Adding a portable GPS tracking, car location, driving direction, speed and other information can be displayed at any time in the electronic map.In short, using GPS and GIS technology in logistics information management system can use the G...

electronic tracking device can utilize location information to potentially provide a safer tracked environment allowing vulnerable people to continue with their daily activities, as much as possible. This paper presents the options for alert escalation. The aim is to provide a safety net, without triggering unnecessary alarms. The escalation procedure involves initial speech alert to the user, then a speech and vibrate alert to the user as a reminder; this is followed by a text message to an identified carer if the user has not re-entered the designated safe zone. Parameters for alert escalation can be tuned to individual circumstances. The user can seek help by getting directions from the current position to home or by calling a carer. The 21st century has brought an era of global population ageing. This will inevitably lead to an increase in the number of older people with dementia, with escalating costs for long term care. In 2010 it was estimated that worldwide cost of dementia ...

Applications requiring positioning in mobile networks have gained importance in recent years. Examples include not only LBSs, but also enhanced emergency call services such as the North American E911 and the newly defined Emergency Call (eCall), which is planned to become a European standard as part of the eSafety initiative of the European commission. Mobile network providers already offer LBSs along with positioning, although the accuracy and reliability of the present techniques do not yet meet the requirements of such services in all cases. One of the most popular positioning systems in navigation is the GPS tracker , which is satellite based, widely available and quite accurate, as long as the receiver to be localized and the satellites have an LOS connection. Since most common mobile phones do not support the GPS, network providers evaluate the position of the network’s base stations (BSs) which have connections to the mobile stations (MSs) to be located. The accuracy of the pr...

Despite similarities, there are some issues in the consistency GNSS issues as you know. For example, you may recall that the roll out of the new systems is not coordinated. In other words GPS ( GPS Tracking Device  ) Modernization, GLONASS replenishment, and QZSS and Galileo deployment have not been synchronized. Despite much cooperation there is no clear agreement among nations that launches and operational capabilities of GLONASS, GALILEO, GPS, QZSS, and Beidou will happen in the same time frame. Also there are differences between GLONASS and GPS regarding CDMA and FDMA. There are also differences in the time standards between the two systems. Not to mention the overlap between the GPS M-code and Beidou. It is important that these inconsistencies are worked out technologically because apart from the less sophisticated applications for GNSS interoperability will be required. For the full potential of the system to realize multiple GNSS, frequencies will need to work together. In...

Over the past several years, we have witnessed an impressive change in the size and capabilities of cellular phones and their individual components. First generation cellular phones for analog cellular networks were very big and for voice processing only. Today, on the other hand, Over the past several years, we have witnessed an impressive change in the size and capabilities of cellular phones and their individual components. First generation cellular phones for analog cellular networks were very big and for voice processing only. Today, on the other hand, The tracking devices for people is a key hardware component for any LBIS utilizing the mobile-based location provider architecture, like the real-time tracking system example described in this blog. The GPS receiver is important not only because no position will be available to the application without it but also because of its features and performance. There is always the trade-off between cost and quality, and the GPS chip is n...

Since the first generation GPS chip was presented to the public, it overcomes some problems: unclear signal of ex-chip, long positioning time, location drifting, etc. Due to the progress of chip manufacturing procedure and size reduction, even PDA, digital camera, cell phone and so on can be integrated with GPS. The personal vehicle tracking devices equipped on the vehicles is simple and more accuracy than dead reckoning method. It is getting to be used as basic vehicle equipment. Conversely, some disadvantages of GPS still need to be addressed. For example, if a cell phone or radio’s wave band is closed to GPS’, it would cause interference. In addition, tunnels and weather would affect the accuracy of GPS also. Thus, adjusting GPS error by a fixed base station and then conveying it to the vehicles’ GPS for correcting can add accuracy. It is called Differential GPS (namely D-GPS). The FM radio can also receive the positioning signal from the base station. Vehicle Tracking The GPS ...

So what is coming? Some day there may be as many as 80 satellites from GPS, GLONASS, GALILEO, QZSS, and others. If so the systems will provide users with a variety of signals and codes. The availability of many more satellites will enable new applications in areas where the current lack of satellites has been a hindrance. For civil users, Personal GPS tracker will provide more protection from interference, ability to compensate for ionospheric delays with pseudoranges, and wide-laning or even trianing capabilities. For military users, there will be greater antijam capability and security. For everybody, there will be improvement in accuracy, availability, integrity, and reliability. It looks as if the GNSS is on its way. So it is no surprise that there is great anticipation from a business perspective, but from a user’s point of view the situation is not unlike the advent of GPS more than 30 years ago. Much is promised but little assured. New capabilities will be available, but exac...

With dynamic growth and acceptance of mobile devices, many innovative business applications are beginning to emerge. GPS phone and tracing seems to be one of the popular applications which many organisations have initiated, often facilitated by location based services provided by mobile network operators. However, there are many issues associated with the provisioning of this application with current technologies and business models. Small and Medium size Enterprises (SMEs) that make up a significant segment of businesses worldwide do not yet seem able to benefit widely from these services. In this chapter, we initially review current technologies/ applications and the issues associated with them, drawing from research and the experiences of a long term ongoing action research project with SMEs in the trade sector. Subsequently, we explore the opportunities offered by 3G services/business applications to SMEs, and provide a broad critical outlook on future opportunities for SMEs to be...

Most, not all, GPS surveying relies on the idea of differential positioning. The modeof a base or reference receiver at a known location logging data at the same time as a receiver at an unknown location together provide the fundamental info rmation for the determination of accurate coordinates. While this basic approach remains today, the majority of electronic tracking device surveying is not done in the static postprocessed mode just described. Postprocessing is most often applied to control work. Now, the most commonly used methods utilize receivers on reference stations that provide correction signals to the end user via a data link sometimes over the Internet, radio signal, or cell phone and often in real-time. In this category of GPS surveying work there is sometimes a distinction made between code-based, DGPS, and carrier based, RTK, solutions. In fact, most systems use a combination of code and carrier measurements so the distinction is more a matter of emphasis rather than...

The Federal Geodetic Control Committee (FGCC) has written provisional accuracy standards for GPS relative positioning techniques. The older standards of first, second, and third order are classified under the group C in the new scheme. In the past, the cost of achieving first-order accuracy was considered beyond the reach of most conventional surveyors. Besides, surveyors often said that such results were far in excess of their needs anyway. The burden of the equipment, techniques, and planning that is required to reach its 2σ relative error ratio of 1 part in 100,000 was something most surveyors were happy to leave to government agencies. But the FGCC’s proposed new standards of B, A, and AA are respectively 10, 100, and 1000 times more accurate than the old first-order. The attainment of these accuracies does not require corresponding 10-, 100-, and 1000-fold increases in equipment, training, personnel, or effort. They are now well within the reach of private GPS surveyors both econo...

If a static tracking device control survey is carefully planned, it usually progresses smoothly. The technology has virtually conquered two stumbling blocks that have defeated the plans of conventional surveyors for generations. Inclement weather does not disrupt GPS observations, and a lack of intervisibility between stations is of no concern whatsoever, at least in postprocessed GPS. Still, electronic tracking devices is far from so independent of conditions in the sky and on the ground that the process of designing a survey can now be reduced to points-per-day formulas, as some would like. Even with falling costs, the initial investment in GPS remains large by most surveyors’ standards. However, there is seldom anything more expensive in a GPS project than a surprise. New Design Criteria These upgrades in accuracy standards not only accommodate control by static GPS; they also have cast survey design into a new light for many surveyors. Nevertheless, it is not correct to say th...
